Calvin and Hobbes by Bill Watterson for March 31, 1991
Susie: Uh oh, here comes Calvin. The incurable weirdness poster child. Hi Calvin. What's with the mask and bucket? Calvin: Hmph. This is a poem! Please do what you're told! And here is a bucket of water, ice-cold. Please take this water, and dump it on me! Don't hesitate! Do it A.S.A.P. Just wait till you touch the "pernicious poem place"!! Ooooh you'll be sorry then! Hobbes: Wheee! I love playing Calvinball! This is a bag flag zone!
