Man goes to his wifes Doctor to get the results of a test she took last week. Doctor says " Mr. Smith, there has been a mixup. We had TWO Mrs. Smiths in on the same day, and when the results came back we aren't sure which one is your wifes, and which one belongs to the other Mrs, Smith."

"Oh my, says Mr. Smith. Was the news good or bad?"

The Doctor says " One was very bad, and the other was terrible. One Mrs. Smith has Alzheimers, but the other one has AIDS."

"Can we run the test again?", asks Mr. Smith. "No, we can't," says the Doctor. "Your Blue Cross will only pay for one test."

"Well then, what should I do?" asks Mr. Smith.

Doctor says " We suggest you drive your wife out into a strange part of town and drop her off. If she finds her way home, DON'T MAKE LOVE TO HER."

Last line cleaned up for mixed company.
