South Park

It's brilliant. They didn't just take some famous cinematic rape scenes for comedic reference, they recreated them so close to the original sources that it doesn't quite parody them to the point of complete humor. The only thing funny are the identities of the characters being portrayed, but the scenes themselves were just about as uncomfortably gross as they were in the original movies. Really makes you think Trey and Matt must have felt pretty strong about this subject if they wanted their audience to a bit more disgust than usual. And hey, the whole episode is about cinematic integrity, so paying homage to these famous film scenes is an extra bonus.
