The phone rings. The lady of the house answers, "Yes?"
"Mrs. Ward, please."
"Mrs. Ward, this is Doctor Jones at the Medical Testing Laboratory.When your Doctor sent your husband's samples to the lab, the samples from another Mr. Ward 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?" Mrs. Ward asks.
"Well, one Mr. Ward has tested positive for Alzheimer's disease (related to memory) and the other for AIDS. We can't tell which your husband's is" "That's terrible! Can we do the test over?" questions 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."
