players sit in a circle and
"It" leaves the room.
Designate one player as the leader.
The leader then starts to sway arms, tap foot, scratch head, purse lips....which other players immitate.
"It" is called back into the room and as the group follows the leader, changing from motion to motion, "It" tries to discover who is the leader.
Players try to confuse "It" by looking away from the leader.
When "It" finds the leader, the leader becomes "It" and leaves the room.
