Calvin and Hobbes by Bill Watterson for July 15, 1989
Calvin: I'm so smart it's almost scary. I guess I'm a child progeny. Hobbes: Most children are. Calvin: Huh? Hobbes: Nothing. Calvin: People think it must be fun to be a super genius, but they don't realize how hard it is to put up with all the idiots in the world. Hobbes: Isn't your pants zipper supposed to be in the front?
