Diagnosis

A woman takes her husband to the doctor, as he had recently been acting quite ill. The doctor examines the man and calls the woman in to tell her the diagnosis.

The doctor says, "Well, Madam, he's either got AIDS or Alzheimer's."

The lady replied, "How can I tell which one he has?"

"Take him out into the woods and drop him off. If he comes home, don't fuck him."
