A chap takes his missus to the doctor...
to get some tests done. The results come back and the doctor looks rather confused.
"Sir, it's bad news I'm afraid. We're not quite sure if your wife has AIDS or Alzheimers"
Shocked, the man asks "Well, what, in your medical opinion, should i do?"
"There is only one thing for it" explains the doctor.
"Drive her into the town centre, leave her there and if she comes home, whatever you do, dont fuck her"
