|Doctors are used to getting calls at any hour. One night a man phoned his doctor, waking him up.|
"I'm really sorry to bother you so late," he said, "but I think my wife has appendicitis."
Still half asleep, the doctor reminded him that he had removed hs wife's inflamed appendix a couple of years before.
"Whoever heard of a second appendix?" the doctor asked.
"You may not have heard of a second appendix, doc," the man replied, "but surely you've heard of a second wife!"
