710

A few days ago I was having some work done at my local garage. A blonde came in and asked for a 710. We all looked at each other and another customer asked:
- What is a 710..? She replied,
- You know, the little piece in the middle of the engine, I have lost it and need a new one...
She said 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.
