Aziraphale: You can't leave, Crowley. There isn't anywhere to go.
Crowley: It's a big universe. Even if this all ends up in a puddle of burning goo, we can go off together.
Aziraphale: Go off together? Listen to yourself.
Crowley: How long have we been friends? Six thousand years!
Aziraphale: Friends? We're not friends. We are an angel and a demon. We have nothing whatsoever in common. I don't even like you.
Crowley: You do.
Aziraphale: I'm not consulted on policy decisions, Crawly.
Crowley: Oh, I've changed it.
Aziraphale: Changed what?
Crowley: My name. "Crawl-y" just wasn't really doing it for me. It's a bit too... squirming-at-your-feet-ish.
Aziraphale: Well, you were a snake. So, what is it now? Mephistopheles? Asmodeus?
Aziraphale: God's not actually going to wipe out all the locals. I mean, Noah, up there, his family, and his sons, their wives, they're all going to be fine.
Crowley: But they're drowning everybody else? Not the kids? You can't kill kids.
Crowley: Well, that's more the kind of thing you'd expect my lot to do.
Aziraphale: Yes, but when it's done, the Almighty's going to put up a new thing, called a "rain bow", as a promise not to drown everyone again.
Crowley: How kind.
Aziraphale: You can't judge the Almighty, Crawley. God's plans are...
Crowley: Are you going to say "ineffable"?
