After tripping the light fantastic in Kinshasa, the capital of what was then Zaire, J... returned stateside with a frightening pain in his lower abdomen. In a men's room at McGuire Air Force Base, J... unzipped his jumpsuit to find his scrotum swollen to the size of a peach. No dummy, J... immediately sought treatment from American doctors - the best in the world! - and was nursed back to health with an emergency diet of antibiotics...

But not before his balls had swollen to, in J...'s own words, "the size of softballs."

Fear factor = 2.5 (While genital infections are always worrisome, J... was in fact completely cured, and has gone on to get married and start a family).

Probability of truth = 84.2% (I have independently verified this story with J... himself, and while some important details, such as the name of the virus, are missing, J... confirmed all of the physical details).
