A doctor goes to his office one Monday and is shocked to find that it has been ransacked and the files have all been mixed up. He sees the file for Mrs. Smith, but her chart is mixed up with some of the others and he can't tell which is which.
He finally narrows it down to two charts and he decides to call her house. Mr.Smith answers the phone."Mr. Smith, this is Dr. Jenkins. I have bad news. Your wife either has AIDS or Alzheimer's Disease, I don't know which.
"Well, what should I do?" asks a distraught Mr. Smith.
"Drop her off at the edge of town," says the doctor, "and if she finds her way back, DON'T FUCK HER!"
