A gynecologist had become fed up with high cost of malpractice insurance and was on the verge of being burned out. Hoping to find another career where skillful hands would be beneficial, he decided to make a major career change and become a Harley mechanic. He found out from the local community college what was involved, signed up for the classes and learned all he could. When the time for the practical exam approached, the former gynecologist prepared carefully for weeks and completed the exam with tremendous skill. When the results came back, he was surprised to find that he had scored 150%. He called the instructor, saying "I don't want to appear ungrateful for such an outstanding result, but I wondered if there was an error." The instructor said, "During the exam, you took the engine apart perfectly, which was worth 50% of the total mark. You also put the engine back together perfectly, which is also worth 50% of the mark." The instructor went on to say, "I gave you that extra 50% because you did all of it through the muffler."
