A blonde entered her local garage and asked the mechanic behind the front desk for a seven-hundred-ten. The mechanic looked at her confused and 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 explained 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, it's right there."
