A gynecologist had become fed up with malpractice insurance and was on
the verge of being burned out. Hoping to try another career where
skillful
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%. The instructor went on to
say, " I gave you an extra 50% because you did all of it through the
muffler."
