The end of this early interview with Bill Watterson is incredible:

Watterson: Thank you very much; it's gratifying to hear that from people who care about comic art. I never know what to make of it when someone writes to say, "Calvin and Hobbes is the best strip in the paper. I like it even more than Nancy." Ugh.

Christie: That's Andy Warhol's favorite strip.

Watterson: Oh, well, that would figure. Maybe he's the nut writing me.
