RICKY GERVAIS SHOW - HOW TO GET TO HEAVEN
HTML-код
- Опубликовано: 20 янв 2011
- A different version of a classic exercise in logic. Another, more difficult version of this well-known brain teaser goes like this: "Two guards are standing in front of two doors, identical except one door has #1 on it, the other #2. One leads to Heaven and the other to Hell, the guards know which is which, but you don't. One guard always lies, and the other always tells the truth, but you don't know which does what. You can only ask one of them one question in order to find out which door leads to Heaven - and the guards have no knowledge of the world around them, except which door leads to heaven and which leads to hell, and whether the other guard lies or tells the truth. So the guards can't answer any questions like 'How many heads do you have?' or the like, although, in this scenario, those questions would be useless anyway because you don't know which door the liar and truth-teller is guarding. So what question would you ask?"
The answer is: "What would the other guard say if I asked him which door leads to Heaven--door #1 or door #2?."
Assuming door # 2 leads to Heaven, if you ask the liar, he will say "the other guard will say door #1". If you ask the truthful guard, who knows the other guard always lies, he will say "the other guard will say door #1". You then know, through logical deduction, that door #2 actually leads to Heaven. It makes no difference which doors the liar and the truth-teller are guarding. It works the same either way. The important element is that the guards are talking about the nature of the doors themselves, not the nature of the doors they're guarding.
But Ricky stipulates at the start that the liar is guarding the door to Hell, and the truth-teller guards the door to Heaven. The way Ricky frames the "right" question - "What would the other guard say if I asked him which door he was guarding?" - would result in one guard answering "Hell", and the other "Heaven"-- the liar standing in front of the door to Hell would lie and say "the other guard would say he is guarding the door to Hell', while the truthful guard in front of the door to Heaven, knowing the other would lie, would tell the truth and say "the other guard would say he is guarding the door to Heaven". You would then logically assume that the guard who said "The other guard would say "Heaven" was standing in front of the door to Heaven, and the one who said "The other guard would say "Hell" is actually guarding Hell.
But I don't think any of them, including Ricky, realize that a much simpler way to solve Ricky's version of the puzzle is to ask either of the guards if they're standing on their heads.

Karl doesn't just think outside the box, he literally dismantles the box into separate pieces, calls the manufacturer, and asks why they've built such a shoddy box
Got some post for god here.. is he in ?
Then he had a go at the tree for producing such shoddy cardboard
Boxes. Do we need'em?
Like Father Ted "shoddy workmanship!"
I like how instead of thinking some way to get past this with questions, Karl immediatly tries to cheese it by checking if the doors feel different or peeking through the keyhole
That's the sign of a dope. He's not engaging with the thought problem.
why's your pfp a fat sypha, what the fuck
If this bit was a DnD campaign, he'd be a pretty typical player, lol. Ricky definitely has DM personality.
I immediately knew that Ricky would choose the door to hell, immediately.
Mariah Osborne imagine Ricky and Carl spending eternity with each other in hell
I knew Ricky would be a demon.
Same here, and I wish I was wrong. I don’t think I like Ricky anymore
Mariah Osborne same here but I thought they would double-bluff and let Ricky guard Heaven

"look lads,I'm just trying to do a job 'ere" genius
You’re an idiot.
@@cateatsowl826 you're
🤣🤣🤣
I would like to take this moment to say I love Karl's solution of being some interdimensional postie to get in
stop messing about, I ave a job to do ere xD
The best part is that Ricky is acting so superior, saying how people cant wrap their heads around it, and he gets the riddle wrong, the answer wrong, and doesnt even notice it.
Clever lad.
The worst part is as the start when he says something like “I’ve told people the answer to this and they still can’t comprehend it” like he came up with the riddle
In the original podcasts I seem to remember Ricky saying the next week that he'd mucked it up and that you're not meant to know which guards which
Easiest question: "Are you guarding a door?"
What? To solve the original problem? No, just no. Ricky Gervais told the conundrum wrong, but that is no excuse to join the fallacy in his explanation.
It is never stated that the liar is guarding the bad door/path and that the honest one guards the true door/path. Asking if they are guarding a door just means you figure out which is the liar and which is honest, but that says nothing about what door or path is actually correct. Yet you then waste your one question.
And if you ask "Are you guarding the door of truth/correct path?", both will answer you with "YES" and you learn nothing.
You are Karl Pilkington.
You're right that Ricky told the riddle wrong, but that's really not happysquidNET's problem. He heard a riddle from Ricky and solved it correctly.
The problem is niether is supposed to he guarding a door.
I would have asked "Did I just ask you a question"
How would you know who's lying and who's telling the truth? Silly git.
There's always a little snidey one....and then they change the guard's face to Ricky. Brilliant.
I honestly think the Ricky Gervais Show is genius, it's original and incredibly hilarious, and the three of them feed off each other so well it's brilliant. Can't wait for the new season.
Surely you can just say:
"What's 2+2?"
If you get an answer that is anything but 4, obviously that's hell?
No because you don't know who's guarding what the liar could be guarding heaven or vice versa
@B T But without knowing which door the liar is guarding you've still no idea which is which even if you know which one's lying.
That's even simpler didn't understand Ricky's
what if neither guard knows math?
The thing is if I said 2+2=5 for instance. That wouldn't make me a liar, it would just make me really shit at maths.
Let’s say you’re a bloke, “Am I woman”
“Yes”
“right you’re guarding hell”
But the truthful one could be guarding hell
Ricky fucked up. The liar does not always guard the door to hell and the truth teller does not always guard the door to heaven. Otherwise you can simply ask "How many doors are there?"
Or any question to which the truth is obvious.
NoNameC68 I would have held up and pointed to my hand and asked what it is.
Kathy H
Yeah? So you used your one question to know which one tells the truth, now you can't find out which door is the good one.
The question has to be compound and ambiguous. Asking the liar which door the truth teller would send you through produces the hell door because the onus has been passed from you to the guard. Asking the truth teller which door the liar would send you through produces the hell door.
In your selection, you negate the negative produced in the question. If you believe either of them, you die.
Yes but in this video Ricky states that in this scenario the door to Heaven is always guarded by the one that tells the truth which is why the original comment is pointing out that flaw in Ricky's question.
just ask "is heaven real?"
This question was told on a radio program many years ago in Hong Kong, like 1993, and I remember my classmate took it to the class. My maths teacher love it so much and decide to let us play this for the whole class and no maths teaching. And, I'm happy to say I was the first one to crack down this question. My teacher only got it after I explained three times, and many classmates never understood.
i could listen to carl for hours his train of thought not only amuses me but also he can actually come out with some gems... pure class!!!
Right Ricky told the riddle wrong. One of the guards will tell the truth and the other will tell a lie but they can be guarding either heaven or hell the one telling the truth could be guarding hell and the one telling the lie could be guarding heaven. You don't know which door their guarding. So when you give the question whatever the guard says is the door they are guarding.
Spot on.
What? How does that work? Which question? Asking what the other guard would say?
Edit: I get it now.
If you ask either one of them "which door will the other guard say is the door to hell" they will always respond with the door to heaven.
This is because the liar knows the truth teller would give you the real door to hell, so he must point to the other door since he must lie.
The one speaking the truth knows the other guard is a liar, so he knows that the other guard is going to tell you that the real door to heaven is for hell.
Jacob O'C
It is fixed for the precise reason you brought up in your first comment.
The guard telling the truth KNOWS the other guard is a liar.
This isn’t explicitly stated but it’s implied by the fact that the guard telling the truth can ONLY tell the truth. And that the guard telling a lie can ONLY tell a lie.
If they didn’t know what the other guard was going to say neither of these things would be true. You can’t always tell the truth unless you know everything there is. The same goes for lying. You can’t lie about what someone’s going to say unless you know that person always tell the truth.
The implication of them always lying or always telling the truth is that they are ethereal beings that have a complete knowledge of the world.
So in your own example where the liar is guarding Heaven, the door to heaven is still going to be the one BOTH GUARDS dictate as “Hell.”
For example: If you ask the truthful guard who is guarding the door to hell, “what door is the other guard going to say he’s guarding?”
The truthful guard will tell you that the liar guarding heaven will SAY that he is guarding Hell.
He knows this because he can only tell the truth. It implies a limitless understanding.
Jacob O'C Lol this is an old comment.
One of my own comments distorted the answer to the riddle as well. I hope I can clarify what I believe to be the whole answer.
The complete answer to the riddle is: Ask either of the two guards “which door is the other guard going to say is the door to hell?”
You do not have to know which guard is guarding either door.
Here’s how it works: By asking a guard what the other guard will say, you are guaranteed that the response will be a lie.
Since you know it’s going to be a lie, asking the question: “which door will the other guard say is the door to hell?” Both guards will have to point to the door to heaven.
The guard who tells the truth will tell you that the liar is going to call the door to heaven the door to hell. So he points you to Door A.
Or
The guard who lies is going to lie about which door the other guard would say is actually hell. Which means he’s going to point to the door to heaven, which is still Door A.
We know from there that since Door A is the door to heaven, Door B must be the real door to hell.
If you ask instead “what door will the other guard say is the door to heaven?” The guards would instead point to Door B.
Once again, the key is to get the liar involved in a specific question. This is because he will always corrupt the response.
In the same way that 1 x - 1 = -1 and -1 x 1 = -1. The liar’s participation will always give the opposite of what you asked.
Yes, originally it was a crossroads with two people, one from the liar tribe etc...interestingly the logical solution has something to do with "i"; the square root of minus one.
Sorry, read above comment after commenting!
“got some post for god here... and it needs to be signed. is god in?😂😂😂😂😂
‘Erm, got some ah, got some post for God ‘ere 😂🤣
In his own inimitable way Karl is an absolute genius. Ricky is right to say he's the funniest man alive.
Ok, so. Ricky tells us specifically that the one guarding hell ALWAYS tells a lie. And the one guarding heaven ALWAYS tells the truth. So you know that. You don't know what door is what, or which door the one who lies stands in front of.
But if you ask any question like "what colour are your eyes" or "what colour is your hair", or "what is 5x5". The both of the guards are identical. So by asking one "what colour is your hair". So let's presume those two IDENTICAL guards have brown eyes. You would gather that it was heaven or hell based on their answers. If you asked heaven the question, he would tell the truth and say that his eyes were brown. So you would know that he had told the truth. But if you asked devil, he would have to lie as no matter what you ask, he will ALWAYS lie. So he would have to lie by saying a colour that wasn't his eye colour. Therefore you would know that he is lying and that is hell.
Surprised Ricky didn't think of this. Think about it and tell me ur thoughts
Look at the description
I thought it's seemed too simple
One eye
Dylan Fraser eaxactly what I was thinking there numerous ways around this
No no, In the original riddle and in this one you don’t know who’s guarding which door. So if you ask “Satan” what colour his hair is and he said blue despite the fact you know his hair isn’t blue thus helping you realise he’s the lier, you still don’t know which door he’s in front of. The legitimate only question you can ask is “which door would the other person say he’s guarding” because then you see who the lier is and which door is which.
Karl’s so lateral he’s actually extremely intelligent in that respect
Samurai Jack made a similar episode about this, his answer was " if you were your brother, which one is the liar".
It also appeared in the film Labyrinth.
I feel like if I asked "is Hell a good place to go?" that would be the end of that.
"But would they be neighbors like this, would they be that close?", how could you not love Karl.
Ricky explains the question totally wrong here. That's why it's hard to understand and everyone on here is arguing. The question Karl is to ask is supposed to be about the doors and how he can work out which is heaven and which is hell. Devil will lie. God will tell truth. So to solve the puzzle Karl is supposed to ask one of them what door the other one would tell him to enter. Then all he has to do is enter the opposite door to the answer he is given then he is in heaven. Simple.
John Hall how about if he asked God (unknowingly) and goes into the opposite door?
You're the only person i saw here that had the right answer, or better say the right question. People didnt seem to understand that you cant just find out who is lying and telling the truth, you need to know the doors they are actually guarding
@@jacoboc2244 what an unfun way to dissect the riddle lol of course the guards would know what door the other would pick and they’re the devil and an angel so they by default would care.
You don't know whether it's the liar or the truth teller guarding the Heaven door.
The questions you ask is -
If I asked the other guard to point to Heaven, which door would he point towards? You then go to the opposite of whatever he points to. No matter who's guarding what door, they will always point to hell.
OH I get it now, thanks :)
Smart one
The fact that Karl still went for it after Ricky told him the answer is absolutely amazing! Hahahahha
If two identical people guarded the doors, I'd just ask one of them if they looked the same and if he'd answer no then I'd know.
***** He gave a complicated answer partly because he likes to challenge Karl as far as possible, but also because it is the original answer to the ages old conundrum.
So what you can just trick one into lying? Wow it cant be that easy can it?
Actually they phrased the question wrong in the video you're not supposed to know which door the guards are guarding and you can only ask one guard a single question. You wouldnt know which guard you got when you asked and you dont get any follow up questions. That way you have to use rickys question.
***** You don't know which guard guards which door if the riddle is told properly.
Rose Jamal Ali you ask the devil = he says no, you can see he's lying.
THIS IS HOW ITS SOLVED,
if asked "what door will the other guard tell me he is guarding?" to the guard of hell he will reply "he'll tell you he's guarding hell" which is a lie as the guard of heaven would actually tell you he's guarding heaven
if you ask the guard guarding heaven "what door will the other guard tell me he is guarding?" the guard of heaven will say " he will tell you he is guarding heaven" which is the truth as the guard of hell would lie and say he is guarding heaven..
RICKY GOT IT RIGHT BUT EXPLAINED IT VERY POORLY
ALSO THE GUARDS ONLY KNOW ABOUT EACH OTHER AND THE DOORS. WHICH RICKY DOESN'T MENTION. so saying like "how many eyes do i have" or "are you guarding a door" is not allowed and takes away from the whole logical exercise.
You could equally ask, "Is it true that one of you two will lie lie to me?"
Andrew Boreland You can only ask them one question remember. And even after you discover which when is lying you still won't know which door they are guarding.
RandomRowan13 No, if I'm not mistaken, I could ask just one of them 'Is it true that one of you two will lie to me?' I will instantly find out. The devil will deny it, whereas the angel would say, 'Yeah, it's him'.
Then again, the devil could tell a half-truth and say 'Yes, someone will lie' (telling the truth), then lie by saying 'It's the other guy!'.
It's not exactly clear if the devil lies everytime. If so you could ask him any question which you already knew the answer to, Eg. 'Was my father's name 'John'?'
Lost now.
Andrew Boreland Keep in mind that Ricky explained this riddle wrong, the original riddle doesn't say the liar is always hell.
RandomRowan13 Ahh I see!
Thanks.
"This is where you use your gut feeling, innit"
Seconding some other peeps begging for a full version! This sounds divine ❤️😭
I have an alternative solution which is using the assumption that the angel would be happy and devil unhappy if you choose heaven door and vice versa.
(Read description for actual problem, not solving the one Ricky said)
The question is simple: Would you be happy if I pick door #1
If the door is heaven and you ask the good guy, he would say: Yes and not be lying.
If the door is heaven and you ask the bad guy, he would say: Yes and be lying.
In both cases they say Yes if you chose to ask about the correct door.
If the door is hell and you ask the good guy, he would say: No and not be lying.
If the door is hell and you ask the bad guy he would say: No and be lying.
In both cases they both say No if you chose to ask about the wrong door and Yes if you asked about the right door.
Solved, given the initial assumption, which is not that unlikely and not such a big stretch!
I love the animation!
You ask them "is there a door behind you?"
Oh man, this seriously took a long time for me to figure out how on earth this would work. But, I've finally got it. Thank you, my brain can now relax.
The animation on this is absolutely 5-star!
Without it this brilliant series would not be nearly what it is...
you have to watch their old XFM days there good to listen too and full of Karl. no animation but still as funny and they have LOADs of episodes
haz1510 Wonderful - thank you very much!
A lot of the material for this series is the same but still good - Glad to help
One could also ask any question with a known answer. "What color is my shirt?" if the response isn't correct (because one person ALWAYS lies) then they are guarding hell. If the response is correct then they are guarding heaven.
Look at the description
It still works. Incidentally this riddle was in the movie labyrinth
''and the guards have no knowledge of the world around them, except which door leads to heaven and which leads to hell, and whether the other guard lies or tells the truth.''
Haha fking brillant!
Wouldnt work. Riddle was told wrong the doors to Heaven and Hell are guarded by 2 guards of which one always lies and one always tells the truth. You dont know which guard is which.
I was watchin something the other night where these dudes were trying to get in through doors by a similar situation but they werent allowed to ask about anything but the door. This one dude tried saying "what color are my pants" and "what is 1+1" but then they ripped his face off. I didnt get to finish watchin and i didnt know what the show/movie was, I was just flipping channels to see how they got in so Im very confused to how this works. would someone please explain this to me? I really don't understand sadly.
This example is done poorly, cause here you can just ask what's 1+1, because you know that "god" is guarding the door you want to get to. and the "devil" is guarding the bad door, so here you can get the awnser simply by figuring out whitch guard is whitch.
However there is another one that much more difficult (something about 2 jailors and 1 door = freedom the other door = prison) and in that example you cannot deduce the awnser simply by figuring out the guards, since there is no (Good or Bad guards) just good or bad doors.
***** LOlwut
JaxBlade ask them if they’re standing in front of a door
"What color is the door?" *drops mic*
This question popped up in my head whilst showering. The answer i came up with was to ask an obvious question that you know the answer to. "Am i dead?" Then you can easily know who's lying or not.
The Ricky gervais show is the best creation in human history
“Are you a guard?” Would do it.
Yeah you are correct. I'm certain the original wording of this puzzle is they are not mentioned as guards as it as you stated that Wi get you the answer.
The poster of this video said it but my answer to this question was, "Am I wearing a shirt?" The solution is trivial. The riddle should be, "You have to ask 1 question for which you do not know the answer."
''and the guards have no knowledge of the world around them, except which door leads to heaven and which leads to hell, and whether the other guard lies or tells the truth.'''
The one who always lies doesn't necessarily guard the door to hell and vice versa.
When I was a kid I heard this as one brother that lies and one brother that tells the truth. Less unnecessary set up, then this heaven and hell stuff.
"If you were your brother what would you tell me" -then do the opposite... Its so easy.
I missed the part where he said the truthful guard knows the other guard lies, and the one that lies knows the other tells the truth. To get into heaven you can't just determine which one the dishonest one is by asking one of them if they are standing on their heads then simply enter the door if that guard says "no" because another specification was that the dishonest one could be guarding heaven (you don't know if the dishonest one is guarding heaven or hell). So the only question to ask that would work without a doubt is, "what would the other guard say if I asked him wich door leads to heaven -door 1 or door 2"
isn't the right answer to ask what the other guy would say is the right door, and then go through the other door?
Ask what the other one would say they were guarding, and whatever the answer is, is the door that they themselves are guarding, the liar would lie and say the wrong answer which means he'd have to be stood in front of that one, the honest one would know that the liar would lie and say the opposite too, so he would have to be in front of that one. e.g If the liar is guarding door A he would say the truthful one would say door A, The truthful one guarding door B would know that the other would lie about guarding door A and instead say B.
Ricky's answer doesn't 't make sense to me.
Ricky's way is completely wrong and proved it in the video :P
If your name was Karl, you could ask is my name Karl?
The devil would say no and the saint would say yes.
I don't think you understand. It doesn't matter if they look they same, the question is how you solve it.
If the devil looked like the devil I wouldn't need to ask the quest in the first place.
Ok I'll explain it again for you. we'll pretend your the one standing at the gates to make this easy.
You would ask "Is my name Rose?" to either one of them. If it was the devil who can only lie he could only say "No, your name is not Rose." because he can only lie. He can't say "Yes your name is Rose." because he can only lie.
If you got a God and not the devil his only response could be "Yes, your name is Rose." because he can only tell the truth.
So no need for a second question no matter what. If you don't understand after this I give up or take it your a weird troll. Just think about it for a second.
My answer was based on if the devil could ONLY lie, if he was allowed to tell the truth too it would never work.
I think Ricky said he could only lie but its been a while since I watch the video. I might look up the other version of it some time.
5:04 I always lose it when I see Ricky's cartoon face on the snidey guard.
'Is my shirt red?' (it is red, the angel would say yes, the demon would lie and say it isn't red)
Just ask them how many fingers they have.
you still wouldnt know which door they were guarding
A good question would be: What's 2+2?
The one guarding hell would answer 4 and another guy 5.
But the guard who lies isnt necessarily in front of the door to hell
I was in Combinatorics today and the professor asked a question "How can you prove that every year has at least 5 months with 5 Sundays?" A student answered and the dialogue went something like this:
Student: Go get a Calendar and count the Sundays on it?
Professor: So you're going to go get every calendar and count all the Sundays on them?
It reminded me of a Ricky Karl dialogue and specifically this video. I'd love to hear Karl's take on combinatorics questions
"This is where you need to use your gut feeling"
"What as opposed to the pure logic that Ricky just used"
It's sad that there are actually so many people out there who ignore logic and make decisions based on their gut feeling.....
Why couldn’t you ask one of the guards to just open the door? 😂🤔
...because we're all stupid apparently
"What gender am I?"
Devil: 😶
God: 😶
In the early days, Ricky and Steve would pick on Karl in a very direct way. As they moved beyond XFM to the podcasts, however, they realized that Karl was almost completely unable to consider the metaphorical without reverting to the literal. So sayings such as "people in glass houses shouldn't throw stones" would result in Karl saying that people used to live in "simple glass houses".
It has been said that much of the comedy came from Karl's innocence, and to a lesser extent his insularity. But the truth is that most of it came from his refusal to answer questions with "I don't know".
This one was always going to be impossible for Karl, because it went way beyond simple metaphor and into problem solving. Even when Ricky explained it, it was obvious that Karl wasn't listening.
He doesn't have to forget, as it's a compulsion he isn't conscious of. It fits with the "he always lies" part of the problem, as there is no explanation of the motivation for the lie, or whether he lies uncontrollably or not.
If he always lies, even when contemplating a hypothetical in his own head, then he may never answer the question. He could get stuck in an infinite loop lying to himself, "I would pick this door - no I wouldn't - yes I would".
Ask any guard what the other guard would have point out as the door of heaven. They will both point ou the doors of hell.
Ask any guard what the other guard would have point out as the door of hell. They'll both point out the door of heaven.
Matthieu Veyrat They would just point at each other's doors.
You don’t ask what door they’re guarding that’s the wrong question. the right question is “if I was to ask the other guy which door LEADS TO HEAVEN what he would say” not which door he was guarding
Let’s say you go to the devil and you say to him “if I was to ask the angel which door leads to heaven what would he say?” And the devil would point to his own door because he’s lying. So you would choose the opposite now. Now, if you said to the angel “ if I were to ask the devil which door leads to heaven what would he say?” And the angel would point to the devils door aswell because he knows that the devil lies. So they would both be pointing at the devils door so you have to choose the opposite.
SauberC10 both of them would be pointing at the devils door so you choose the opposite
@@jamieemm9767 I still don't get it, I mean, what if you asked the angel first without knowing that he was the angel and he points to himself? wouldn't you be going to hell then?
I don't get it.
So if I asked the Devil "what door are you guarding", and he lies (which I wouldn't know) and says "Heaven"
I then open the door into Hell..
+StoodStill That's why you woulnt ask that question
+xxxEmstarxxx What?
StoodStill Were you confused about the answer to the riddle?
I'd just hold up two fingers and ask "Am I holding up two fingers?"
you've nailed it man perfect question
"If you were the other guard, which door would you say goes to heaven?"
They will both say the door to hell so pick the other one
What?
You could just ask "what colours my hair?"
Glad you went through that cos I was struggling with the answer!! Cheers, by the way, if I'm ever in this situation (lol) I'll just ask if they're standing on their heads!!
The more useful version of this problem is when they aren't guarding specific doors, but are directing the questioner to their preferred door (truthsayer->heaven, liar->hell). That way trivially determining if one is a liar doesn't resolve the problem.
Well yes it would because you would allow yourself to be directed to the truthful guard's preferred door lol
"What colour is your hair?"
Could literally ask anything.
Thought the same, like asking what my name is
Well in ricky’s interpretation, that would work, but what he didn’t explain that it’s also unknown if the guards are in their respective positions, the honest guard could be in front of the door to hell for all you know, meaning that you can now rule out who the liar is, but you blew your only question on either guard and you still have no read on what door leads where.
Simplified explanation
Let's say door A is hell (the liar)
And door B is heaven (the truth teller)
1) If you ask door A (liar / hell), what would the other guard say if I had asked him what door he is guarding. Guard A would say, hell. (which would be a lie since door B tells the truth and would say "heaven" if you asked him what door he is guarding)
So if the guard you ask answers "hell" you know hell is behind the guy you just asked.
If you ask door B (truth teller / heaven) , what would the other guard would say if I had asked what door he is guarding. Guard B would say, heaven, (which would be the truth, since door B is Hell, but the guard would lie and say heaven)
So if the guard you ask answers "heaven" you know heaven is behind the guy you just asked.
To this "what would the other guy answer" question, the liar will always answer "hell" and the truth teller will always answer "heaven". This happens because both the liar and the truth teller would in fact answer "heaven". but the liar is lying, so when you twist the question, the liar know answer hell.
This way of asking, forces the answer "Hell" out of the liar. However the truth tell can never say hell, since he know that the other guard would lie and say heaven.
Having said that, if there are no restrictions (which there normally is) you can just ask any question that you know the true answer to. Is 2 + 2 = 5, are my pants green and so on. But I think there must be some restriction to what you can ask about or something, or this is kind of an easy riddle. At least I know that "is 2 + 2 = 5" came to my mind in about 3 seconds.
3:21 *faceslap* no let him finish!
The proper way to shut a
friend up😂
So the original riddle is there is a liar and a truth teller but you dont know who is infront of which door.
You ask either one of them "If I asked the other guard about which door leads to heaven, which door would he tell me."
The truth teller would tell you the one that leads to hell because the other guard would lie
The liar would tell you the door that leads to hell because the other guard would tell the truth but the liar is lying about what he would say.
Hence, choose the other door and get to heaven.
Ricky explained the riddle wrong and his answer is wrong.
His answer was: to ask what the other guard would say if you asked him what door he was guarding. Both of them would say hell (in accordance to the way he says the riddle), so you wouldnt know which door is which.
Ask this. Are you guarding this door? eazy
Pretty good.
Yeah but you dont know what the liar is guarding nor what the truth teller is garuding
Just say a math question you know the right answer to 2+2 =

“Can I go in without permission?”
This works..
I was thinking about it. if you ask the one guard: 'what would the other guard say my door is?'
You'll get 1 answer: either heaven or hell. Just go in the one that says hell.
If he says heaven, then it must be the devil, as that guard says the other one will say, that that guard is guarding heaven. Only the devil will try to trick you, he wants to always pretend he's guarding heaven.
If he says hell, he must be guarding heaven as that guard is saying the other guard will say he's guarding hell. The devil never would want to make the association that he's guarding hell.
This is my take on it.
Easy
Ask, whats 1 + 1
if it dont equal 2
Then his lying
+Allan T But that doesn't tell you which door is the one to Heaven.
I like your question to the answer better
Michael Grey Why? It doesn't get you anywhere. It just tells you which guard is the liar, NOT which door to take.

@@SevenEllen oh my god, its a problem solving exercise, not real life. We know from what we have been told that the liar guards hell and the honest one guards heaven. One question to determine which one is guarding heaven or hell
I would just ask the guard "do you and the other guard look identical?" and if they say yes then it's heaven if they say no it's hell.
Ricky's question both would answer the other guy is guarding hell
"If I asked the other one 'what door are you guarding' what would they say?". If you asked the angel, they'd say the other guy would say heaven because he's going to lie and say heaven (when he's guarding hell). If you asked the demon he'd say hell because the other guy would tell the truth and say he's guarding heaven which he is.
Ricky got it wrong though, you're not supposed to know which one will tell the truth and which one will lie so that question isn't supposed to work.
There isn't a loop that gives 100% chance of you going to heaven in the actual question (other than the only answer of course)
I love how smart Ricky always acts, but how he fucks up the question completely: The honest one is not necessarily standing in front of heaven.
this one always gets to my mind
Simple, ask "If i were here yesterday, which door would you say is correct?"
Truth teller would point to the correct door
Liar would point to the correct door too as he would lie about actually pointing to the wrong door if he were here yesterday.
Dinesh Kishore You can only ask one of them.
Dreqo Machael they will both point to the good door doesn't matter which one that you ask for.
+Dinesh Kishore Both would just say my door leads to heaven (assuming you mean heaven=correct)
time wouldn't matter, you could say that question in a seemingly infinite amount of ways but all you are really asking is, which door would you say is correct?
+JKOROX That's true. "Which door would YOU SAY is Heaven/correct/whatever?" specifically referring to what the guard would say, and not 'would you say' being used as a figure of speech. The truth-telling guard would point to the Heaven door, because he always tells the truth. But the lying guard can't point to the Hell door (which he SAYS is Heaven, but is actually Hell), because he ALWAYS lies, ergo he points to the Heaven door as well.
+Dinesh Kishore I don't understand how being there yesterday has an affect on the answer
you could also ask a something you know to be true like "is a parrot a bird?" one guarding heaven would say yes, and the one guarding hell would have to say no since yes is the correct answer, which would reveal the person saying no to be guarding hell
Ricky leaves out a very important clause from the original puzzle. Though one only tells the truth, and the other only tells lies, it isn't known whether the liar guards the door to hell or heaven. You only have one question with which you can decipher which door is which.
First question that came to me was "can you see me?"
3:05 and onwards laughed so fucking much
"I got some post to god here..."
and stephens animations slapping ricky in the face to shut him up!!! hahaha
My solution is adapted from a similar problem where there are two paths, I need to find out which ones which And figure out which path is which (each may be guarding either path) AND bring back proof that I solved it, with two questions, and I took a picture of each answer.
The questions I asked were:
"Which way is the correct path? Indicate by pointing" (If their arms cross each others, the truth teller is opposite the correct path etc.)
"Which way were you just pointing?" (the correct path.)
Best question to ask: "what am I thinking of?"
That's true. This makes so much more sense now.
"Are you standing behind a door?"
BOOOOM !!!!
To this day have no idea why people struggle with it. Initially it took me by surprise but as soon as you draw a diagram it becomes so obvious.
If he says no, he'd be lying initially. But it would be the truth because he didn't tell a lie. If he doesn't say anything afterwards, he was telling the truth.
No, The easiest and simplest way is to ask "Are you guarding a door." Whoever says "Yes!" (It will be heaven who say's yes) (And the devil will say no)
Tada!!! You are now in heaven!!!
which falls down straight away because you can only ask one of them a question. Yours is a 50/50.
Would they not both answer 'Hell'?
"If I were to ask the other guard about what he is guarding, what would he say?"
Heaven: "He is guarding Hell." [Telling the truth]
Hell: "He is guarding Hell." [Telling a lie]
I still don't know which one is actually guarding Hell because I don't know which one is lying...
Ricky explained the riddle badly. In this case, it is acceptable to ask: "Are these two doors identical?" or "Are you guarding a door?"
1) Ricky told Karl he could ask either of them 1:05 (ie one of them), so if Karl asked the question, he wouldn't be able to gather an answer
2) They'd both say "Hell". The one guarding Hell is going to lie about the other, and say "He'd say he's guarding Hell." The one guarding Heaven will tell the truth about the other, saying "He'd say he's guarding Hell". So you're still left with a 50.50 chance.
You ask them "Is this sentence false?"
The one guarding hell says "yes"
The one guarding heaven says "That's a paradox, it's neither true or false"
Read the description. Makes perfect sense
Karl didn't even know that he'd been told the answer. 😂
actually the puzzle was that the guards were not guarding the doors. they were like tho information booths. And you could only ask one. And there were two doors unrelated to the info-booths. You could only go through one door (obviously, for all non-electrons out there). So you had to ask "if I asked the other guy which door leads to heaven, what would he say?". And you had to go on the other door (to get to heaven)
If you hold your right hand up, and you ask "Which hand am I holding up", and say you're given the reply is "you're holding up your right hand", it then means the one who answers is guarding heaven.
If however they reply "you're holding up your left hand", it means the one who answers is guarding hell.
Therefore if they give you the correct answer, you enter that door, because that is heaven.
He would lie if he answered the question. Knowing what the answer is (the right door), and answering the question (the wrong door), are two different things. Saying "He would lie" doesn't change the fact that the answer he is thinking of could be different to the answer he would give if he actually answered. You aren't asking him two questions, so he doesn't have to lie twice. He only has to lie in the answer he gives you. He doesn't have to think, "Oh, I would point to the wrong door."
I'm convinced Karl is unable to understand hypotheticals. It's like there is not a abstraction engine in his head.
I was just showing a friend of mine that scene from Jim Henson's "Labyrinth" that goes into this same riddle -- and made the same connection. And then, I find this vid! LOL! Someone gets it, too. x)
