Gregory: You comin' out to the bar, tonight, man?
Shmegory: Can't. Rosa's having me work this Saturday.
G: You take too much from that cunt. I mean it.
S: Don't call her that.
G: Why not? If she's not a cunt, I don't know who is.
S: No, I mean, she's worse than a cunt, she's a, uh...she's a...cunt-cunt.
