Calvin and Hobbes by Bill Watterson for June 22, 1992
Calvin: Mom got me some clay! Want to help me make something? Hobbes: Do we get smocks? I want a smock! Calvin: This kind of clay isn't that messy. You don't need a smock. Hobbes: I want a smock! Calvin: Ok, ok, you can have a smock! Hobbes: Let's get a marker and write, "Don't knock my smock, or I'll clean your clock." Calvin: I guess it wouldn't show if dad wore his suit coat.
