Yesterday I was having some work done at the car dealer. A blonde
woman came in and asked for a seven-hundred-ten.

They all looked at each other, and one of the mechanics asked, "What is
a seven-hundred-ten?"

She replied, "You know, the little piece in the middle of the engine.
I lost it and need a new one. It had always been there."

The mechanic gave the woman a piece of paper and a pen and asked her to
draw what the piece looked like.

She drew a circle and in the middle of it wrote 710. He then took her
over to another car which had the hood up and asked, "Is there a 710 on
this car?"

She pointed and said, "Of course, it's right there."
