Mark a big circle on the floor. This is the pond. The whole group stands around the edge. The leader is the referee. When he shouts "In the Pond," you all jump into the circle. When he shouts "On the Bank," you all jump out. But... sometimes he will try and trick you by saying "On the Pond" or "In the Bank." When he does this, nobody should obey. Anyone who moves, on a wrong order, is out of the game or may pay a forfeit and get back in.
