Calvin and Hobbes by Bill Watterson for May 26, 1990
Calvin: Boy, I sure got in big trouble today! Mom hit the roof when she found out I just left school. Hobbes: What happened? Calvin: She drove me back and we had to talk to my teacher and the principal! They talked about my study habits, and now I've got extra homework! Hobbes: Ooh. Calvin: And dad is going to check it every night to make sure it's done right! Can you believe it?! So try to do an extra good job now, ok? Hobbes: You're lucky tigers are so smart.
