A young doctor had moved out to a small community to replace a
 doctor who was retiring. The older gent suggested the young one
 accompany him on his rounds so the community could become used to
 a new doctor.
 
 At the first house a woman complained, "I've been a little sick to
 my stomach." The older doctor said, "Well, you've probably been
 overdoing the fresh fruit. Why not cut back on the amount you've
 been eating and see if that does the trick?"
 
 As they left the younger man said, "You didn't even examine that
 woman. How'd you come to your diagnosis so quickly?"
 
 "I didn't have to. You noticed I dropped my stethoscope on the
 floor in there? When I bent over to pick it up, I noticed a half
 dozen banana peels in the trash. That was what was probably making
 her sick."
 
 "Huh," the younger doctor said, "Pretty clever. I think I'll try
 that at the next house."
 
 Arriving at the next house, they spent several minutes talking
 with an elderly woman. She complained that she just didn't have
 the energy she once did. "I'm feeling terribly run down lately."
 
 "You've probably been doing too much work for the church," the
 younger doctor told her. "Perhaps you should cut back a bit and
 see if that helps."
 
 As they left, the elder doc said, "Your diagnosis is almost
 certainly correct, but how did you arrive at it?"
 
 "Well, just like you at the last house, I dropped my stethoscope.
 When I bent down to retrieve it, I noticed the preacher under the
 bed."
