A gynecologist was fed up with malpractice insurance and HMO paperwork. Hoping to find another career where skillful hands would be beneficial, he decided to become an auto mechanic.

He went to the local technical college, signed up for evening classes, attended diligently, and learned everything he could.

When the day of the final, hands-on practical exam approached, the gynecologist felt ready. He had prepared carefully for weeks, and figured that he knew as much about motors and engines as he possibly could. After taking the test, he was surprised to learn that received the top score in the class: a whopping 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's been an error in my final grade?"

"The instructor answered, "During the final exam, you took the engine apart perfectly, which was worth 50% of the total mark. You reassembled the engine perfectly, which is also worth 50% of the mark."

The instructor paused, then added, "I gave you an extra 50% because you did it all through the muffler, which I'd never seen done before!"
