Bowling... with people?

Out of all the crazy games we play at camp, Camper-Counselor Bowling is one of the most popular. It involves campers rolling a rubber bowling ball across the grass to knock down the pins... or rather... the counselors! Everybody can play, and everybody gets a spare or a strike. How will the counselors topple? One at a time? With a twirl? It's different every time. It's not hard to see why the campers get such a big kick out of this one - seriously, what's more fun than seeing your counselors get in pin formation and then tumble?
