WARNING: TZEVETS AND OVER 17s ONLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Sit in 2 concentric circles, facing inwards, so that everyone has a corresponding partner (of similar size is best) in the other circle. Each pair is then numbered, and must remember their number. The gap between then two circles should be roughly 3 or 4 feet (a metre for the metrically minded). One person sits in the middle, and is "in charge". The person in the middle says a number. The person in the inner circle (a) with that number stands up and makes a dash for him/her. The person in the outer circle (b) stands up and ust intercept him. If a makes it to the person in the middle then they take over that position. If b prevents him from getting there then he takes the middle. The person there originally takes over the space of the person who "loses", thus if b catches a, b goes in the middle, a goes to b's original position and the person in the middle goes to a's.
