Doctor and nurse jokes

A pipe burst in a doctor's house. He
called a
plumber. The plumber arrived, unpacked his tools, did
mysterious plumber-type
things for a while, and handed the doctor a
bill for $600.

The doctor exclaimed, "This is ridiculous! I don't even
make that
much as a doctor!

."
The plumber quietly answered,
"Neither did I when I was a
doctor."
