I've recently noticed that my movie/video collection is in dire need of humor. Not because I don't like humor, it's just that most humor movies are bad enough for me to be embarassed to have them on my shelf. I need movies featuring sophisticated humor, black humor, unintentional humor, or else are just plain funny. For example, I think super troopers is great, because it's funny enough to not care about the actual movie. Ditto with some Monty Python material. But I simply find most 'comedy' movies (say, Wedding Crashers) painful. I think The Princess Bride has a lot of humor, but somehow manages to be good at the same time. What are some good, classic funny movies?
