Dice is the all time favorite. Aside from the "big" names like Pryor, Murphy, Carlin etc... the first comics that I enjoyed were Bobby Slayton and Bobcat Goldthwait (when his act was mostly screaming non-sequiturs). These days I'm listening to Jim Norton a lot - especially the Chip Chipperson stuff, Legion of Skanks (Big Jay Oakerson, Luis J Gomez & Dave Smith), Dean Delray, Ari Shaffir, Artie Lange, Dave Attell, Dan Soder, Mark Normand, Rich Vos, Bonnie McFarlane and Kim Congdon.
