About this quote

Exclaimed by Muhammad Ali — then still known as Cassius Clay — in the immediate aftermath of his first-round stoppage victory over world heavyweight champion Sonny Liston at the Miami Beach Convention Hall on February 25, 1964. Ali was a 7-to-1 underdog; Liston refused to answer the bell for the seventh round, making the 22-year-old Clay the youngest heavyweight champion in history. The next morning, he announced he had joined the Nation of Islam and would take the name Muhammad Ali.
