- Me, you know, I'm sorry for both of you.

- Well, ain't nothing I can do, is there?

- Except... I'd like to tell you something once, and then I ain't gonna say it again.

- Well, Rocky, you got another shot. It's a second shot at the... I don't know, the biggest title in the world.

- And you're gonna be swapping punches with the most dangerous fighter in the world.

- And just in case, you know, your brain ain't working so good...

- All this happens pretty soon. And you ain't ready. You're nowhere near in shape.

- So, I say, you know, for God's sake, why don't you stand up and fight this guy hard, like you done before?

- That was beautiful!

- But don't lay down in front of him like this! Like a... I don't know, like some kind of mongrel or something. 'Cause he's gonna kick your face in pieces.
