Big Bob, a strapping lad standing 6ft 5 went to his local Doctor and said, "Doctor, I've got a problem, but if you're going to treat it, first you've got to promise me, and I mean it - not to laugh."

"Of course I won't laugh," the doctor said. "I'm a professional. In over twenty years I've never laughed at a patient. And you're a mighty big fella for anyone to be laughing at!"

"Okay then," Bob said, and proceeded to drop his trousers, revealing the tiniest peni$ the doctor had seen in all his years. Unable to control himself, the doctor fell laughing to the floor. Ten minutes later he was able to struggle to his feet and regain his composure.

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

"It's swollen!"
