Moe Stein:
[on his theory of time travel] Time is like a piece of string. One end of the string is birth, the other is death. You put them together, and your life is a loop.

Admiral Al Calavicci:
Sam, that's your theory!

Moe Stein:
If I can travel fast enough along the loop, I will eventually end up back at the beginning of my life.

Admiral Al Calavicci:
He-he's almost got it.

Dr. Sam Beckett:
Uh, well, what... Let me ask you, what would happen if, um, you would ball the string, right? And then each day of your life... would touch another day. And then... you could travel from one place on the string to another, thus enabling you to move back and forth within your own lifetime, maybe.

Moe Stein:
That's it. That's it! Then I could actually...

Dr. Sam Beckett:
Quantum leap?

Moe Stein:
Quantum leap. I like that. I like that a lot.
