No Laughing Matter

A guy goes to see a doctor and when they get into the private room the doctor says to the patient, "What seems to be the problem?" The patient answers, "You have to promise not to laugh."

The doctors said fine, and the patient pulls down his pants and the doctor tried not to laugh at his small penis.

The doctor managed to ask, "What's the problem?"

The patient then said, "It's swollen."
