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 any orders given to 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.
LOL! Robots killing people and not doing what they're supposed to! Let's joke about it -- it's funny! You're all as good as dead.

Thanks to Nate, Jonny S, bryson, jantunes and Nicky, who know there's no such thing as safe robots. Or sex (but Ziploc brand freezer bags do help reduce the risk).
