Buzz Aldrin: Famed astronaut, second man on the moon, and puncher of smug faces. Sunday marks the 45th anniversary of the lunar landing — unless, of course, it never happened and the government faked the whole danged thing to make America look super powerful at the height of the Cold War. Is that conspiracy theory likely? Probably not, though there are some who ardently believe in it. Bart Sibrel is one of those lunar truthers. And back in 2002, he ambushed Aldrin outside a Los Angeles hotel and berated him about his supposed role in the hoax, asking him to swear on a Bible he landed on the moon and calling him a "liar" and a "coward." Offended that someone would question his integrity, and fed up with being pestered for so long, Aldrin finally snapped and socked Sibrel in the face.
