The Treasure of the Sierra Madre1948

Bob Curtin:
OK, I'm a liar. There isn't a Gila monster under there. Let's see you stick your hand in and get your goods out...Reach in and get your goods. If you don't we'll think you're yella, won't we, Howard? They never let go, do they Howard, once they grab onto you? You cut 'em in two and the head'll still hang on until sundown, I hear. By that time, the victim doesn't usually care 'cause he's dead anyway. Isn't that right, Howard?...What's the matter, Dobbsie? Why don't you stick your hand right in and get your treasure? It couldn't be because you're scared to, could it, after the way you've been shooting your mouth off. Show us you ain't yella, Dobbsie. I'd hate to think that my partner had a yellow streak up his back.
