No One Believed These Johnny Weissmuller Stories! Until They Watched This! Johnny Weissmuller wasn’t born in America. He used his BROTHER’S birth certificate to compete in the Olympics. Technically, he was never a U.S. citizen. But what if the lies were nothing compared to the documented truth? Five Olympic gold medals. 67 world records. Never lost a single freestyle race for almost TEN YEARS. Pulled 11 drowning people from Lake Michigan. And a Tarzan yell that saved him from Cuban rebels with guns drawn.
