Funniest thing I've ever seen. The "You scratch my back, I'll scratch yours" was solid gold.
I have never laughed so hard in a movie before. Not quite as strong story-wise as Knocked Up or 40 Year Old Virgin, but equally, if not more, funny. Everything just fit nicely together. Chris Mintz is the new Napoleon Dynamite.
Very immature film, but that didn't stop me from enjoying it.
