A lab tech calls Mrs. Jones and says to her, "I'm sorry, ma'am, but there has been bit of a mix-up and we have a problem. When we sent the samples from your husband to the lab, the samples from another Mr. Jones were sent as well and we are now uncertain which one is your husband's.

Frankly, it is either bad or terrible!"

"What do you mean?"
"Well, one Mr. Jones has tested positive for Alzheimer's and the other for AIDS. We can't tell which is your husband."

"That's terrible! Can we do the test over?"

"Normally, yes. But your Doctor's practice has a tight budget, and they won't pay for these expensive tests more than once." "Well, what am I supposed to do now?"

"Your doctor recommends that you drop your husband off in the middle of town. If he finds his way home, don't sleep with him."
