and a clapping game I learned at girl's camp I would say hmmm mid 90's I think, in the same area. We would sit in a circle with one hand resting palm up under our neighbors' hand and going around the circle slap our neighbors' hand

Down by the banks of the Hanky Panky
Where the bullfrogs jump from bank to banky
Singin' e-i-o-u
Um sacka dilly wacka...ker-plop

whoever had ker-plop! was eliminated from the circle and it would be speeded up.
