Billy Costigan: Cranberry juice.
Man Glassed in Bar: It's a natural diuretic. My girlfriend drinks it when she's got her period. What, do you got your period?
Billy Costigan: Get your fuckin' hands off me!
Mr. French: Hey, hey, hey... do you know me?
Billy Costigan: No, no.
Mr. French: Well, I'm the guy that tells you there are guys you can hit and there's guys you can't. Now, that's not quite a guy you can't hit, but it's almost a guy you can't hit. So I'm gonna make a fuckin' ruling on this right now. You don't fuckin' hit him. You understand?
Billy Costigan: Yeah, excellent. Fine, fine, fine.
Mr. French: I fucking know you. I know your family. You make one more drug deal with that idiot fucking cop-magnet of a cousin of yours and I'll forget your grandmother was so nice to me. I'll cut your fucking nuts off. You understand that?
Billy Costigan: Yeah, yeah, I do.
Mr. French: What are you drinkin'?
Billy Costigan: A cranberry juice.
Mr. French: What is it, your period? Get him a... cranberry juice. Hey, fuckhead, that's Jackie's nephew.
Man Glassed in Bar: Oh.
Mr. French: What? "Oh" fuckin' what?
Get the fuck outta here.
Billy gets into a fight in the bar with a guy who made fun of him for ordering a cranberry juice. As a result, he meets French.
