- Well, hey, hey, I'm not saying you're not ready or anything, but personally, if it were me, I wouldn't mind postponing a couple of weeks.

- Postpone?

- Yeah. I mean, come on, Apollo, we don't know anything about this guy you're fighting, really.

- Look, okay, okay, let's say I postpone, right? I pull out, somebody else steps in and whips this chump, then where does that leave me?

- What do you mean leave you, Apollo?

- It's just some kind of exhibition fight. This thing don't mean nothing.

- No, no, no, man. That's where you're wrong. This is not just an exhibition fight that doesn't mean anything.

- Look, this is us against them. What are you talking about? Come on.

- Maybe you don't know what I'm talking about now, but you will when it's over. Believe me, you will when it's over.

- Good luck. I hope after we can be friends.
