Stupid Submariner Tricks
One time when I was a JO, I went on leave with the reactor safety keys. I'd gotten relieved as EDO and signed out on leave, and drove home without turning over the keys. When I got home, I heard the phone ringing inside, and as I reached into my pocket to get the keys, I felt the lanyard and thought, "I bet I know what that call's about." (There was an RC entry planned for that day). Had to turn around and head back to the boat.
