A proctologist had been in practice for 20 years and had settled into a very comfortable life with his future very secure. So he decided to fulfill his REAL dream and become an auto mechanic.
Having entered mechanic school, the former physician received the results of his first test back with a score of 200%. Confused, he asked the teacher why his score was so high.
“Well”, said the teacher, “The first part was taking the engine apart and you did that perfectly, so you got 50%. The second was to put it back together again and you did it perfectly and got another 50%. The other 100% was for doing it through the tailpipe.”
