In stand-up, you do need to be having fun up there, like Richard Pryor said, but you have to know yourself well, too... You start learning, and it's like playing a piano. You know exactly what keys to stroke, 'cause really, with comedy, you're, like, fiddling with people's souls.
I was in love with a lot of people, because I was a student of the game of comedy - Carol Burnett, Jack Benny, Red Skelton, Jackie Gleason, Don Rickles, Red Foxx, Moms Mabley - who gets no credit, Richard Pryor, Bill Cosby, George Kirby. I loved them all, and I used to just take a page out of all of them.
