Murphy's Laws for Genealogists

According to Reader's Digest for December 2001 on page 132, the origin of Murphy's Laws comes from the late 1940's and an Air Force officer, Capt. Ed Murphy who was a very picky aircraft engineer by training.  He complained of an incompetent technician on his team by saying, "If there is any way to do it wrong, he will."  His associates began calling his pessimism "Murphy's Law", and mentioned it in a press conference.  The idea caught on and is with us to this day.
If you know of other "Murphy's Laws" for Genealogists (or can create some from your own experiences), e-mail me and I will add them.

            "The person who used the film you need is the only one who ever comes in and leaves the film on the reel backwards because they don't know how to rewind."
