Man goes to see a doctor and tells him he has a problem with his private parts, but the doctor must promise not to laugh...

The doctor gets real indignant and assures the man he is a professional and has never found a patient funny.

The man drops his pants, and there it is, about the size of a peanut, as hard as the doctor tries he can't stop himself and bursts out laughing,

He composes himself, apologizes many times and asks "what seems to be the problem?"

The man answers "It's swollen"

OMG!
