Equipment: Per team: sweatpants; jacket; hockey mask; 2 garbage bags.
Divide the group into two or more teams. Line teams up at one end of the playing area, with 1) sweatpants and jacket in front of each team and 2) hockey mask and garbage bags at other end of the area, in front of each team.
On 'Go', the first player of each team puts on the sweatpants and jacket and runs to the other end of the playing area. Here, he takes off the pants and jacket and puts on the mask and skates (the two garbage bags - one on each foot). He 'streaks' back to his team, where he hands over the mask and skates to the next player.
The second player puts on the masks and skates and 'streaks' to the clothes. Here he trades equipment for the clothes and runs back to the third member of the team.
The first team to complete the relay wins.
