Appendectomy

Five year old Becky answered the door when the census taker came by. She told the Census taker that her daddy was a doctor and wasn't home, because he was performing an appendectomy.

"My," said the Census taker, "that sure is a big word for such a little girl. Do you know what it means?"

"Sure, fifteen hundred bucks, and that doesn't even include the anaesthesiologist!"
