- Sundance: [about Aaron] He may not hold the world record for stubbornness, but he sure sets a mark for most other men to shoot at.
- [upon hearing Bearcat's loud, off-key singing]
- Aaron Donager: There's no doubt about it - drunk or sober, in the whole of Colorado, there ain't another voice as terrifyin' as that... Beartracks Conlon.
- Sundance: That is the only voice I ever heard that was aged in wood.
- Beartracks Conlon: I'll admit I ain't much of a singer, but it sure do scare off the bear and the mountain cats.
- Aaron Donager: Wouldn't surprise me none if it didn't cure warts as well.
- [Beartracks has broken his leg]
- Aaron Donager: How'd you do that, Beartracks?
- Beartracks Conlon: Well, I figured you'd ask me that; now, I guess I'm gonna have to tell you. You just think of the most mortifyin' thing could happen to an old trapper like me and that's just exactly what happened. I did it, I stepped my foot right smack in the middle of one of my own traps... and if I wasn't such a kindhearted old cuss, I'da just left myself there to die - that's just how disgusted I was.
- Oliver Weatherford: You see, the fountainhead of all business principle and practice is the law of supply and demand. They operate inexorably. Now when the supply is greater than the demand, well, the influence on the bargaining power is effected proportionally.
- Sundance: You know, you can forget about all that money we lost; forget about all that time we invested; all that aggravation we went through - just think about poor old Beartracks...
- Aaron Donager: Sundance...
- Sundance: ...a whole season's worth of work - that's all he's got to show for it.
- Aaron Donager: Sundance, it's been two whole hours since Weatherford pushed off...
- Sundance: [disgusted] Apple pie.
- Aaron Donager: ...don't you think if we put our heads together, we could maybe come up with a different topic of conversation?
- [during the Indian attack, Weatherford hides behind a large rock]
- Sundance: All right, you can come out now.
- Oliver Weatherford: But they'll be back, won't they?
- Sundance: Likely, yeah.
- Oliver Weatherford: We're outnumbered. We don't have a chance!
- Sundance: You could be right, Mr. Weatherford. I reckon this is one time your law of supply and demand isn't operatin' in your favor.
- Sundance: I don't know about you, but I'm gonna have me a cup of coffee.
- Oliver Weatherford: You-you mean you're just gonna sit there and wait for them?
- Sundance: Well, I suppose we could go lookin' for 'em, but that seems a little more obligin' than the situation calls for.
- Oliver Weatherford: Tell you what I'll do, though. I'll let you have the wagon and everything in it for the horse.
- Sundance: That ain't much of a bargain. You was goin' to leave the wagon here anyway.
- Oliver Weatherford: Well, I'll buy the horse from you!
- Sundance: Oh, wait a minute. I-I don't see how I could do that. I mean, my horse is like blood kin to me. I expect Mr. Donagan over there feels pretty much the same about his.
- Oliver Weatherford: Well, then I'll buy the mule from you. He's not a distant cousin.
- Sundance: No, but he's a good friend. He's loyal, trustworthy - never talks back.
- Oliver Weatherford: You're taking advantage of me just because you can.
- Sundance: No, I just learned my business methods from you, that's all. Now you told me - you said, "Price is affected by the law of supply and demand." Now, I got the supply and you got the demand. You'll pay five hundred dollars for this mule or you'll have to walk.
- Oliver Weatherford: I'll get the money.
- Sundance: If a snowstorm catches us before we reach the flats, they'll likely to be chippin' us out of the hillside come spring thaw.
- Chief Whitefeather: This wagon... not yours?
- Sundance: Sure it is. I make a deal for it - me and my partner
- Chief Whitefeather: Whitefeather make deal for horses. Find Blackfeet with them; kill Blackfeet; take horses. Deal?
- Aaron Donager: That's what I call the law of supply and demand in its purest form.
- Chief Whitefeather: You are more than friend. You are my brother!
- Sundance: [to Aaron] I'm just glad I ain't got no more brothers like him. I couldn't hardly afford 'em.
- [last lines]
- Aaron Donager: Some trip. We crawl over the dang mountain and just about get our forty dollars back.
- Sundance: Well, we got a little more than that, Aaron.
- Aaron Donager: Like what for instance?
- Sundance: Like a little learnin' in the law of supply and demand that I ain't gonna forget in a hurry for instance.
