Calvin and Hobbes by Bill Watterson for February 06, 1989
Calvin: You're taking a shower, now? That means you're going out tonight, right? And you haven't told me to get cleaned up, so that means I'm staying home, right? And if I'm staying home, that means you've gotten me a babysitter, right? And that means you've probably hired Rosalyn, right?!? Mom: Brilliant, Holmes. Calvin: Aaaahhhhhh!
