A few days ago I was having some work done on my car at a local
garage when a blonde came in and asked for a seven-hundred-ten.
We all looked puzzlingly at each other, and another customer asked
"What is a seven-hundred-ten?"
The reply was: "It's the little piece in the middle of the engine.
It had always been there, but I have lost it and need a new one."
When given a piece of paper and a pen and asked to draw what the part
looked like, the blonde drew a circle and in the middle of it wrote "710".
When taken over to another car which had its hood up and asked "Is there a
710 on this car?", the blonde pointed and said "Of course, it's right there."
