Rubber Dolly

I never could jump rope worth a darn - couldn't do it if the rope was lying on the ground - but I woke up this morning with jump rope songs/chants skipping through my head.
"Not last night, but the night before..."
"Mary and Tommy sitting in a tree..." 
and-
My Mother told me
If I was goody
That she would buy me
A rubber dolly
My Auntie told her
I'd kissed a soldier

Now she won't buy me

A rubber dolly.

Turns out that last one may or may not have had anything to do with jumping rope.  It's an old bluegrass fiddle tune that often accompanied buck dancing.

Did you ever jump rope to "Rubber Dolly?" 

I never did, but, like I said, I couldn't jump rope to anything.
