Everyone wants to know why you don't do a TV show. It's 'cause they're hard, and I'm not curious as to whether I can do it or not. I know I can do it. It comes down to the specifics of who and when and what and where. I did it. I'm not curious. I don't even want my own sitcom. I see my friends that are comedians going in.
