Query: A Knee-slapping Riot!

This movie was reccomended to me by a friend. One day on the bus ride home, she and everyone else were talking about how funny it was. I'd never seen it, and asked if I could borrow her copy. She let me, and let me tell you something: it's not the kind of movie that would make most people BURST out laughing right away -- it's more of that subltle type humor. If you tune into that, boy is it hilarious! Though there's some 'adult humor' I could definitely do without, overall the movie tickles me. I suggest it highly.
