McKay: I didn't give you my word - I gave you my promise.
Flagg: It's the same thing!
McKay: No it ain't - one's my promise, and the other's my word!

Mayor Wilker: [talking about the plan to stop the train] Why don't you take McKay here with you?
Flagg: He's one of 'em!
Mary: No he isn't... not any more... are you, Mr. McKay?

McKay: There's only one plan and it's as plain as the nose on your face. You can't stop the train from comin' to town 'cause they got the telegraph covered. What you gotta do is stop the train from *stoppin* in town.

McKay: Waco!
[holds his right hand over his gun, challenging Waco]
Waco: You got style, McKay; I'll give you that much.
McKay: [Waco shoots first and wounds McKay. McKay pivots, fires, and kills Waco] I thought I could beat 'im.
Flagg: You beat him.

McKay: You got a privy out back?
Flagg: The name of this town is Progress - there's one inside.
McKay: *In*side?
Flagg: Yeah, just under the staircase.
McKay: [McKay jiggles the handcuffs; Flagg unlocks them and follows as McKay walks to the staircase] You gonna hold my hand?
McKay: [McKay walks into the bathroom and looks around. He pulls the chain on the toilet, which flushes] I'll be damned.
