Haven't seen much of his other stuff but Robin Williams Live on Broadway was the funniest stand up ever.
I also like Chris Rock, old Steve Martin stuff and some really old stuff such as abbot and costello.
that shit gaffigan does when he does the high pitched voice and pretends to say the thoughts of the audience out loud while he is doing his routine is classic; i lole every time.
Lewis Black, George Carlin, Mitch Hedburg, Stephen Wright, Demetri Martin, Zach Gafalankus, David Cross, Patton Oswalt, Daniel Tosh,and Richard Jeri to name a bunch

and I love all you nonconformists who say dane cook isnt funny hes fucking hilarious
wow did you really just say that Dane Cook was not only equal to, but greater than Carlin and Hedberg? seriously dane cook is sooo overrated and no one is better than carlin or hedberg
