I still think I laughed more at Scott Pilgrim vs. The World. "I have to go pee on her!"
But yes, it is very consistently funny. The dialogue comes so fast and funny that a second viewing is assured, the situations are Jackass-levels of insanity,
and the movie brilliantly sidesteps getting too moral on us. When the 'main character/whip' is having doubts, his wife and kid rub his back and reassure him that he's supposed to blow himself up for them!
Gloriously politically in-correct, I'm glad to have seen this before finalizing my Top 10 of 2010!
