Calvin and Hobbes by Bill Watterson for August 10, 1987
Calvin: Hobbes, did you hear? Mom and Dad are taking us camping! We get to live in a tent and go fishing and canoeing! Won't that be fun?? Hobbes: We'll be roughing it! Living off the land! No TV or radio or... Calvin: Uh-oh. Hobbes: What's wrong? Calvin: This sounds suspiciously like one of Dad's plots to build my character.
