Daniels: So, one thieving politician trumps twenty-two bodies? Good to know.

Freamon: When they took us off Marlo this last time, when they said they couldn't pay for further investigation... I regarded that decision as illegitimate.
Sydnor: Illegitimate?
Freamon: And so... I'm responding in kind. I'm going to press a case against Marlo Stanfield without regard to the usual rules. I'm running an illegal wiretap on Marlo Stanfield's cellphone.
Sydnor: Fuck. Lester?
Freamon: If you have a problem with this, I understand completely, and I urge you to get as far fucking away from me as you can.

Gus: Just because they're in the street doesn't mean they lack opinions.
Templeton: Where am I going to find homeless people?
Gus: Not at home, I imagine.

Gus: You ever notice that the guys who do that, the Blairs, the Glasses, the Kelleys, they all start with something small, you know. Just a little quote that they clean up. And then it's a whole anecdote. And pretty soon, they're seeing some amazing shit. They're the lucky ones who just happen to be standing on the right street corner in Tel Aviv when the pizza joint blows up and the human head rolls down the street with the eyes still blinking!
Klebanow: The pictures were sent to him. The police have confirmed...
Gus: It always starts with something true, something confirmed.

Landsman: [At McNulty's "wake"] He was natural po-lice. Yes, he was. And I don't say that about many people. Even when they're out here on the felt. I don't give that one up unless it happens to be true. Natural po-lice. ... [pretends to choke up] ... But, Christ, what an asshole!
...
Landsman: Jimmy, I say this seriously. If I was laying there dead on some Baltimore street corner, I'd want you standing over me, catching the case. Because, brother, when you were good, you were the best we had.
Bunk: Shit, if you were lying there dead on some corner, it probably was Jimmy that done ya.

Landsman: [To McNulty] From everything we've given you, fire should be shootin' outta your ass. But there you sit, like a genital wart.

Marlo: [after finding out Omar jumped from a 5th floor balcony] Don't seem possible.
Chris: It don't.
Marlo: That's some Spiderman shit there. We missed our shot. Now he goin' be at us.

Marlo: Man, I don't talk on no cell phones.
Spiros: Here. To call for lunch, you can talk. To call your girl, you can talk. To call your lawyer even, you can talk--the law says that is between you and the lawyer. Alright? To find out what movie is playing down the street, you can talk. All of that is good because all of that tells them... there is nothing good to hear.

McNulty: Wonder what it feels like to work in a real fuckin' police department.

McNulty: You lying motherfucker, you're as full of shit as I am. And you've got to live with it and play it out as far as it goes, right? Trapped in the same lie. Only difference is, I know why I did it. But fuck if I can figure out what it gets you in the end. But, hey, I'm not part of your tribe.
Templeton: You're not serious?
McNulty: No, no, I'm a fucking joke. And so are you.

McNulty: You miss what you had though?
Kima: I still got too much dog in me to be settled like that.

McNulty: You start to tell the story, you think you're the hero, and then when you get done talking...

Michael: Everything so serious now.

Michael: Why? What I do wrong?
Snoop: Chris locked up behind somethin' he done for you. And you downtown wit' the police.
Michael: I ain't say a word.
Snoop: Yeah, that's what you say. But it's how you carry yourself. Always apart. Always aksin', "Why?". When you should be doin' what you're told. You was never one of us. And you never could be [...] How my hair look, Mike?
Michael: You look good girl. [gunshot]

Norman: Daniels isn't ready. He's only been colonel for a year.
Carcetti: A year will do in a pinch. You float it with one of your bunkies on Calvert Street. See how it plays.
Norman: Burrell reads that, he'll shit melons.
Carcetti: I fucking hope so. It's Baltimore. No one lives forever.
