Beware of this problem, it's out there.
A few days ago I was having some work done at my local garage. A blonde came in and asked for a seven-hundred-ten. We all looked at each other and another customer asked, "What is a seven-hundred-ten?"
She replied, "You know, the little piece in the middle of the engine, I have lost it and need a new one." She also replied that she did not know exactly what it was, but this piece had always been there.
The mechanic gave her 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 its hood up and asked; "Is there a 710 on
this car?"
She pointed and said, "Of course, its right there."
