Greetings to All:
There is an old Military Prank that I have only seen done once and that was when I was with the Army Cadets.
A Brand New Recruit is coerced by his Peers into thinking that he is in need of his 'M1 Papers' along with his other Comrades who have already gotten theirs.
So the Recruit then goes to the Sergeant and puts in for a copy of his 'M1 Papers'.
On the next Parade, the Recruit is called forward to get his Masturbation First Class Papers.
I saw this done when I was in the Army Cadets in about 1979.
