I learned this:

Alice, with legs like toothpicks
And a neck like a giraffe
Alice, went to the bathroom
Upstairs to take a bath
Alice, got in the bathtub
Alice, pulled out the plug
Oh my goodness, oh my soul, there goes Alice, down the hole
Alice? Alice! [Glug, glug, glug.]

And that was all. Nothing to do with the duck may be somebody's mother.
