A
game often played by
children under the direction of
adults (it requires someone who isn't playing to control the
music).
Start with a group of players and a number of chairs (at least one fewer chairs than players). Turn some music on; the players all walk around the chairs while the music plays. At some random moment, the person controlling the music will turn it off and all the players will dive for chairs. The last person not sitting in a chair is out for that round. Then you take away at least one chair and start over, repeating until only one chair is left; the person sitting in it wins the overall game.
(Or you could do it like Bart Simpson's remedial class in one episode, where there were more chairs than players so no one was ever out.)
Tem42 suggests "It might be interesting to note that given the three standard rules of 1. no passing 2. no pushing and 3. no going backwards, that this is one of the few games to favor the slower children. Walking slower than the person in front of you means there are more chairs ahead of you. The faster, impatient children cut off their options by crowding the others."
