The Oklahoma Kid (1939)
Humphrey Bogart: Whip McCord
John Kincaid : What's your proposition?
Whip McCord : You go right ahead and build your town and attract settlers.
John Kincaid : So you can take away their money at faro and roulette, eh?
Whip McCord : Yeah, that's the idea. You take care of their virtues, I'll take care of their vices. Simple, ain't it?
