A doctor is complaining to a mechanic
A doctor is talking to a car mechanic, "Your fee is several times more per hour then we get paid for medical care."

"Yeah, but you see, doc, you have always the same model, it hasn't changed since Adam; but we have to keep up to date with new models coming every month."

A real dilemma
I have this friend who has a real dilemma. His wife won't give him a divorce until she figures out a way of doing it without making him a happy man.
