Calvin and Hobbes by Bill Watterson for September 20, 1990
Calvin: Boy, I feel sharp! I know this math stuff cold! I'm ready for anything! I hope the teacher calls on me! I hope I get to demonstrate a problem at the board! I'll impress everyone! Miss Wormwood: Here, Susie. Take one sheet and pass the rest across. Susie Derkins: What's this? Miss Wormwood: A math quiz.
