As a companion to the Hall Of Shame thread, here's a more positive take; who are the stand up comedians that really do it for you, past and present??
Here's a few for me:
Steve Martin
Especially his Lets Get Small album.

Louis CK
Pumps out an entirely new hour show every year, a brilliant comic.

Eddie Izzard
Definite Article in particular. I used to watch his stuff over and over in the nineties.

Stewart Lee
Smart, fearless, funny.

I've heard plenty of good stuff about Patton Oswalt too, and I've just bought one of his albums to have a listen.
