Calvin and Hobbes by Bill Watterson for January 22, 1990
Calvin: Ok duplicates, listen up. As long as you're all here and I don't know how to get rid of you, we might as well cooperate. Specifically, with five duplicates, we can divide up the school week so there's one duplicate for each day. If the rest of us lay low, we can take turns going to school, and no one will be the wiser! Great! Now that still leaves us with the question of who gets the bed tonight. Calvin: We'll fight you for it.
