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 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."
This is what she pointed to...
