Calvinball and the Art of Changing the Rules

Who here has played Calvinball, or its equivalent? This is the famous game played by Calvin and Hobbes where they constantly change the rules. Playing a game where the only rule is who can change the rules to their advantage can seem fun at first, but in time, it really becomes exhausting. If you have ever played games with a grade school boy, you might have experienced this and it can be difficult to keep up.
