“I used to get letters from guys in prison. Anymore now I don't even open them. They'd ask me to please sign a couple of cards for their children. Then I see them on eBay two weeks later. Or the people that write and say, "You is one of my favorite cartoonists. I would like a drawing, please." I guess they encourage inmates to write letters to celebrities. It's like a way to make money by selling autographs or something. Give me a break.”
