- 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.
- [last lines]
- Moe Stein: Today's letter is from little Sam Beckett in Elk Ridge, Indiana. Sam writes: "Dear Captain Galaxy. Could you please explain your theory of time travel to us?" Well, Sam. Our lifetimes are like a piece of string. But... if you roll the string up into a ball, all the days of your life...
- Admiral Al Calavicci: [on Sam's 'Future Boy' costume] Don't tell me, let me guess: you've been invited to a costume party, and you're going as a baked potato.
- Ben Harris: Has the whole world gone crazy? Just because the Russians put a satellite in space doesn't mean you two get to go into orbit too!
- Moe Stein: I just don't want these kids growing up thinking that the future holds nothing but violence.
- Ben Harris: Don't be ridiculous. Kids love violence!
- Moe Stein: Because we tell them to love it. We should be teaching them to dream. To see the future for its possibilities, not its limitations. And you write me a script like that, and I will shout it from the rooftops!
- Dr. Sam Beckett: I do admit that Mr. Stein did try to build a time machine. But if you had sat there twelve years ago, and told me that the Russians would be the first ones to orbit a satellite around the Earth, I would've called you crazy. But two days ago, they did it. So, who's to say that... twelve years from now, say 1969, maybe men will be walking on the moon, or maybe Moe Stein will be traveling in time. Your Honor. Moe Stein is a dreamer. Are we going to punish people for that? Because if we are... you're gonna need a much bigger room than this.
- Dr. Sam Beckett: [referring to Moe] We don't know that this guy is crazy. Right? I mean, look at me. I'm standing here, I'm dressed like a giant TV dinner talking to a hologram! Now, what does that make me?
- Admiral Al Calavicci: Eccentric.
- Dr. Sam Beckett: What, what happened?
- Admiral Al Calavicci: Huh? What d'you mean?
- Dr. Sam Beckett: Did somebody die?
- Admiral Al Calavicci: Did somebody d... Oh, oh, you mean my suit. Oh. No. No. I have to make a court appearance. My third wife is suing me... No. Fourth? Fifth? My fourth wife is suing me for more alimony payments, and the lawyer says it'd be better if I appeared a little...
- Dr. Sam Beckett: Grown up.
- Admiral Al Calavicci: [sarcastic] No, boring.
- [Sam and Al are debating whether Moe is crazy or not]
- Admiral Al Calavicci: He's 65 years old. I mean, who in his right mind is gonna start riding the rails when he's 65?
- Dr. Sam Beckett: You would - if there were a cute girl on board.
- Admiral Al Calavicci: Oh, uh, yeah, well, I would.
- Dr. Sam Beckett: Irene. Moe was just telling me how much he was looking forward to meeting with Dr. Scanlon.
- Irene Kiner: Sandler.
- Dr. Sam Beckett: Sandler. Right.
- Irene Kiner: Is that true?
- Moe Stein: No. I'd rather have a tooth drilled without Novocaine.
