I recall a letter, apparently from the RAF CMO, directing a certain student to proceed to the Med Centre as part of a survey of g-suit fitments, which involved the length of his member being taken (by the lady doc) whilst wearing nothing but a g-suit below the waist.
Said student was a tad suspicious, and decided to call the CMO in London direct, to be on the wrong end of a "How DARE you question my orders?" 'conversation', and having his name and unit demanded.
Two minutes later, the CMO is on the phone to Sqn Ops.
"Nice one Lads, what's the story?"
What a player. We sent him a copy of the photo, taken by the guy who leapt from behind the screens as the ruler was being used.
Addendum: Some time later, in preparation for an important visit, the Boss instructed a junior stude to "remove all incriminating evidence" from the Sqn line book. The VIP was, thankfully, amused (and the Boss appalled) to find the picture still there, but with the face whited out with tippex.
