Peaceful robot / human talks looked to be on the verge of a meltdown in Iowa on Monday. Former president Bill Clinton was treated to barrage of output from a robot seeking for an apology regarding a 1992 comment Bill made concerning rapper Sister Souljah. The robot -- or potentially a human impostor dressed to look like one -- then threw color cards in the air, and was escorted away, but not without a parting shot from Clinton about picking a more environmentally-friendly way to protest. Rumors of the robot shouting "please tase me, humans" as a parting shot are unconfirmed. The video can be found at the read link.
