Duke Nukem 3D Easter Eggs compilation

UPDATE (October 2020): well, since this is by far my most viewed video I thought it was about time to make a small update in the description. Regarding the video itself, I must admit, as many of you have already stated in the comments, that there are quite a few mistakes here und there, like the "Moger Roore" reference, for instance, and also many missing easter eggs. I really don't think I'm going to release an updated video on this specific topic anymore though. Instead, I've just recorded a walkthrough of the whole game showing pretty much every secret/trick/easter egg shown in this video (apart from those that require cheating in order to be accessed). Here's the link in case you're interested:

Original description: Well, here I made this compilation of every easter egg, funny reference and hidden message* I know in Duke Nukem 3D Atomic Edition. Sorry if the video edition is not top-notch, I tried to do my best hehe. I really hope you enjoy it!
Special thanks to Keith McLeod for his FAQ at gamefaqs.com, which is where I learned most of these easter eggs.
= please note that I didn't include in the compilation any of the hidden messages meant to be seen using the night vision goggles, as they are not easter eggs, but give hints about ingame secrets.
