- It's a Derringer, smithy. Small but effective. The last time I used it, fellow took two whole days to die. Bled to death inside. It was real, real painful.

- That means you'll be dead by about supper time Monday.

- Excuse me. I don't know who you think you are, but we're dancing.

- Well, look at what we have here. Ain't you gonna introduce me to the lady? I'd like a dance.

- I wouldn't give you the pleasure. You'll just have to go ahead and shoot.

- All right.

- No, no. Emmett, I'll dance with him.

- Boys, keep the blacksmith company while I get acquainted with the filly!

- I don't dance very well when my partner has a gun in his hand.

- You'll learn. You'll learn.

- You know, smithy, maybe I'll just take my $80 worth out of her!

- Tannen, leave her alone!

- Yeah, I bet there's something you can do that's worth $80.
