Calvin is doing his homework. He tells Hobbes Mom won't let him go outside until he finishes. He suggests Hobbes help him so he can get done faster. He asks Hobbes what five plus seven is. Hobbes doesn't know, nor does Calvin. Hobbes suggests he write "I don't know" as the answer. Calvin agrees that's a true answer. He can write that for all the questions. He's done. Out the door he and Hobbes go. Inside the house, we hear someone saying they're going to have a look at their prodigy's homework.
