What is said at the end of a Twilight Zone episode?

Every episode has a different closing narration, but it always end with the words Twilight Zone.
A few examples:
= The Shelter closing narration is : = " No moral, no message, no prophetic tract: Just a simple statement of fact. For civilization to survive, the human race has to remain civilized. Tonight's very small exercise in logic, from the Twilight Zone.


= The Monsters Are Due on Maple Street closing narration is: =

" The tools of conquest do not necessarily come with bombs and explosions and fallout. There are weapons that are simply thoughts, attitudes, prejudices to be found only in the minds of men. For the record, prejudices can kill, and suspicion can destroy, and the thoughtless, frightened search for a scapegoat has a fallout all of its own; for the children, and the children yet unborn. And the pity of it is that these things cannot be confined to The Twilight Zone.

"
= The Masks closing narration: =
Mardi Gras incident, the dramatis personae being four people who came to celebrate and in a sense let themselves go. This they did with a vengeance. They now wear the faces of all that was inside them and they'll wear them for the rest of their lives, said lives now to be spent in shadow. Tonight's tale of men, the macabre and masks on the Twilight Zone.


= The Howling Man closing narration is: =
Ancient folk saying: 'You can catch the Devil, but you can't hold him for long.' Ask Brother Jerome. Ask David Ellington. They know, and they'll go on knowing to the end of their days and beyond--in the Twilight Zone.
