I'll throw in a vote for Braveheart as well, because it provided one of my favorite movie experiences ever.
Watching the movie with a girl, when he drops the cloth she says "Well, at least they didn't hurt him." WTF?!? Everyone yelled at her, and a good time was had by all. Except her.
Also, the next week, same girl watches American History X. The scene after the jail rape, where Norton is walking funny, she timidly asks, "Did they cut him?" Another girl just yells "No, they fucked him in the ass, moron."
Makes me wish you needed to get a license or permit to watch movies.
