Muhammad Ali was a masterful boxer, winning the heavyweight championship three times while redefining the sport. Outside the ring, Ali often used his mouth to fight his battles. Whether he was taunting opponents like Joe Frazier or George Foreman, or backing up his religious, political and social stances, Ali was an effective orator. Here are some of his greatest moments.
