Calvin and Hobbes by Bill Watterson for December 16, 1987
Calvin (writing): Dear Santa, attached is my christmas list for this year. Last year I did not receive several items from my list. For your convenience, I have grouped those items together on page 12. Please check them carefully, and include them with the rest of my loot this year. Calvin: That's the problem with this guy. He's gotten sloppy without any competition.
