Supernatural, Season 3

Casey:
Hey, I didn't pull any triggers.

Dean:
Yeah? You did something.

Casey:
You want to know what I did -- what I really did? I had lunch.

Dean:
Lunch?

Casey:
Me and Trotter. He had a cheeseburger, I had a salad, and I just pointed out the money that could be made with a few businesses that cater to harmless vice. So Trotter built it, and, man, did they come. Supposedly god-fearing folk, waist-deep in booze, sex, gambling. I barely lifted a finger.

Dean:
That's it?

Casey:
You don't get it. All you got to do is nudge humans in the right direction. Some whiskey here, a hooker there, and they'll walk right into hell with big,fat smiles on their faces. Your kind is corrupt, Dean. Weak. Our will's stronger. That's why we'll win.

Dean:
And that's how it ends?

Casey:
No. That's how it begins.
