Billy Costigan: You're seventy fucking years old. One of these guys is going to pop you. As for running drugs, what the fuck. You don't need the pain in the ass, and they're going to catch you. And you don't need the money.

Frank Costello: I haven't "needed the money" since I took Archie's milk money in the third grade. Tell you the truth, I don't need pussy any more either...but I like it.

Ellerby: Queenan is dead. I'm your boss now.

Dignam: I don't give a fuck, I'd rather hand in my papers first.

Ellerby: World needs plenty of bartenders -- two weeks, with pay!

Frank Costello: I'm concerned about a Chinaman who thinks it's wise to come to a business transaction with automatic weapons.

Frank Costello: For his own good, tell Bruce Lee and the Karate Kids none of us are carrying automatic weapons. Because here - in this country... it don't add inches to your dick. You get a life sentence for it.

Madolyn: [about an odd-looking dessert] I'm waiting for you to make your move.

Colin Sullivan: I don't know, if that thing moves I'm gonna shoot it.

Frank Costello: Fucking rats. It's wearing me thin.

Mr. French: Francis, it's a nation of fucking rats.

Colin Sullivan: Fuck you, fuckin' queers. Firemen gettin' pussy for the first time in the history of fire or pussy. Hey go save a kitten in a tree, you fucking homos.

Other Prisoner: Hey, you Billy Costigan?

Billy Costigan: Yeah. Who wants to know?

Other Prisoner: I know a Sean Costigan, down on L Street.

Billy Costigan: Yeah that's my cousin.

Other Prisoner: Connected. Not too bright.

Billy Costigan: I know.

Other Prisoner: I mean no offense.

Pakistani Proprietor: What's wrong with this fucking country? Everybody hates everybody!

Providence Gangster #1: Come on Babu, I can't do any more. I can't go off, please don't make me go back empty handed. Please don't do this. I wanna help you.

Pakistani Proprietor: Come to my store next Friday. I'll give you the money...

Providence Gangster #1: This is Friday Babu, how many times I gotta tell you?

Pakistani Proprietor: You keep calling me Babu, it's 'Singh' motherfucker!

Providence Gangster #1: I'm trying to help you. Don't you understand?

Pakistani Proprietor: You keep on telling me 'I'm your friend'.

Providence Gangster #1: Yeah.

Pakistani Proprietor: You don't even know my fucking name!

Frank Costello: You want some coke? There it is. Don't move till you're numb.

Colin Sullivan: I think you better call your mother, and tell her you won't be home for supper. Look it, fuck-stick, you don't have to trust me. Just listen to what I am saying to you.

Ellerby: We're not here to solve the case of the missing scumbag, we're here to nail Costello.

Billy Costigan: No, I gotta get out. I can't be doing this anymore. You know what's gonna happen?

Oliver Queenan: What?

Billy Costigan: I know he's gonna find out who I am and he's gonna fucking kill me.

Oliver Queenan: I'm really sorry... I swear to God I am. I'll get you out of this. It won't be immediately but I will get you out. Two weeks at most.

Frank Costello: There is no need to remind you that if you don't find that cheese eating rat bastard in your department... it won't be me who suffers for it.

Colin Sullivan: What I be any good at my job if I didn't fucking already know that?

Frank Costello: Just get him and smoke him the fuck out.

Colin Sullivan: I'll get the rat... you just gotta let me do it my way, Frank.

Oliver Queenan: You're a worker. You rise fast.

Dignam: Like a 12-year-old's dick.

Colin Sullivan: Okay.

Brown: Put down the gun and step away from Sergeant Sullivan!

Billy Costigan: Look, I called you. You specifically. You know who I am. I'm not gonna shoot. I told you to meet me downstairs.

Colin Sullivan: Help me.

Brown: PUT THE WEAPON ON THE DECK AND STEP AWAY FROM SERGEANT SULLIVAN!

Colin Sullivan: Shoot the fuckin' prick already!

Billy Costigan: Where's Dignam? I told you to bring Dignam!

Colin Sullivan: Shoot the motherfucker!

Brown: Put the weapon on the ground and we'll discuss it.

Colin Sullivan: SHOOT THE MOTHERFUCKER!

Billy Costigan: Look, I got boxes of tapes, evidence, all of that! I got proof! He's Costello's rat!

Brown: Maybe you do. But right now I need you to put the weapon on the deck and step away from Sergeant Sullivan!

Frank Costello: Sweetheart, you're giving me a hard-on.

Gwen: Are you sure it's me? Not all that talk about whiffing and crawling up asses?

Frank Costello: Watch your fuckin' mouth!

Gwen: No, you watch it. Let me straighten you out.

Ellerby: Go fuck yourself.

Dignam: I'm tired from fucking your wife.

Ellerby: How is your mother?

Dignam: Good, she's tired from fucking my father.

Ellerby: Yes, those. I don't know what they are, you don't know what they are, who gives a fuck.
