Man Without a Star (1955)
Dempsey Rae: You'll learn. Or you'll be up to your armpits in beef.
[Dempsey has just given Jeff Jimson a quick-draw and gun-twirling lesson]
Jeff Jimson: Aw, Demps, when do I learn THAT?!
Dempsey Rae: You don't. That's all a lotta hogwash, kid. Look, know this: twirlin' a gun never saved a man's life. There's only one thing you gotta learn. (Pulls his gun and fires) Get it out fast! And then...put it...away...slow. Get what I mean, kid?
Dempsey Rae: A maverick...a calf with no mother. No brand neither.
Jeff Jimson: Why not?
Dempsey Rae: Oh, on account he was missing at roundup time. He outgrew his mother and wandered off. Sort of like you.
