The phone rings and the lady of the house answers.  “Hello.”

“Mrs. Sanders please.”

“Speaking.”

“Mrs. Sanders, this is Dr. Jones at St. Agnes Laboratory.  When your doctor send your husband’s biopsy to the lab yesterday, a biopsy from another Mr. Sanders arrived as well, and now we are uncertain which one is your husband’s.  Frankly, the results are either bad, or terrible.”

“What do you mean?” Mrs. Sanders asked nervously.

“Well, one of the specimens tested positive for Alzheimer’s and the other one tested positive for AIDS.  We can’t tell which is your husband’s.”

“That’s dreadful!  Can’t you do the test again?” asked Mrs. Sanders.

“Normally, we can, but Medicare will only pay for these expensive tests one time.”

“Well,” she went on, “what am I supposed to do now?”

“The people at Medicare recommend that you drop your husband off somewhere in the middle of town.  If he finds his way home, don’t sleep with him.”
