Ellerby: [on Sullivan getting married] Marriage is an important part of getting ahead. It lets people know you're not a homo. A married guy seems more stable. People see the ring, they think, "At least somebody can stand the son of a bitch." Ladies see the ring, they know immediately that you must have some cash, and your cock must work.
Colin Sullivan: [laughs nervously] Yeah, it's workin'. Overtime!

Colin Sullivan: Alright, Frank... I need you to get me names, social security numbers and all that...
Frank Costello: Give you? Give you? Who the fuck do you think you are working for?
Colin Sullivan: I'm sorry, I'm sorry...
Frank Costello: I'm just fucking with you. But, you better get organized.

Colin Sullivan: Do you know what will happen if you shoot me?
Billy Costigan: Yeah, this bullet will go right through your fucking head!

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: You're an FBI informant? Are you fucking kidding me?
Frank Costello: Grow up!
[laughing]
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.

[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.

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.
