Mine is Russell Peters: http://www.youtube.com/watch?v=Zge74dWHA3Q&feature=related Please post videos.
Russell Peters is one of my favorites, though some of his stuff is a bit repetitive. I like Daniel Tosh too.
Arty Lange, he is hilarious BTW (not to get off topic) Bebicul: Did you know they are making an arrested development movie
Wow, I've never heard of more then 1 or 2 of these people. I think I need more comedy in my life lol. I love Conan O'brian's opening act though... where he pulls his hips with the invisible strings lmao. Also love how he always makes fun of himself.
My favorites are both deceased. Very different styles but both brilliant in their own way: Bill Hicks & Mitch Hedberg.
I like Russel Peters, as well. His accents are incredible, but it's too bad he doesn't have a lot of new stuff.
Seinfield is my favorite can't stop laughing Plus all the guys from Laugh Factory I find Jeff Dunham genial and this act one of the best : http://www.youtube.com/watch?v=1uwOL4rB-go&feature=related
