Tonight at 9, ESPN presents Ali Rap, which theorizes that Muhammad Ali - through his rhymes and speeches - unknowingly invented rap. And there's a new book called Ali Rap: Muhammad Ali, The First Heavyweight Champion of Rap, which was edited and designed by George Lois and published by Taschen/ESPN Books. To honor Ali and these projects, here are some favorite quotes by the boxing legend over the years:
"I am the greatest!"
"Float like a butterfly, sting like a bee."
"If you even dream of beating me, you'd better wake up and apologize."
"I'm so mean I make medicine sick."
"I'll beat him so bad he'll need a shoehorn to put his hat on."
"Joe Frazier is so ugly that he should donate his face to the U.S. Bureau of Wildlife."
"Wars of nations are fought to change maps. But wars of poverty are fought to map change."
"I'm so fast that last night I turned off the light switch in my hotel room and was in bed before the room was dark."
"It's hard to be humble when you're as great as I am."
"I shook up the world! ... I'm a bad man!"
