Over Under

Have two teams stand in a line all facing the back of the person in front of them. Give the first person in the tow a ball and have them pass it over their head, backward to the person behind them. That person, in turn passes it though their legs to the person behind them and the ball gets moved down the line very quickly this way. Then the person at the back, upon receiving the ball runs it to the front of the line and becomes the first person and starts the process all over again. This goes on until the original starting person of one team is back at the front.
