— -- One of the greatest fighters in the history of boxing, three-time heavyweight champ Muhammad Ali charmed millions with his wit and confidence in the ring and inspired many more with his commitment to humanitarian causes. Here's a look at some of his most memorable quotes.
'Float Like a Butterfly, Sting Like a Bee'
The brash, underdog Muhammad Ali promised boxing fans he'd "float like a butterfly, sting like a bee" against Sonny Liston. At age 22, he stunned the larger Liston, beating the champ in seven rounds in Miami to win his first heavyweight title. In their next match in 1965, Ali floored Liston with a hard, quick blow minutes into the bout and retained his crown when the referee stopped the fight.
