Butch and Sundance are trapped and cornered by the posse on a ledge at the edge of a steep rock canyon with nowhere else to go. Their frequent comic, self-deprecating bantering is a highlight of the film, especially illustrated when they overlook raging rapids fifty feet below and are faced with a choice between a hopeless shoot-out and a near-suicidal leap:
Butch: DAMMIT! Well, the way I figure it, we can either fight or give. If we give, we go to jail.
Sundance: I been there already.
Butch: But if we fight, they can stay right where they are and starve us out or go for position - shoot us; might even get a rockslide started and get us that way. What else could they do?
Sundance: They could surrender to us, but I wouldn't count on that. (He watches the posse maneuver.) They're goin' for position, all right. Better get ready. (He loads his gun.)
Butch: Kid - the next time I say, 'Let's go someplace like Bolivia,' let's go someplace like Bolivia.
Sundance: Next time. Ready?
Butch: (looking into the deep canyon and the river far below) No, we'll jump.
Sundance (after looking down): Like hell we will.
Butch: No, it'll be OK - if the water's deep enough, we don't get squished to death. They'll never follow us.
Sundance: How do you know?
Butch: Would you make a jump like that you didn't have to?
Sundance: I have to and I'm not gonna.
Butch: Well, we got to, otherwise we're dead. They're just gonna have to go back down the same way they come. Come on.
Sundance: Just one clear shot, that's all I want.
Butch: Come on.
Sundance: Uh-uh.
Butch: We got to.
Sundance: Nope! Get away from me!
Butch: Why?
Sundance: I wanna fight 'em!
Butch: They'll kill us!
Sundance: Maybe.
Butch: You wanna die?!
Sundance: (waving his pistol at the river far below) Do you?!
Butch: All right. I'll jump first.
Sundance: Nope.
Butch: Then you jump first.
Sundance: No, I said!
Butch: What's the matter with you?!
Sundance: (wildly embarrassed) I can't swim!
Butch: (guffawing at his partner) Why, you crazy - the fall'll probably kill ya!
LOL
Here's another: "You just keep thinkin' Butch. That's what you're good at."
