A gynaecologist goes to night school to become a mechanic and he is confused by his final mark of 150%. He sees his instructor. “Look,” he says” I don’t want to seem ungrateful but, could you explain how I received such a high score?” The instructor says: “Firstly you were asked to pull the engine apart in an orderly fashion, and for that you received 50%. Secondly you were asked to put the engine back together neatly. For that you received 50%. Finally, I gave you the bonus 50% for doing it through the muffler!”
