Calvin and Hobbes by Bill Watterson for December 17, 1989
Calvin: 'Tis the season to advertise. Hobbes: Calvin, look! You got a letter! Calvin: A letter? I didn't hear the mail truck. A letter for me? Hobbes: The return address says "North Pole." Calvin: Oh my gosh, it must be from Santa! Santa sent me a letter! Wow! Gee! Hobbes: Read it! Read it! Calvin: "Dear Calvin, you rotten little kid..Oh No!! Santa called me rotten! I'm doomed! Hobbes: Keep reading. Calvin: "I made a list, but I didn't bother checking it twice, because obviously you're the naughtiest kid in the whole world." Augh! Hobbes: What else? Calvin: "I'm writing to give you one last chance. You've got seven days to get on the "good boy" list." Seven days!! Oh no! What can I do?? Hobbes: Maybe he says. Calvin: "I'd suggest you start by being kind to animals. Perhaps you know an animal who would like a snack soon. Or maybe you sholud let an animal read your comic books sometimes. Think about it." Hobbes: Sounds like sage advice. Calvin: "Signed, Santa Claws." Santa Claws? Wait a minute! I recognize this handwriting! It's yours! Santa didn't write this at all!! Give you a snack, huh! How about a knuckle sandwich?! Hobbes: Hmph, well, it's what Santa would've written if he wasn't so busy now.
