A surgeon was relaxing on his sofa. As he settled in for a quiet evening at home, the phone rang. The doctor calmly answered it.

“I’ll be right over,” said the doctor.
As he put on his coat his wife asked, “Is it really serious?”
“Quite serious, it would seem,” said the doctor gravely. “There are already three other doctors there!”
