710

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 what it was for, but this piece

had always been there. He 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." Please see photo below...
