Not at all the same thing but this reminded me of a trick that was pulled on newbies.
On the destroyer Manley there was a pair of identical twins in the radio shack. Unless you knew them, they looked like carbon copies of each other.
When a newbie comes aboard, there is always some good natured hazing, "Go down to the paint locker for a can of stack gas."
"Go to the Boatswains locker for three yards of water level line."
"Go to After Steering for a jug of relative bearing grease."
Well, these guys had a routine to drive the new kids crazy. A kid would be sent to Radio Central for some BS thing. The duty petty officer would talk to him and say to look in the paint locker. While talking, one of the twins would be nearby, not saying a word.
At the paint locker, the kid would talk to a Boatswain Mate and told to go after steering, with the other twin standing nearby and saying nothing.
They had a routine of ten spaces where there was always one of the twins standing nearby.
Most kids got to the third space and began wondering how that guy was always there before him.
I think only one kid got through all ten spaces without noticing something strange.
