Murphy's Far Falling Unreachable Theory
The theory that when we accidentally drop an object (where ever we happen to be at the moment) it no doubt falls or rolls to the farthest, unreachable place. It is a mysterious theory that never fails to happen.
I was putting on my make up and my lipstick fell on the floor. Murphy's Far Falling Unreachable Theory kicked in because it was no where to be found. I had to hunt and excavate the room in order to finally find it behind the dresser under the rug.
