The phone rang. 
 The lady of the house answered. "Yes?" 
 "Mrs. Ward, please." "Speaking" 
 "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 asked. 
 "Well, one Mr. Ward has tested positive for Alzheimer's and the other 
 for AIDS. We can't tell which your husband's is." 
 "That's terrible! Can we do the test over?" questioned 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."
