Finagle’s Law (also known as Melody’s law, Sod’s Law, or Finagle’s corollary to Murphy’s law) is an extension of Murphy’s Law but with an added element of terrible timing. It suggests that not only do things will go wrong, but they tend to do so at the most inconvenient or least unexpected moment possible.
