...the Doctor replied "Of course I won't laugh, I'm a professional.

In over twenty years I've never laughed at a patient."

"Okay then," Bob said, and proceeded to drop his trousers, revealing the
tiniest 'whoo-ha' the doctor had ever seen.
It couldn't have been bigger than the size of a AAA battery.

Unable to control himself, the doctor started giggling, then fell laughing
to the floor Ten minutes later he was able to struggle to his feet and
regain his composure.

"I'm so sorry," said the doctor. "I really am. I don't know what came over
me. On my honor as a doctor and a gentleman, I promise it won't happen
again. Now, what seems to be the problem?"

"It's swollen," Bob replied.

thats hilarious!!!!!
