Pete Siekovich: You don't get much rain on a road to Hell. You hear all kinds of stories... like in China and India. They got trains there; in Russia, they got tram lines. And in Mexico, it's old buses on dusty roads. Always at night.

(driving through Hell)
Pete Siekovich: By the time we get to the next truck stop, the rain'll be stopped, anyway.
Johnny Davis: Truck stop? Here?
Pete Siekovich: Wherever you got truck drivers, Johnny, you got truck stops.

Manager: Sounds to me you've been taken in by a lot of secular intellectual propaganda. I've been only in charge here for a short while. My predecessor wasn't a religious man. He thought this was a job just like any other where you could compromise every now and then. But you can't. Not when your keeping the land clean. As it says in Psalms: "The ungodly are like the chaff which the wind driveth away. Therefore the ungodly shall not stand in the judgment, nor sinners in the congregation of the righteous." Sinners, John... the murderers, the muggers, the hustlers, the pornographers, atheists, heathens, and so-called humanists.
Johnny Davis: You mean... anyone who doesn't measure up to your standards.
Manager: Not my standards, John. The only standards that matter. Age-old inviolate standards that God-fearing people have observed for centuries.

Elderly Woman: Why are you doing this?
Johnny Davis: I'm just doing my bit, lady. I remember this story back in Sunday School about how between the Crucifixion and the Resurrection, Christ spent some time in Hell, rescuing the righteous, the ones that didn't belong. "Harrowing Hell," they called it. Guess you could say I'm just following an old tradition... harrowing Hell.

(Closing Voiceover)
Narrator: Centuries ago, Hell was reached by chalk-white horses pulling shuttered coaches; by Spanish galleons borne on black sails through uncharted seas. Legend has it Leonardo da Vinci was once commissioned to build a flying machine to carry souls to Hell, but it never returned from its maiden flight. But along this particular road to Hell lies redemption for the damned as well as for drivers who have found work... in the Twilight Zone.
