For me its Chris rock, he's actually the only one who can make me laugh and makes sense. http://youtube.com/watch?v=INhrACfQMBM Yours?
I really like Russel Peters, he has some fantastic jokes, espicaly racist ones, but he is Indian himself and the jokes are really funny, without being to serious. They are fantastic for just forgetting about the world and work. He makes you relax and forget about any stress !
I go with the poster above me Jerry Seinfeld is the man. Kat Williams new dvd is hilarious tho everyone should check it out.
Check out BILL HICKS, he's a genius and philosopher, not just hilarious but deep. http://underdogcinema.com/culture/bill-hicks-legendary-one-night-stand/ http://underdogcinema.com/culture/bill-hicks-revelations/ RIP
