From northern Missouri about 1993 or so:

Down by the banks of the hanky panky
where the bullfrogs jump from bank to banky
saying e a-poppa, i a-poppa, o a-poppa, POW

It was the circle elimination game with slaps coming on each beat until the last, and that person was out. When you got to two players you grabbed hands and pushed back and forth with every beat until the POW and whoever's arm was extended with the pow won.
