[...]

- Al Carrara's here. He's got a message from Sonny Liston.

- Oh, yeah. Hey, how you doin'?

- How you doin'?

- I've been authorized to give you this message if you've won the fight.

- The champ wants you to drink your orange juice and drink your milkshake. You talked yourself into a title bout.

- He just hopes you can keep your mouth shut, or he'll ram his fist so far down your throat, it'll take him a week to pull it out.

- I'll tell you what to do, message boy. You go back and tell him that I appreciate the opportunity of fighting for my title, 'cause it's going to be mine.

- Also, you tell him that after the fight, don't worry, because he will not be unemployed, he can be my chief sparring partner. You go tell him that, dear.

- I'll see you.

- That's right.

- Tell him that, message boy. Be sure he gets that.

- Boy, you can ride a bicycle. How you doing?

- Fine, how are you?

- All right.
