Calvin and Hobbes by Bill Watterson for October 31, 1989
Calvin: I think we've got enough information now, don't you? Hobbes: All we have is one "fact" you made up. Calvin: That's plenty. By the time we add an introduction, a few illustrations, and a conclusion, it will look like a graduate thesis. Cesides, I'be got a secret weapon that will guarantee me a good grade! No teacher can resist this! Hobbes: What is it? Calvin: A clear plastic binder! Pretty professional looking, eh? Hobbes: I don't want co-author credit on this, Ok?
