In Reply to: Gumperson's Law posted by Helge Skjeveland on December 02, 2008 at 11:12:
: A variation (more formal) of Murphy's Law is Gumperson's, to wit:
: "The probability of something happening is inversely proportional to its desirability."
: Who Gumperson was, I have no idea; but certainly the Law is the expression of a frequently to be lamented reality. Anyone heard of this before? You might want to add it to your archive.
There are a great multitude of variations (for examples see: http://sound.westhost.com/laws.htm%20) and they are more under the category of jokes than phrases of the type this site specializes in.
