A man went to the doctor and said, "Doctor, I've got a problem, but if you're going to treat it, first you've got to promise 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."
"Okay then," the man said, and proceeded to drop his trousers, revealing the tiniest pecker the doctor has ever seen. Unable to control himself, the doctor had to resort to coughing to hide his laughter. A couple of moments later when the ‘coughing fit’ had passed he was able to regain his composure. "I'm so sorry," he said. "I don't know what came over me. On my honour as a doctor and a gentleman, I promise it won't happen again. Now what seems to be the problem?"


"It's swollen."
