Have players sit or stand in a circle. Choose one to be the leader. The leader nudges the player on his or her left, who nudges the player on his or her left and so on until coming back to the leader.
The leader now tweaks the ear of the player to his or her left, and so on round the circle once more.
For the third and all subsequent rounds, the leader shakes his or her neighbor’s hand, tickles under the chin, blows in the ear, pulls the nose or whatever creative appropriate action that all players will be able to replicate, and so on around the circle. The idea is that the players should perform all these actions without displaying any sign of amusement.
A player drops out of the games if he or she laughs or smiles. The last player left in is the winner.
