The Departed quotes

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

Oliver Queenan: All cell phone signals are under surveillance, due to the courtesy of our Federal friends over there.
Ellerby: Patriot Act, Patriot Act! I love it, I love it, I love it!

Queenan, Billy

Fitzy: She didn't notice us, she must be a cop.
Delahunt: Yeah, she's probably the fucking Police Commissioner.

Fitzy, Queenan
