Buzz Aldren being hassled about whether he had gone to the moon.
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.
