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 serious condition
A well respected surgeon was relaxing on his sofa one evening just after arriving home from work. As he was tuning into the evening news, the phone rang. The doctor calmly answered it and heard the familiar voice of a colleague on the other end of the line."We need a fourth for poker," said the friend."I'll be right over," whispered the doctor. As he was putting on his coat, his wife asked, "Is it serious?""Oh yes, quite serious," said the doctor gravely."In fact, three doctors are there already!"
