The Departed quotes

Oliver Queenan: Do you know what we do here? My section?
Billy Costigan: Sir, yes, sir. I have an idea...
Dignam: Whoa, whoa, whoa. Let's say you have no idea and leave it at that, okay? No idea. Zip. None. If you had an idea of what we do, we would not be good at what we do, now would we? We would be cunts. Are you calling us cunts?
Oliver Queenan: Staff Sergeant Dignam has a style of his own. I'm afraid we all have to get used to it.

Dignam, Billy

Oliver Queenan: One of you mugs got a light.

Fitzy, Queenan

Ellerby: Staff Sergeant Dignam is our liaison to the the undercover department, his undercover work is extensive. He's here to give us his report. Sergeant Dignam.
Dignam: Ok. My people are out there. They're like fuckin' indians. You're not gonna see 'em you're not gonna hear about 'em except from me or Captain Queenan. You will not ever know the identity of undercover people. Unfortunately, this shithole has more fuckin' leaks than the Iraqi Navy.
Ellerby: Fuck yourself.
Dignam: I'm tired from fuckin' your wife.
Ellerby: How's your mother?
Dignam: Good, she's tired from fuckin' my father.

Dignam, Billy
