Repo Man: thouroughly punk rock sci-fi comedy and quinessential cult movie. Still makes me laugh. Great soundtrack, too. Underrated by the public in general, though it has its following.
Bill and Ted's Excellent Adventure: Not as braindead as it's made out to be. It's got some pretty clever gags, and it's a damned respectable movie, and still really funny. It's aged well.
I was gonna say Pee Wee's Big Adventure for my third, but I think that movie's actually still fairly popular.
