Although not yet classic lines, but will get there; Dragon Age 2:
■Isabela: "My dear, you wouldn't consider...leaving Alistair with me, would you? Perhaps let me borrow him for a week every summer? I'm sure we could work out a deal."
■Warden: "Would you lend me your ship?"
■Isabela: "Of course not! You would misuse the ship-- Which, I suppose, is exactly what I would do with Alistair, though I suspect he would enjoy it while the ship wouldn't."
■Alistair: "Not that the idea of being borrowed isn't terribly fascinating, but let's not forget the darkspawn. There may not be a week every summer, or any summer."
■Isabela: "Darkspawn! Is this the only thing men think about these days? What about the good old obsessions? Breasts, firm buttocks, wet frocks?"
■Alistair: "Hmm... wet frocks..."
and
■Isabela: How's marriage been treating you, big girl?
■Aveline: It's been good. No, great. I'd forgotten what it was like to...
■Isabela: Be flipped ass over tits and hammered like a bent nail?
■Aveline: To. Be. Loved.
■Isabela: Oh. Right, of course.
■Aveline: Not that I'm complaining about the other thing.
Keep em' coming...
