The Naked Ninja is similar to our own Phantomstreaker, a mystical creature who would appear at random formal functions from behind a curtain or side door. He would run stark naked balls and all through the said function wearing only a Zorro typeface mask.
The alleged guilty suspect would of course at the next function be in full conversation with the WO and SENGO who would scream blue murder that they thought you were the guilty airman.
Final appearances could be seen at RAF Cosford in the Cpls Club leaning naked against the bar with a pint.
Rumours have it he still comes out of retirement at Bruntingthorpe from time to time.......
