I've heard him a couple times. Personally, I think he sucks. I preferred Dane Cook until EVERYONE started "discovering him" and acting like he'd JUST come out. I'm like "WTF, he's been around, YOU just didn't know baout him!"

My personaly favs are:

(used to be...) Dane Cook
George Carlin til he retired.
Robin Williams is alright, but sometimes his cursing gets distracting.
Pablo Francisco is pretty damn funny.
Lewis Black is pretty damn funny.
