Seat the boys in a circle. Warn them to maintain a serious expression. Someone stands in the center of the circle and smiles, then wipes the smile from his face and tosses the smile to someone in the circle calling their name so that there will be no mistake. The "Smile Catcher" must put on the smile, wear it for a moment, "wipe" it off and pass it to another boy. The boy that does not wipe the smile off completely, or smiles out of turn, must stand up. Since smiling is contagious, the entire group will soon be standing…as well as smiling!
