The Rules: If you see a Volkswagen Beetle, call out "Punch Buggy, [color of vehicle]!" This earns you one punch on another player. Be sure to follow this up with "No punch backs!" or you will be punched back. Also Known As: "Slug Bug."

Here is a game that follows in the grandest tradition of children's backseat pastimes: using any excuse to inflict violence on your fellow man. There are numerous variations on this game. For example, sometimes the punch-causing object is a car with one headlight out. In that case, the game is called "spadiddle" or "paddidle." We bet a version of this game has been played with any relatively rare road trip sight, as, again, humans will use any excuse to hit each other.
