You got a nice suit at home or do you like coming to work everyday dressed like you're goin' to invade Poland?Colin Sullivan
One of us had to die. With me, it tends to be the other guy.Frank Costello
[to Frank Costello] You accuse me once, I put up with it. You accuse me twice... I quit. You pressure me to fear for my life and I will put a fucking bullet in your head as if you were anybody else. Okay?Billy Costigan
Colin Sullivan: You're an FBI informant? Are you fucking kidding me?
Frank Costello: Grow up!
Frank Costello: Of course I talked to the FBI.
Colin Sullivan: Do they know who I am?
Frank Costello: I... I never gave up anybody... who wasn't going down anyway. Nobody knows nothin'.
Colin Sullivan: Frank... Frank. Do they know about me?
Frank Costello: I know about you, Colin. You know I'd never give you up. You're like a...
Colin Sullivan: What, like a son? To you? Is that what this is about? All that murderin'... and fuckin'... and no sons?
[They shoot at each other]
Madolyn: Here, this is my card.
Colin Sullivan: Nah, I don't need that. I'm a detective. I'll find you.
[elevator door begins to close; Colin reaches out]
Colin Sullivan: No, I'm just kidding, I need the card.
[after Costigan has quoted Nathaniel Hawthorne] Pfft! What's the matter, smartass, you don't know any fuckin' Shakespeare?Dignam
You have an immaculate record. Some guys don't trust an immaculate record. I do. I have an immaculate record.Ellerby
[to Madolyn] If we're not gonna make it, it's gotta be you that gets out, cause I'm not capable. I'm fucking Irish, I'll deal with something being wrong for the rest of my life.Colin Sullivan
Frank Costello: Good day, father.
Older Priest: Good day, Francis.
Frank Costello: You recall our chat? Little boys. Sucking on their peckers, etc... and so forth. I am as God made me. Is that your rationale? May I remind you - in this archdiocese, God don't run the bingo.
Young Priest: May I remind you - that pride comes before the fall.
Frank Costello: How's Sister Mary Teresa doing? Had a tasty relationship before she took her vows.
[Costello hands the priests a nude drawing of the nun]
Frank Costello: Enjoy your clams, cocksuckers.
[Upon learning the Police have found Delahunt's body and that he was a cop]
Fitzy: I don't believe it.
Mr. French: What can't you believe?
Fitzy: I spent all fucking night dragging the poor bastard in there. Tell me how they find him so fast? Somebody walking a fucking dog ? What fucking size a dog is that? Has to be a big fucking dog, man. I spent all night doing it man.
[pause, Frank stares at him]
Fitzy: I'm embarrassed. I still don't believe he was a cop, I don't believe it.
Frank Costello: The COPS... are saying he's a cop... so I won't look for the cop. Are you soft, Fitz? When I tell you... to dump a body in the marsh, you dump him *IN* the marsh. Not where some guy from John Hancock goes every Thursday, TO GET A FUCKING BLOWJOB!
[Fitzy laughs, Frank hits him]
Frank Costello: Don't laugh! This ain't Reality TV!
Frank Costello: But Colin - I hope I don't have to remind you that if you don't find that cheese-eating rat bastard in your department, most likely it won't be me who suffers for it.
Colin Sullivan: Now why would you have to remind me of that? Would I be any good at what I do if I didn't fucking already know that? Frank, you gotta trust me. Alright, just trust me Frank. Hey, it fucking involves lying and I'm pretty fucking good at that. Right?
Frank Costello: Maybe because it's always been so easy for me to get cunt, that I never understood jacking off in a theater.
Colin Sullivan: Frank? What the fuck is wrong with you?
Frank Costello: [laughing] See anything you like, Colin?
Colin Sullivan: I almost fucking shot you!
Frank Costello: You're not indulging in self-abuse, are you? I hope you're not turning into one of them sob sisters who wants to get caught. You're not cracking up, are you?
Colin Sullivan: I don't crack up.
Frank Costello: Picking a place like this, where any cop can see you. Jesus.
Colin Sullivan: If it was such a fucking bad idea, why'd you show up?
Frank Costello: [turning to face Sullivan] I own the place.
Colin Sullivan: Look, I gotta tell you...
Frank Costello: You're getting re-assigned. I know.
Colin Sullivan: How the fuck do you know that?
Frank Costello: Where'd they put you?
Colin Sullivan: Hey Frank, I gotta find myself.
Frank Costello: You're telling me, sonny boy.
Colin Sullivan: I gotta find the guy you got in the department.
Frank Costello: With everybody looking up their own ass, and you looking for yourself, I'd put my money on nobody finds nothing.
