A guy takes his wife to the doctor. She's been sick lately...losing weight, and very confused mentally. The doctor runs a whole bunch of tests and says he'd call the couple in a week with the results.
A week goes buy and no word from the doctor so the husband gives him call. The doctor tells the husband he has misplaced the test results can't remember if the diagnosis was AIDS or Alzheimer's.
The husband is obviously perplexed and asks the doctor what the hell he should do.
The doctor replies "Drive her 10 miles out of town and kick her out of the car. If she makes it back home don't sleep with her."
