A man was walking along a sidewalk in a very gentle manner, almost as
if he
were walking on eggs. Two doctors, also on foot, were across the
street. They
spotted the man and began to discuss his condition.
"Prostate trouble," said the first doctor.

"Oh no, not at all. That's a case of hemorrhoids if ever I saw one",
said the
other.

They tossed it back and forth until one of them suggested going over to
talk
to the man.

"Mister, this gentleman and I are both doctors," said one, "and if
you'll
pardon our intrusion, I figured you have a bad prostate problem, but
my
colleague thought it to be hemorrhoids. Might you state the problem so
that
we can solve our little dilemma?"

"Well", said the man, "all three of us were wrong. I thought it was
gas."
