MUHAMMAD ALI V SONNY LISTON - AP
Heavyweight champion Muhammad Ali stands over fallen challenger Sonny Liston, shouting and gesturing shortly after dropping Liston with a short hard right to the jaw on May 25, 1965, in Lewiston, Maine. The bout lasted only one minute into the first round. Ali is the only man ever to win the world heavyweight boxing championship three times. He also won a gold medal in the light-heavyweight division at the 1960 Summer Olympic Games in Rome as a member of the U.S. Olympic boxing team. In 1964 he dropped the name Cassius Clay and adopted the Muslim name Muhammad Ali. (AP Photo/John Rooney)
