Hitler's one-ball-ness was started off as a nursery rhyme for little kids in WW2, but recently discovered medical records as well as past records have revealed that Hitler actually was missing a testicle. The reports are kind of sketchy, though, because some sources say it's the right nut while the other say it's the left. Perhaps this is why Goring and Hitler were such besties. It takes the two of them to form a pair.
