Dave Chappelle, heck yea. Blue Collar was good, when it was alil taste of all of them together and they feed off of each other well. Seperate them though, they get old fast.
My top 5 (in no particular order)…
George Carlin
Dave Chappelle
Dane Cook
Mitch Hedberg
Brian Regan
Other mentionables… Richard Pryer, Pablo Fransico, and others who I can’t think of at the moment.
But uhhh… if you like impressions, try these two.
