Greg giraldo and dmitri martin are probably the two that haven't been mentioned yet that I thought I'd mention. Just saw the latter and he did all original material that's all up to snuff.

Not sure if David mitchell's soapbox counts as standup, but I'm obviously gonna plug my man-crush every chance I get. I'd start with his rape and pillage one (don't feel like youtubing, sorry).

The two that are worth repeating for me are Dave chapelle and Louis ck. Good god they are two hilarious human beings.
