"I done wrestled with an alligator, I done tussled with a whale, only last week I murdered a rock, injured a stone, hospitalized a brick. I'm so mean I make medicine sick.
There's not a man alive who can whup me. I'm too fast. I'm too smart. I'm too pretty. I should be a postage stamp. That's the only way I'll ever get licked.
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.
I am the astronaut of boxing. Joe Louis and Dempsey were just jet pilots. I'm in a world of my own.
If you dream of beating me, you'd better wake up and apologise.
There are two things that are hard to hit and see. That's a spooky ghost and Muhammad Ali.
I'm not the greatest; I'm the double greatest. Not only do I knock 'em out, I pick the round.
Boxing is a lot of white men watching two black men beat each other up.
People don't realize what they had till it's gone. Like President Kennedy - nobody like him. Like The Beatles, there will never be anything like them. Like my man, Elvis Presley - I was the Elvis of boxing."

Muhammad Ali
