A doctor gets a phone call at the middle of the night.
A hysterical man says: "I'm Mr. Jones, please come fast! My wife has a horrible pain in her abdomen. I think it is appendicitis."
"Calm down, Mr. Jones, and go back to bed." says the doctor "I have taken out your wife's appendix last year. And I have never heard of a case where an appendix would have grown back."
"Doctor", says the now offended gentleman "and have you heard of a case when someone got remarried?"
