A blonde came in to the auto workshop and asked for a seven-hundred-ten thingy. We all looked at each other and another customer asked, "What in the world is a
                     seven-hundred-ten?"

                     She replied, "You know, the part that's right in the middle of the engine, I have lost the one I had and need a new one." She explained that she
                     did not know what it does, but this piece had always been there and she thought she should have it replaced.

                     He gave her a piece of paper and a pen and asked her to draw what it looked like. She drew a circle and in the middle of it wrote 710.

                     Still confused, he then took her over to another car which had its hood up and asked "is there a 710 piece on this car?"

                     She pointed and said, "Of course, its right there..."
