(GUNSHOTS, PEOPLE SCREAMING IN THE CASINO)

- Is this the Daily News? Well, I'm a citizen here in Denver, Colorado. I just saw something that I'm sure you want to know about.

- Cassius Clay is in town. Yes, Cassius Clay! He's in town. I just saw a big red bus with the name Cassius Clay painted on the bus and the sign said, The world's most colorful fighter.

- Yes. I'm serious. This is no crank call, it's no joke. Cassius Clay is in town. As a matter of fact, I'm looking out the window now. He's outside Sonny Liston's house with a bunch of men on the bus.

- Yes, they were all colored. Well, I don't like to say this, but they are all niggers.

- Yes. It's going to be... Trouble? I don't really know. He's not here to play checkers.

- So, I'm calling you now. Call the police, or get the newspapers, because you have a scoop.

- I've come to haunt you. I've come to haunt you.

- Sonny Liston, where do you live, you big, ugly bear?

- You big, ugly bear. I know you're out here somewhere.
