Don't peek at the picture until you read the following: A few days ago I was having some work done at my local garage when a blonde came in and asked for a seven-hundred-ten. We all looked at each other and Bob the mechanic asked, "What is a seven-hundred-ten?" She replied, "You know, that little piece in the middle of the engine, I've lost mine and need a new one." Bob gave her a piece of paper and a pen and asked her to draw a picture of what the piece looked like. She drew a circle and in the middle of it wrote 710. Bob then took her over to another car which had its hood up and asked "is there a 710 on this car?" She pointed to it and said, "Of course, its right there."
