My mother used to sing the following to us as kids and ( my wife was never impressed) to my twins..., her grandchildren:
A little fly flew past our door
It flew into the grocery store
It peed on the cheese
And babbered on the ham
And wiped its bottom on the grocery man

When the grocery man saw what that fly had done
He loaded up his gatling gun
He chased that fly all up and down
And tried to shoot it up its brown
But the fly was a bit too quick
It showed the grocery man a trick
It flew around the room and then
Went back and babbered on the ham again.

I'm not sure how babber/ babba is spelled but I'm sure you get the drift......
