Miss Susie Had A Baby, His Name Was Tiny Tim

This rhyme has a lot of different variations, but I've included the version that I know below.

LYRICS:
Miss Susie had a baby,
His name was Tiny Tim!
She put him in the bathtub
to see if he could 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.
Miss Susie called the doctor,
Miss Susie called the nurse.
Miss 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’– said the lady
with the alligator purse.
Penicillin said the doctor
Castor oil said the nurse
Pizza! said the lady with the alligator purse
A dollar for the doctor
Two dollars for the nurse
Ten dollars for the lady with the alligator purse
Out went the doctor,
Out went the nurse.
Out went the lady
with the alligator purse.
