A Gynecologist

A gynecologist who had lost interest in his medical practice decided to change careers and enrolled in auto mechanic school. 
He performed well in the course but was still shocked when he got an off-the-chart 200 on his final exam. He asked the instructor to explain the grade.
"I gave you 50 points for taking the engine apart correctly," the teacher said, "50 points for putting it back together correctly -- and an extra 100 points for doing it all through the muffler."

A Pregnant Woman

A pregnant woman went to the gynecologist, and when asked that was the problem, she responded, "Well, whenever I take off my clothes, my nipples get hard."

Shocked, the doctor took a deep breath, then asked, "Your nipples get hard?" 

"Yes" quite innocently came her reply. 

"Undress so I can check" replied the still amazed doc. 

So, she undressed, and he got down to the feeling and massaging, trying to reach an answer.

After some considerable time, the doctor, still looked puzzled, said, "Well madame, I don't know what you have, but it sure as hell is contagious!"
