Man On Stoop: I'm sayin', every Friday night in an alley behind the Cut Rate, we rollin' bones, you know? I mean all them boys, we roll til late.
McNulty: Alley crap game, right?
Man On Stoop: Like every time, Snot, he'd fade a few shooters, play it out til the pot's deep. Snatch and run.
McNulty: What, every time?
Man On Stoop: Couldn't help hisself.
McNulty: Let me understand. Every Friday night, you and your boys are shooting craps, right? And every Friday night, your pal Snot Boogie... he'd wait til there's cash on the ground and he'd grab it and run away? You let him do that?
Man On Stoop: We'd catch him and beat his ass but ain't nobody ever go past that.
McNulty: I gotta ask ya: If every time Snotboogie would grab the money and run away, why'd you even let him in the game?
Man On Stoop: What?
McNulty: If Snotboogie always stole the money, why'd you let him play?
Man On Stoop: Got to. This America, man.

Still working in the basement for regular wage, thinking of some shit to make the fries taste better or some shit like that. Believe.

Marla Daniels: You cannot lose if you do not play.
