Gumperson's Law

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: sound.westhost.com/ laws.htm ) and they are more under the category of jokes than phrases of the type this site specializes in.
