This Activity is meant for Cub Scouts.

Scouts stand in single file.
Each scout reaches down between his own legs with his right hand.
Each scout grabs the right hand of the scout in front of him with his left hand.
On 'GO', the front scout walks backwards, straddling all the scouts in line. As he does this, he is pulling the 2nd scout who does the same thing.
When the last scout is pulled to standing, the snake is skinned and the patrol gives a yell.
