One of my 2nd graders taught a hand clapping game in our music class in Abilene, Texas 5-30-08.

Down by the bay, by the bay, the bay,
Where the bullfrogs jump from bay to bay,
Where the eeps, ahps, ohps, ahps
Bowl fulla jelly and a ker-plop.

The children stand in a cirle with hands extended palms up. The right hand is on top of the one to the right and the left in beneath the one to the left. The beat is passed around clockwise as the players slap their neighbor to the left. On 'plop' they must hit the neighbor's hand before it is pulled away. If you hit your own hand, you're out. If you hit the neighbor's hand, he is out. The last two standing lock fingers and "saw" to the beat and tug on plop like tug of war. The one who pulls someone over the line is the winner.
