Tom Greens Awesome. I saw him doing his standup act at a small, local comedy club last year and it was absolutely hilarious.
Freddy Got Fingereds a classic too. It's funny because a lot of it is actually autobiographical. The story was actually loosely based on his life: like the shit with his dad turning off all of the hot water and the family dinners ETC. " Dad, I'm a 27 year old man, I think I can eat a chicken sandwich".... Priceless.
His T.V. shows aged incredibly well too. I Bought one of his home videos on VHS not too long ago for a buck at some decrepit old video store... Couldn't stop laughing my ass off
