Conan is the best, no contest. I guess I'm biased, though, since he has my sense of humor. Jimmy Fallon is the opposite of my humor, so I can't stand him. But I think he's a decent host, especially for being new. I've never really seen Craig or Jimmy Kimmell as funny. Jay was reasonably funny, but kind of a dofus. David Letterman is by far the worst. He was great in his hayday, but now he's a bitter, washed-out has-been. That's my opinion, anyway.
