Calvin and Hobbes by Bill Watterson for August 28, 1989
Calvin: Mom wants me to make my bed. Come help me, Ok? Hobbes: Ok. Calvin: You get some pencils, and I'll get some big paper! Hobbes: I thought we were making the bed. Calvin: And do all that work?!? No, we're going to invent a robot to make the bed for us! Hobbes: Won't inventing a robot be more work than making the bed? Calvin: It's only work if someone makes you do it.
