Wow, even in the giant list, plenty of my favorites haven't been mentioned...
Steven Wright - genius, pseudo-intellectual humor
Emo Phillips - same as Wright, but more story orientated
Steve Martin - manic creative genius. "Let's Get Small", grandmother's song.
Lenny Bruce - early work, stream of consciousness --
John Mulaney - New in Town (on netflix) - basically clean and funny, the golden combo
jerry seinfield - smaart & generally clean
sara silverman -- funny and smart standup, does good sellf-deluded routine
As mentioned by others: danderfield- No respect, Carlin, cosby
I like smart, creative, insightful & sincere standup. The nasty, cruel, supercool, badass routine bores me.
