Calvin and Hobbes by Bill Watterson for February 20, 1991
Calvin: Look, I've got some modelling clay! Hobbes: What are you making? Calvin: This is a hoof. Hobbes: A hoof? Calvin: Right! This will be a life-size equestrian statue of me! Hobbes: A new Horseman of Apocalype, hmm? Calvin: I think I'm going to need more clay.
