On many U.S. Navy ships the movie screen is suspended amid-ship so that it can be viewed from both sides. This procedure makes it available to larger crowds at popular movies, but usually the junior officers get a reverse image from 'the wrong side of the screen.'
One evening at dinnertime an enterprising young ensign passed the following word over the officers' IMC circuit: "The movie to be shown in the wardroom tonight for the senior officers is on the right side of the screen - The Right-Handed Gun, starring Paul Newman."
"For the junior officers on the wrong side of the screen - The Left-Handed Gun, starring Namwen Luap."
