Calvin and Hobbes by Bill Watterson for September 02, 1989
Calvin: Well, Hobbes, we might as well give up. I can't figure out how to make a robot. This one doesn't do anything. Mom: It's past your bedtime, Calvin. You'll have to leave your toys for tomorrow. Calvin: Ok, Mom. Our robot wasn't working out anyway. Gosh, and we spent all day on it, too. I thought for sure our robot would save us from making the bed. Hobbes: And in a way he did! Calvin: Hey, yeah! We're geniuses!
