Tales from the Darkside Season 4 Episode 15

(Rose is in the box, on which Charlie is putting a few "finishing touches")
Charlie: There, at last. It works!
Rose: Oh, Charlie... if it works now, it'll break later; and if it doesn't break, nobody would want it; and if anybody did want it, somebody else would already own the patent...
(Hh shuts the lid, cutting her off, then returns the box to Satan's uncle/the Deliveryman.)
Deliveryman: Thanks, Charlie. You say it can't be opened now?
Charlie: You'd have to destroy that box before you could open it now.

Postman: I checked with my nephew, it says you're a pickup, not a drop off, let me check.
(Charles tries to stab the postman)
Charles: I can't do it, Rose.
(Rose takes the knife and plunges it into the postman's back, the postman turns to Rose with the open box)
Postman: Ah yes, Thou shalt not take thy Lord's name in vain, thou shalt not covet thy neighbor's possessions, and thou shalt not kill. No wonder you're a pickup.

Postman: Isn't there anything you want, Charles? Your wife has made a lot of requests but I don't remember you asking for anything. Would you like to be young, I mean really young, pretty girls and fast cars?
Charles: The only thing I want is to invent something that can help people. That's sort of always been my dream.
