Land of the Lost (1974–1977)
[The alien Enik has made a startling discovery about the temporal doorway that has led him and the Marshalls to this world]
Enik: I cannot leave here. Nothing can leave here, unless an object of equal mass and temporal energy enters.
Will Marshall: Well, that means we can't leave either, unless three other people come in.
Enik: Yes, but there is more. You should not be here at all. Your presence here is the source of my problem. Look...
[Enik opens the time doorway onto a view of the Grand Canyon]
Will Marshall: It's Earth! Enik, if I had a parachute I could jump through!
Enik: Wait, there is more.
[Next Will sees himself, Rick, and Holly]
Will Marshall: That's us, on the river!
Enik: Pay attention now, this is the troubling part.
Will Marshall: That's the rapids we were on.
[The time doorway replays - via stock footage of the show's title sequence - Rick, Will, and Holly being swallowed into a cavern by a monstrous earthquake, descending down underground rapids, and plunging down a monstrous waterfall - but Will notices an anomoly the audience cannot see]
Will Marshall: Enik... where's the mist for the doorway?
Enik: I do not know
[Will now realizes what Enik means by his earlier comments]
Will Marshall: We... we were all killed. Weren't we.
Enik: Obviously. You should not be here now.
Will Marshall: It's funny - I've walked this way hundreds of times and I've never seen this pylon.
Enik: Nor I, Will Marshall. And I have been in this valley many times longer than you.
Cha-Ka: Cha-Ka think it's *new* pylon!
Will Marshall: Either that, Cha-Ka, or it's been invisible all this time.
Enik: That is not logical.
Will Marshall: Now, Enik, if you've been in the Land of the Lost that much longer than we have, you ought to know by now that not everything here is logical.
Enik: That is logical.
