The Quick and the Dead

Eugene Dred: — It's lights out, Kid! I'm gonna be pissing on your grave tonight. You're through.
Horace: — Quiet! Quiet! Gentlemen, please remember... you must not draw... until that clock makes the first chime of the hour. Once that happens, you may fire at your convenience.
Fee "The Kid" Herod: — Whoa, now. What if somebody gets too excited and starts shooting early?
John Herod: — Yeah. If he cheats, he'll be eliminated from the contest.
Horace: — Whoever is standing after the draw... is the winner. If both men are still standing, you must continue firing. Do I make myself clear? Gentlemen, the street is yours.
