no real favorite, but..
You know, all Dave Chappelle has to do is open his mouth. Heck, I'll laugh for no reason when I just look at a picture of Dave Chappelle. Funniness just eminates from him. It's like his natural aura. He's on another level compared to other comedians in terms of funny'ing.
I can probably say the same for Chris Rock, lol. He can talk about the most boring subject in the world, and end it with "Shut..The..Fsck..Up" and I'll laugh. hahahaha.
Russel Peters is getting there. He's awesome with the crowd. He is among the comedians who can improv w/ the crowd really well, and he feeds off the crowd. His facial expressions are too funny.
