The Departed is one of my favourite movies and Captain Ellerby's words about marriage below are really great.
God bless wedding ring ;)
Ellerby: How is your wedding coming along?
Colin Sullivan: Great, great; she's a doctor.
Ellerby: That's outstanding.
Colin Sullivan: Yeah.
Ellerby: Marriage is an important part of getting ahead: lets people know you're not a homo; 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 you must have some cash or your cock must work.
Colin Sullivan: [laughing] Yeah, it's working... Overtime!
Ellerby: I'm glad to hear that.
Colin Sullivan: Yeah... Thank you.
