Mystery Science Theater 3000, Season 4

Narrator:
As if a switch had been turned, as if an eye had been blinked as if some phantom force in the universe had made a move eons beyond our comprehension...

Tom Servo:
As if we cared.

Narrator:
Suddenly, there was no trail. There was no giant, no monster, no thing called Douglas to be followed. There was nothing in the tunnel but the puzzled men of courage who suddenly found themselves alone with the shadows and darkness!

Joel:
Oh, the joke's on us!

Crow:
Boooooo!
