This is what I remember about Dodge Ball, one of the most fun co-ed games we played back then. The X's and the O's in the above graphic represent the opposing teams, one outside of a circle enscribed on the ground. The object? For the "X" team to fire away at the "O" team in the circle, attempting to eliminate them one by one, as the ball hit them. The "O" team would obviously try to survive by dodging the ball. The last person standing was obviously the best dodger. When and if the "O" team was eliminated entirely, the teams would switch sides. Hey, are you guys still in shape for a game?
