Found the TZ reference here:
The best Twilight Zone episode ever filmed is about what happens when a huge flying saucer comes to Earth.
With great flourish, the creepy-looking visitors present a big book to the inhabitants of this planet. The friendly aliens then offer to take all interested parties off to a better world.
Meanwhile, as thousands queue up to depart a troubled world locked in Cold War, American scientists are working feverishly to decipher the big book from the aliens. Its title, if I remember correctly, is rather noble – “To Serve Man.”
Finally, the code is broken. As the spaceship is about to depart for another galaxy, with people lined up for the flight like so many cattle, a desperate scientist rushes to the scene.
“It’s a cookbook!” the code-breaker shouts. Unfortunately, it’s too late for mankind, which is about to take one giant step into the inter-galactic commodities market…
(ADD) More on the TZ reference:
“IN a famous episode of The Twilight Zone, advanced space aliens visit Planet Earth and promise an utopia for mankind. The jubilant humans are awed by the promised technological marvels-all diseases will be cured, all desires satisfied-and board spaceships in droves. A lone skeptical scientist discovers-too late-that the aliens’ how-to manual, To Serve Man, is not actually a guide to helping humanity, but ‘a cookbook! It’s a cookbook!’”
(ADD) “To Serve Man” …
Another quote from same site: “Actually, “To Serve Man” was a Twilight Zone episode, and one of the very best (“It’s a cookbook…it’s a cookbook” - very ably satrized in the first Naked Gun movie I might note).”

[li]Respectfully submitted for your perusal: a Kanamit. Height: a little over nine feet. Weight: in the neighborhood of three hundred and fifty pounds. Origin : unknown. Motives? Therein hangs the tale, for in just a moment we’re going to ask you to shake hands, figuratively, with a Christopher Columbus from another galaxy and another time. This is the Twilight Zone.[/li][/ul]
[li]Mr. Chambers! Don’t get on that ship! The rest of the book, To Serve Man, it’s… it’s a cookbook![/li][/ul]
[li]The recollections of one Michael Chambers, with appropriate flashbacks and soliloquy. Or more simply stated, the evolution of man, the cycle of going from dust to dessert, the metamorphosis from being the ruler of a planet to an ingredient in someone’s soup. It’s tonight’s bill of fare on the Twilight Zone.[/li][/ul]
