How to beat Ornstein and Smough in 4 minutes - Dark Souls 1 bosses

As Smough is slow and his moves are telegraphed, try to take out Ornstein first. Keep tracking back and try to use the pillars to seperate the two. Try to aggro Ornstein into lunging at you, so he's far enough away from Smough to land a few hits on him, then retreat. Don't get impatient.
Raging Smough isn't too hard, as with all DS bosses, roll behind him and wallop him in the arse.
You can do it!!
