Demetri Martin is funny! I'm glad you put his name up because I couldn't think up his name for the life of me. Anyway, I love his comedy. It is very creative and different from what you usually see out there. It will crack you up!
Demetri Martin is the funniest guy I've ever seen. There was a special on Comedy Central a month or so ago. If it's on again, I suggest watching it. His jokes are ridiculously odd and true. He uses a lot of props, but don't call him Carrot Top, that guy isn't funny.
