I was just commenting on George Carlin in another thread, and I thought it'd be cool for us to share thoughts on our favorite comedians.
My list:
George Carlin
Lewis Black
Chris Rock
Mitch Hedberg
Jim Gaffigan
Bill Cosby
Ron White
Bill Engvall
John Cleese (and the rest of Monty Python)
Amongst talk show hosts, I like Jon Stewart, David Letterman, Conan O'Brien, and Bill Maher.
I'm sure there are others that I'm omitting, as this is off the top of my head.
I hear so much about Lenny Bruce and Richard Pryor that I really want to get a hold of their stuff. I feel like I'm missing out.
