Man calls up the doc at 2 a.m. "Doc, my wife is having severe abdomen pain. I think its her appendix."

"What nonsense!" says the doc sleepily.

"I took out your wifes appendix two years ago. Go back to sleep."

Five minutes later, the phone rings and its me again.

"Doc, Im sure its her appendix."

"Oh God!" the doctor groaned.

"Did you ever hear of anyone having a second appendix?"

"No. But Im sure you must have heard of someone having a second wife!!!!"
