"If two plus two equals four every time, what good is it? That's no fun. Why take math? They've figured that stuff out already. Art, literature, how to read this and see it in a different way than somebody else, that I got a shot at. Or how to write this story and tell it in a way that no one else has told it, that I got a shot at. But two plus two will always be four whether I do it, you do it, or somebody else does it, so the hell with it."
—Michael J. Fox, Inside the Actor's Studio (airdate: October 30, 2005)
