Two Medical Students

Two young medical students were standing on a street corner observing people as they passed and discussing any abnormalities with each other that they may have seen in passers-by. They would then attempt to make the correct diagnosis.

They spotted this old fellow leaving a bar sort of "duck waddling" down the street at a slow pace. The two students introduced themselves to the gentleman and told him that they didn't agree with each others diagnosis of the his problem. One says:

- my friend thinks you have a bad case of hemorrhoids, and I think you have a hernia. Which of us is correct?

The old man replies:

- Well fellas, I thought it was a fart, but it looks like we were all wrong!
