Recently Volkswagen started a new ad campaign called, PunchDub. The ad shows people punching one another when a Volkswagen Car drives by. Volkswagen has 13 different models to choose from and that is a lot of punching in one drive.
However, the ever-popular road game called Punch Buggy or Slug Bug has the same rules you punch someone when you see a Volkswagen Beetle or a Bug. When you see a Volkswagen Car you punch the person near you and say, “Saw one or There’s one.” When you see a Volkswagen Bug you say, "Slug Bug", and then slug the person closes to you
You as the reader decide which one you prefer. Personally I prefer "Slug Bug" the original game.
