Well, there is one I am surprised they missed...

Ring-a-round the rosie, was the village children's chant when the set fire to a witch.

And here is a neat one from America...

On the plantations, when they slaughtered a pig, the field hands got the feet and the hamhocks and the tail....the folks in the big house got the hams and the bacon...thus they were livin' "High on the Hog".
