The Departed quotes

Dignam: Your fuckin' family's dug into the Southie projects like ticks. Three-decker men at best. You, however, grew up on the North Shore, huh? Well, la-di-fuckin'-da. You were kind of a double kid, I bet, right? Huh? One kid with your old man, one kid with your mother. You're upper-middle class during the weeks, then you're droppin' your "R"s and you're hangin' in the big, bad Southie projects with your daddy, the fuckin' donkey on the weekends. I got that right?
Dignam: Yup. You have different accents? You did, didn't you? You little fuckin' snake. You were like different people.
Billy Costigan: You a psychiatrist?
Dignam: Well, if I was I'd ask you why you're a Statie making 30 grand a year. And I think if I was Sigmund fuckin' Freud I wouldn't get an answer. So tell me, what's a lace-curtain motherfucker like you doing in the Staties?
Billy Costigan: Families are always rising or falling in America, am I right?
Oliver Queenan: Who said that?
Billy Costigan: Hawthorne.
Dignam: What's the matter, smartass, you don't know any fuckin' Shakespeare?

Dignam, Billy

My theory on Feds is that they're like mushrooms, feed 'em shit and keep 'em in the dark

Queenan

Our target: microprocessors. Yes, those. I don't know what they are, you don't know what they are, who gives a fuck?
