McNulty: You see the preliminary? Positives for oral, vaginal, anal. No IDs, no passports, no visas, no real money - and the girls are coming across the water like that.
Bunk: Yeah.
Lester: McNulty has a theory...
Bunk: Does he now?
Lester: You deductive motherfucker, you.
Bunk: So he's gonna wander in here with some johnny-come-lately bullshit about how all these girls must be coming over here as prostitutes. Talking about how if they ain't got the cash to travel better than a container ship, then they sure as shit don't got the money to pay a plastic surgeon.
Lester: Then he's gonna go past that. And say something about that one found dead in the water - being tossed off the ship after she's already dead from a beat-down?
Bunk: But why did she get beat? He's gonna ask us that like we don't know.
Lester: Then he's gonna answer his own question, and say her swabs are negative, right? Fuck or fight with all them sailor boys - and she fought.
Bunk: So, it got a little rough, she got banged around, she comes up dead. And then, somebody panics and tosses her in the harbour overnight before the ship ties up.
Beadie: But the other girls saw.
Bunk: So now the other girls, they get told to get back in that can. And our man, to cover this shit up, he gets up on top and bangs down the airpipe. [stands up, sighs dramatically] Anything else you wanna tell us?

Nick: Seniority sucks.
La La: If you ain't a senior.

Omar: Look, Dante, what's it gonna take for you to be convinced, man? I don't bed no babies. [pauses] Huh?
Dante: What you think?
[Omar and Dante start making out]
Dante: You gonna have to do better than that.
Omar: Oh, indeed.

Omar: That wasn't no attempted murder.
Levy: Then what was it, Mr. Little?
Omar: I shot the boy Mike-Mike in his hind parts, that all. [jury members laugh] Fixed it up so he couldn't sit right. [Judge Phelan chuckles]
Levy: Why'd you shoot Mike-Mike in his, um... hind parts, Mr. Little?
Omar: Let's say we had a disagreement.
Levy: A disagreement over?
Omar: Well, you see, Mike-Mike thought he should keep that cocaine he was slingin' and the money he was makin' from slingin' it. I thought otherwise.

Prez: What if they're not sneaking anything off this time? What then?
Lester: Ah then, tragically, you will have wasted yet another day in a life you've already misspent in the service of the City of Baltimore.

Prison Warden: Hell, if you can't win the war on drugs in a prison, where the hell you gonna win it?

Proposition Joe: [about Brother Mouzone] You don't think I'm gonna send any of my people up against Brother? Shit, That nigga got more bodies on him than a Chinese cemetery.

Rawls: Do you even know what this detail's about Lieutenant?
Daniels: Some kinda beef that Valchek has.
Rawls: Two fuckin' Polacks pissin' on each other's leg.

Rawls: Sergeant! Your floater's come back. County boards are puttin' her on our side of the bridge.
Landsman: No fuckin' way.
Rawls: Yeah, some useless fuck in our marine unit faxed 'em a report on the early morning tides and wind currents. Shows the body went into the water west of the bridge and drifted out.
Landsman: McNulty.
Rawls: [laughs] Fuckin' Jimmy. Fuckin' with us for the fun of it. I gotta give the son of a bitch some credit for wit on this one. [laughs] Cocksucker.
Landsman: Motherfucker.

Rhonda: [reading an affadavit] You all cannot spell for shit.
Bunk: Well, would we be police if we could?

Sergei: Family cannot be helped.
Proposition Joe: Who you tellin'? I got motherfuckin' nephews and in-laws fucking all my shit up all the time and it ain't like I can pop a cap in their ass and not hear about it Thanksgivin' time. For real, I'm livin' life with some burdensome niggers.
...
Nick: Thanks for bein' straight on this.
Proposition Joe: Fool, if it wasn't for Sergei here, you and your cuz' both would be cadaverous motherfuckers.

Shamrock: We done gone so far from Baltimore, we're losing the station. Yo', try a Philly station or some shit like that.
Bodie: The radio in Philly is different?
Shamrock: Nigga, please. You gotta be fucking with me, right? You ain't never heard a station outside of Baltimore?
Bodie: Yo' man, I ain't never left Baltimore except that Boys Village shit one day, and I wasn't tryin' to hear no radio up in that bitch.

Sobotka: What do you say, Johnny? What do you say to any question?
Johnny Fifty: I take the Fifth Commandment.

Sobotka: You know what the trouble is, Brucey? We used to make shit in this country, build shit. Now we just put our hand in the next guy's pocket.

Spiros: [about Nick Sobotka] You don't have to worry about Nicko...
The Greek: You are fond of him Spiros. You should have had a son.
Spiros: But then I would have had a wife.
