Calvin and Hobbes by Bill Watterson for July 12, 1986
Calvin: Dad, look! I caught a fish! Dad: Hey, that's a big one. I'll show you how to clean it, and we'll have it for dinner. Calvin: "Clean it"? Dad: Cut off its head and gut it. Calvin: Mmm! Pass me another of these great cheese sandwhiches! Ha ha. No bones in these, right?
