From Wikipedia:

The word “Deployment” isn’t any where in here!?  But it did originate at a MILITARY BASE! I knew it!! : )

Murphy’s law is a popular adage in Western culture that most likely originated at Edwards Air Force Base in 1948. The Law broadly states that things will go wrong in any given situation, if you give them a chance. “If there’s more than one way to do a job, and one of those ways will result in disaster, then somebody will do it that way.” It is most often cited as “Whatever can go wrong, will go wrong” (or, alternately, “Whatever can go wrong will go wrong, and at the worst possible time,” or, “Anything that can go wrong, will”).
