these are the games i know where you stand in a circle and your right hand is on top of the person on your right and your left hand is under the person on the left and you go around in a circle slapping hands:
(this is my favorite)
down by the banks of the hanky panky where the bullfrogs jump from bank to bank
singin east side west side
kerrrrrplop!!
(the reason i think that it was originally east side west side is cause thats where the bullfrogs jumped, doesnt that sound right?)

i also know:
slap-diddly o so slap slap slap
talariko riko riko riko
flo flo flo flo falo faaaalo
1,2,3,4!!

and:
my little crakerjack crakerjack he said she said
jimmy jimmy jack jack
flo flo flo flo falo faaalo
1,2,3,4!
