The doctor must untangle the human knot of arms and bodies!
Choose one person to be the "doctor". Form a circle with the "doctor facing away from the circle (no peeking!). While holding hands the circle, the people in the circle turn and twist and go under and over other players' hands. This make a "knot". Then the group chants, "Doctor, Doctor, we need help." The "doctor" has to untangle the circle without causing anyone to break hands.
