Because she hasn't got arms !
Deaf
Cause she doesn't have arms. Knock, Knock, Whose there Not Sally...
Get off me holmes!
Because someone threw a fridge at her....
Jimmy pushed her... Which is a shame because she was getting used to swinging without arms.
A: Because she has no arms! Knock knock. Who's there Not Susie!
Little Drummer Boy: No Mary: Get out
Everywhere.
