She's 12 now, Alison, and learned the song when she was 9 from a friend on the playground. I asked her when I drove her to school, and she had this much more:

When Susie was a teacher
A teacher Susie was
She hit us with a ruler
And gave us great big welts
Call the operator
Give me number nine
Tell Susie not to hit us
And now our hands are fine

And she had Suzie losing her bra as a granny (wonder who misheard that one and what the transition was) "at a party in her boyfriend's car".
Blessings,
Barbara
