Margaret Cho and Janeane Garofalo.
Five years ago.
I've even kind of been disapointed by Cross lately... his politics are getting in the way of the humor.
Patton Oswalt is hands down my favorite right now.
Zach G. is also just brilliant.
I think Paul F. Thompkins is also totally underrated. He changes his material faster than anyone else I've seen more than a few times... he keeps it good too.
