- Excuse me, Jack.

- Yeah?

- I was thinking about what the Colonel was saying, you know, about my name.

- Uh-huh. I was just wondering if you had any ideas.

- I had some thoughts on it, yeah. What about you? What do you think?

- Well, my idea was, you know, I just want a name I want it so it can cut glass, you know, like razor-sharp.

- Razor-sharp. Right.

- Yeah, well, when I close my eyes, I see this thing. It's like this big sign. And the name is in, like, bright-blue neon lights with, like, purple outline.

- And this name is just so bright and so sharp that the sign, it just blows up because the name is just so powerful.

- It says, Dirk Diggler.

- I think heaven has sent you here, Dirk Diggler. I think the angels have blessed us all because of you.

- You're Dirk.

- Dirk Diggler. Ha ha!
