Roxie's favorite song

A few weeks ago, the girls fell asleep in the car on the way home from someplace and I was carrying them into their beds. Roxie woke up while I was carrying her and demanded that I sing her a song.

I started up: "Rockabye baby, on the treetop..." Apparently this wasn't to her liking. "No, no! My other favorite song."

Not knowing what she wanted, I tried something I had heard her singing to herself several times in the past:

One little girl
Jumping on a log
Her falled down and broke her arm

She fell asleep and I put her in bed.
