Ding-Dong Don't Ditch
Basically the exact same game as knock and don't run but with a much better name. You knock on someones door and insist that they are the one knocking on yours, made famous in NH by Tyler Malachow.
Paco-One of these days i wish to have half the balls of Malachow, he plays Ding-Dong Don't Ditch like a champ.
