The Three Laws of Robotics:
1. A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
-I, Robot (Asimov)
but found this Dumbledore spoof video on gprime.net to be incredibly funny XD
