Assembly Required

A gynecologist tired of his profession, and wanting less responsibility,
decided a career change was in order. After some serious thought, he decided
that being an engine mechanic, something he had once enjoyed prior to college,
would be a good choice. However, it had been a long time since he had tinkered
with an engine and he knew that in order to compete with the younger workforce,
he would have to go to school.
He enrolled in a technical institute that specialized in teaching auto
mechanics. He aced the course, but the final exam required each student to
completely strip and reassemble an engine. It was with some trepidation that he
took the test. At completion, he turned the engine over to his instructors for
evaluation and awaited his final grade.


When they were handed out, he did a double take at the 150% grade he received.
Rather confused, he asked his instructors how it was possible to have a grade
like this.
