jan 8, 1966 - On February 25, Clay goes up against favored Sonny Liston. In what will become his trademark, Clay begins taunting Liston, calling him an "ugly old bear," promising to "float like a butterfly, sting like a bee." Clay is credited with a knockout and becomes the heavyweight champion of the world after Liston fails to come out of his corner for the seventh round. Clay coins the phrase "I am the greatest!" -- a phrase for which he will forever be known.
