The Twilight Zone1985

Sam:
Yeah, well you can just go back to whatever stygian depths you came from, fella. Because I have no intention, thank you, of selling my soul for the solution of any equation.

The Devil:
"Stygian depths," I like that. You mention Dante to most people these days, and they ask you how you liked "Gremlins." You got class. But no can do, babe. You see, we took an option on your soul the moment you summoned me. I'm just a sub-agent here to close the deal. It's all a formality. In other words, you're damned if you do, and damned if you don't.

Sam:
But that's not fair!

The Devil:
Of course it's not fair. We're evil. Look it up.
