Mrs Ward goes to the doctor's office to collect her husband's
test results.
The lab tech says to her, "I'm sorry, ma'am, but there has
been a bit of a mix-up and we have a problem. When we sent
your husband's samples to the lab, the samples from another
Mr Ward were sent as well, and now we are uncertain which
one is your husband's. Frankly, it's either bad or terrible.
"What do you mean ?" Mrs Ward asked.
"Well, one tested positive for Alzheimer's and the other for
AIDS. We can't tell which is your husband."
"That's terrible! Can't we do the test over ?" asked Mrs Ward.
"Normally yes, but Medicare won't pay for these expensive
tests more than once."
"Well, what am I supposed to do now ?"
"The people at Medicare recommend that you drop your
husband off in the middle of town. If he finds his way home,
don't sleep with him."
