Muhammad Ali
“I got nothing against no Viet Cong,” Muhammad Ali said about the possibility of him fighting in the Vietnam War in the 1960s. “The Greatest” was then stripped of his boxing license and couldn’t box for over three years. Once reinstated, Ali eventually capped things off by KO’ing George Foreman in the historic, thrilling “Rumble In The Jungle” in 1974 to regain his world championship belt.
