Players: small to large groups
Teams competing lay down side by side on floor or ground. The first person lays back of hand on next persons stomach and that person lays back of hand on the stomach of the next to him and so on.
The first person in line has to laugh one “HA”. The next person in line has to laugh “HA HA” (two times). The third person has to laugh “HA HA HA” (three times). And so on.
Any person that breaks out into a giggle is out of the game and must get up and the hole is filled in. The last one to giggle, wins.
