A gynecologist had become fed up with malpractice insurance and was on the verge of being burned out. Hoping to try another career where skilful hands would be beneficial, he decided to change careers and become a mechanic. He found out from the local technical college what was involved, signed up for evening classes, attended diligently, and learned all he could. When the time for the practical exam approached, the 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 obtained a score of 150%. Fearing an error, he called the instructor, saying, "I don't want to appear ungrateful for such an outstanding result, but I wondered if there had been an error which needed adjusting.

"The instructor said, "During the exam, you took the engine apart perfectly, which was worth 50% of the total mark. You put the engine back together again perfectly, which is also worth 50% of the mark." The instructor went on to say, "And I gave you an extra 50% because you did all of it through the muffler."
