Wrong Diagnosis

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.

- Prostrate 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 prostrate 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.
