A cheetah went into a garage and asked for a seven-hundred-ten. We all looked at each other and another customer asked, "What is a seven-hundred-ten?" He replied, "You know, the little piece in the middle of the engine, I have lost it and need a new one..." He said he didn't know exactly what it was, but this piece had always been there. The mechanic gave him a piece of paper and a pen and asked him to draw what the piece looked like. He drew a circle and in the middle of it wrote 710. He then took him over to another car which had its hood up and asked, "is there a 710 on this car?" The cheetah pointed and said, "Of course, it's right there."
