Converting a gynecologist to a mechanic

A gynecologist decides that he'd had it with gynecology. He wanted to go and fulfill his lifelong dream and become a car mechanic. So he studied hard, and when he felt he was ready, he registered to go take the state licensing test.

The results of the test arrived a few weeks later, and with trembling hands he opened the envelope to discover that he passed with flying colors! He got a score of 200 points out of the 100 points possible. "200 points out of 100 points possible?" he asks himself. "How can that be?"

So he calls the licensing board and they tell him: "You see sir, you received 50 points for taking the engine apart perfectly, 50 points for putting the engine back perfectly, and 100 EXTRA points for doing it all through the exhaust."
