Calvin and Hobbes by Bill Watterson for August 11, 1988
Calvin: Hobbes, quick! How do you turn off the water?!? Hobbes: How should I know?? Calvin: I can't put this piece back in with all this water coming out! Hobbes: I'll get your mom! Calvin: My mom? Have you lost your mind?? She can't find out about this! Hobbes: I'll bet she notices when the kitchen ceiling starts to drip. Calvin: Open the medicine cabinet! Find some cyanide!
