My children learnt the clapping rhyme Hanky Panky in Nigeria and, when they came to England, taught it to all the children in primary school. It went like this -

Down by the river there's hanky panky
Where frogs jump from back to back,
Eeeee, Ooooo,
Eeeee, Ooooo,
Eeeee, Ooooo,
Bad dog.

I think they must have misheard it when they first learnt it and then taught all the kids at primary school the wrong words.
