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." Click here to see
a picture of what she pointed to.
