YTMND is a site on my bookmarks toolbar so I have easy access to it. I go there a couple of times a day to see some of their stuff. And my favorite comedy is, of course, Seinfeld. A recent sitcom that I enjoy is Arrested Development. I think I've enjoyed most of the comedy cartoons: Family Guy (this has overtaken The Simpsons has funniest for me), The Simpsons, South Park, King of the Hill, Beavis and Butthead, Duckman, Ren and Stimpy, The Critic, the old school Warner Brother's show, Aqua Teen Hunger Force, and Space Ghost. Then there is British comedy which is a whole different ballpark. I like Keeping Up Appearances, Are You Being Served?, Allo Allo, Fawlty Towers, Waiting for God, The Office, and of course, Monty Python's Flying Circus. For late night TV I watch either Letterman, Conan, or The Daily Show. Leno blows chunks. And then there's sketch comedy and improv like SNL (from the beginning to early-mid 90s only), Kids in the Hall, and Whose Line is it Anyway? (Both UK and US versions).
