This is how I heard it:

Liza, where are you going,
upstairs to take a bath.
Liza, legs like toothpicks
and a neck like a giraffe,raffe,raffe,raffe,raffe.
Liza, stepped in the bath tub,
slipped on a bar of soap
Oh no bless my soul,
There goes Liza down the hole
shshshshshlup

Thanks for the other variants.
