Calvin and Hobbes by Bill Watterson for September 16, 1987
Calvin: Hobbes and I are seceding from this family, Mom. Mom: Oh, really? Calvin: Yep. We're taking my sled and moving to the Yukon. Mom: Well, that's a long way away. Calvin: I know. Here's a list of sandwiches and supplies we'll need. Mom: Why should I do all this if you're seceding from the family? Calvin: We haven't seceded yet! Geez. What kind of mom are you?
