I saw Demetri Martin live at the Boulder theater and he was absolutely hilarious. With art, film, music, and of course stand-up under his belt, I think he's my generations best renaissance man.

Dane Cook is hit or miss with me. Some of his stuff splits my sides, other stuff is just stupid.

Oh, and Chris Rock is great. I'm guessing you have to be a little more involved with the black community to get into his stuff, but if you are, he's hilarious.

And of course the classic Seinfeld, Carlin, Hicks, Cosby, and Pryor are amazing.
