"Now, don't laugh!" said Ed to his doctor.
"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," Ed said, and proceeded to drop his trousers, revealing the tiniest little willy the doctor had ever seen. It couldn't have been any bigger than the size of a AAA battery.
Unable to control himself, the doctor started giggling, then fell to the floor, laughing uproariously. Ten minutes later, he was finally 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 gentlemen, I promise it won't happen again. Now, what seems to be the problem?"
To which Ed replied, "It's swollen."
HAHAHAAAAHAHAHAHAHAAAA HA (deep breaths) HAHAHAAAAAAAAAAAA
