That's "Susie had a baby", Badhair.
Susie had a baby
she named him tiny Tim
She put him in the bathtub
to teach him how to swim.
He drank up all the water
he ate up all the soap,
He tried to eat the bathtub
but it wouldn't go down his throat.
Susie called the doctor
Susie called the nurse,
Susie called the lady with the alligator purse.
In came the doctor
In came the nurse
in came the lady with the alligator purse.
Mumps said the doctor,
Measles said the nurse,
nonsense (shout) said the lady with the alligator purse.
Shot said the doctor
Pills said the nurse
nonsense (shout) said the lady with the Alligator purse.
(Actually in the one I learned the lady shouted "chickenpox!")
Does this help though? prob not!
