Here is my recommend comedy viewing list. The full list is in alphabetical order (I didn't want to try to rank them) and the links take you to the Internet Movie Database where you can read reviews. I'm not saying that these are all great movies, but I do think they are all at least worth a video rental when you're desperate for some comedy.

You may also want to check out the Wikipedia List of Comedy Movies. You can browse through the listing hopefully find some good movies that you'd forgotten about. Another good way to find movie lists that fit your tastes is to enter several of your favorite movies in your favorite search engine (put each movie title in quotes) and find lists made by others that have similar tastes to you.

Anyway, here is my list.
