A doctor is talking to his car mechanic:
“Your fee is much more per hour than what we charge for medical care.”
“Yeah, but you see, doc, you treat always the same model, it hasn’t changed since Adam and Eve, we on the other hand, have to keep up to date with new models coming every year!”

After her surgery a young woman asks the doctor:
“Doctor, how long before I can get back to a normal sex life?”
“Well, madam, it is difficult to answer that, … first time I’ve been asked such a question after tonsil surgery!”
