Best with 2 teams although can be played using 4.
Teams line up, single file, equal distances from the leader who stands arms outstretched towards the teams. At command players jump legs astride with the exception of the team member at the back who must crawl through the tunnel formed by the legs. Once at the front they stand up and the next team member crawls through the tunnel. This continues until one of the teams can touch the outstretched hand of the leader. To avoid cheating team members must be able to touch the shoulders of the person in front.
