Floppy sock

Equipment: Young people wearing socks (and ideally trousers rather than skirts!)
Stolen from: Matt at Emerge

The players are split into two teams. Each player takes off one sock and takes the other sock only half off, so it flops around. All the players have hands and feet on the floor and assume the crab position (backs nearest the floor, rather than fronts) and the idea is to get the socks off the other team with your hands and feet but without coming out of the crab position. Once players have lost their floppy sock, they're out the game. Last team standing wins.
