Got this in a email from my dad today:
Are you missing a 710?
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 the Mechanic 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."
