When I was in the Navy, I heard about the case of the shipboard “phantom sh*tter”.
An office or such would find a steaming brown pile on his desk.
Everyone figured it was probably some E-1 or E-2 but the irony is it turned out to be a Chief Petty Officer.
Watch “Flight of The Intruder” for a phantom s*****r with a twist. Seems every ship of the line had one.
