The game of punch buggy has evolved in our family to require announcing the color of the Volkswagon that you are claiming before you slug someone. Sometimes, we just blurt the color before inflicting the punch. IF you are sitting at a red light and a green VW cruises past you, THEN you should not shout “green” and punch your spouse. Doing so MIGHT result in said spouse lunging into the intersection while the light is still red. Of course, I’m just guessing that this is what could possibly happen. I would never do such a thing to my over-caffeinated husband. Well, I would never do it again.
