Nah... nothing to do with babies.. at least not the one my classmates yelled at me when I was in 12th grade, 5'9" tall, 102 lbs (American that is)... and this version is short:

"Anna May, where are you going"
"Upstairs to take a bath."
Anna May with legs like toothpicks,
A neck like a giraffe.
Anna May gets in the bathtub,
Anna May pulls out the plug,
"O my goodness, o my soul!
There goes Anna May, down the hole!
Anna May! Anna May!"
"Glug"

The happy ending is that when I was 17 a photographer saw me, took some pictures, and lo and behold! whew.. became a New York photographer's fashon model for a few years!
(No, don't ask my age now. I like and lie and lie.. lolol)
