Atlas Obscura shared this family jewel about a "scrotum concealment device, developed to be worn on the human body. It was designed to hide a miniaturized escape radio, with the idea that enemy officers would never think to thoroughly search the genital area."
Don't get your balls too twisted with excitement, though — the artificial radio scrotum never got any action in the field, and instead languished away in someone's desk for years, presumably getting some occasional use for inappropriate office pranks.
