Skilled Mecahnic

The Gynecologist who became a Mechanic
>
> A gynecologist had become fed up with malpractice insurance and HMO
> paperwork, and was burned out. Hoping to try another career where
> skillful hands would be beneficial, he decided to become a mechanic. He
> went to the local technical college, signed up for evening classes,
> attended diligently, and learned all he could.
>
> When the time of 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 wonder if there is an
> error in the grade. 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.'
>
> After a pause, the instructor added, 'I gave you an extra 50% because you
> did it all through the muffler.'
