The Undiscovered Law Of Robotics

Isaac Asimov, of course, invented the famous Laws of Robotics. But there is one he forgot to write down (or perhaps he concealed it, fearing the knowledge might destroy us).

You see, there's Hugo:

Yes, the Fourth Law Of Robotics: Even A Robot Can Cry!

Or perhaps the Fourth Law is "Women Befuddle Robots."
