A young doctor moved out to a small community to replace an older doctor who was retiring.

The older doctor suggested that the young one accompany him on his house-call 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. Cut back on the amount you've been eating and see if that does the trick."

As they left, the younger doctor remarked, "You didn't even examine that woman!"
and then asked, "How did you come to the diagnosis so quickly?"

"Ah! 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 has probably been making her sick."

The younger doctor replied, "Pretty clever! If you don't mind, I think I'll try that at the next house."

Arriving at the next house, both physicians spent several minutes talking with a younger woman. She said that she just didn't have the energy she once did and said, "I'm feeling terribly run-down lately."

"You've probably been doing too much 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 doctor said, "I know that woman well. Your diagnosis is almost certainly correct, as she is very active in the church." Then he asked, "But how did you arrive at it?"

"I did what you did at the last house. I dropped my stethoscope and when I bent down to retrieve it, I noticed the pastor under the bed.
