My kind of murphy's law -

 When you feel strangers pain in a work bathroom when the automatic sinks and towel dispensers seem to be mocking you. And you joke about how you need to be a sink ninja to keep the water running to wash your hands and help them get their sinks started, and then show them how to "kick start" the towels with a pseudo round house, it will be an important partner of the company's entourage and you come face to face with the laughing important partner who is watching your silly antics as you head out the door.  Sigh.... Always so graceful and eloquent, that is me.
