Aziraphale: You could’ve walked away. If you were truly as evil as you like to paint yourself, you would’ve done.
Crowley: Nah. That’s the trouble with you lot. You tend to see things in black and white. Sometimes, you just gotta blur the edges.

Aziraphale: I knew you’d come through for me. You always do.
Crowley: Well, you said, ‘Trust me.’
Aziraphale: And you did.

You might want to think about washing your hands. It’s going to be all the rage in a few years, I’m telling you.

Crowley

Crowley: Gravity. It’s a thing that happens when objects are pulled together. In this case, they’re all pulled downwards because the Earth is the largest thing around.
Gabriel: Why?
Crowley: Uh, honestly, I don’t remember. Seemed like a good idea when we were all talking about it. So things will stay where you put them? Not just drift off?
Gabriel: But it doesn’t stay where I put them. Goes down. Except for flies. They go up.
Crowley: Well observed.

Aziraphale: Look, I am good. You, I’m afraid, are evil. But people get a choice, y’know? They cannot be truly holy unless they also get the opportunity to be wicked. She is wicked.
Crowley: That only works if you start everyone off equal. You can’t start someone off like that and expect her to do as well as someone born in a castle.
Aziraphale: Ah, but no, no, that’s the good bit. The lower you start, the more opportunities you have. So Elbeth here has all the opportunities because she’s so poor.
Crowley: That’s lunacy.
Aziraphale: No, that’s ineffable.

Just trying to keep Wee Moragh and me alive and it doesn’t hurt anyone who isn’t already dead. So you can shove your morals up your arse, Mr. MacFell.

Elsbeth

We humans of Earth have a saying. You can only tell if people are in love by waiting a few days because humans are weird and that’s how it works.

Crowley

Crowley: I don’t know how you lot have managed to stay in charge all this time.
Aziraphale: I’m not sure we have, have we?

Aziraphale: But what am I?
Crowley: You’re just an angel who goes along with Heaven as far as you can.

Michael: But they’re not babies.
Crowley: Certainly not. Was Eve a baby?
Michael: Was she?
Gabriel: No, they can arrive at any size.

Crowley: You mean like a sudden rainstorm forces them together beneath the canopy. They look into each other’s eyes, and realize they were made for each other.
Aziraphale: Sounds a bit unlikely.
Crowley: No, get humans wet and staring into each other's eyes, Va-voom! Sorted.

Shax: You’re in trouble.
Crowley: Obviously. Former demon, hated by Heaven, loathed by Hell. How will our hero cope?
Shax: Are you making fun of me?
Crowley: Would you know if I was?

Good Omens Quotes

What’s the point in creating an infinite universe with trillions of star systems if you’re only gonna let it run for a few thousand years? The engine won’t even be probably warmed up by then.

Crowley

Aziraphale: You made it all yourself?
Crowley: Well, I mean more or less. I wasn’t the original concept designer but I worked very closely with Upstairs on it.
Aziraphale: Well, it’s very pretty.
Crowley: Oh, thank you.
