Boy Dancer: Hey George, heard you laid out Biff, nice going!
Girl Dancer: George, you ever think of running for class president?
Marvin: Chuck, Chuck, its' Marvin. Your cousin, Marvin Berry! You know that new sound you're looking for? Well, listen to this!
Marty: I guess you guys aren't ready for that yet. But your kids are gonna love it.
Marty: Lorraine!
Lorraine: Marty, that was very interesting music.
Marty: Uh, yeah.
Lorraine: I hope you don't mind but George asked if he could take me home.
Marty: Great! Good, good, Lorraine. I had a feeling about you two.
Lorraine: I have a feeling too.
Marty: Listen, I gotta go but I wanted to tell you that it's been...educational.
Lorraine: Marty, will we ever see you again?
Marty: I guarantee it.
George: Well, Marty, I want to thank you for all your good advise, I'll never forget it.
Marty: Right, George. Well, good luck you guys.
Marty: Oh, one other thing, if you guys ever have kids and one of them when he's eight years old, accidentally sets fire to the living room rug, go easy on him.
George:
Lorraine: Marty, such a nice name.
Doc: Damn, where is that kid? Damn. Damn, damn.
Doc: You're late, do you have no concept of time?
Marty: Hey c'mon, I had to change, you think I'm going back in that, that zoot suit? The old man really came through, it worked!
Doc: What?
Marty: He laid out Biff in one punch! I never knew he had it in him! He never stood up to Biff in his life!
Doc: Never?
Marty: No, why, what's the matter?
Doc: All right, let's set your destination time. This is the exact time you left. I'm gonna send you back at exactly the same time. It'll be like you never left.

Marty: Right.
Doc: Well, I guess that's everything.
Marty: Thanks.
Doc: Thank you.
Doc: In about 30 years.
Marty: I hope so.
Doc: Don't worry. As long as you hit that wire with the connecting hook at precisely 88 miles per hour, the instance the lightning strikes the tower, everything will be fine.
Marty: Right.
Doc: What's the meaning of this?
Marty: You'll find out in 30 years.
Doc: It's about the future, isn't it?
Marty: Wait a minute!
Doc: It's information about the future, isn't it!
Doc: I warned you about this kid. The consequences could be disastrous!
Marty: Now that's a risk you'll have to take! Your life depends on it!
Doc: No, I refuse to accept the responsibility!
Marty: In that case, I'll tell you straight out.
Doc: Great Scott! You get the cable, I'll throw the rope down to you.
Marty: Right, I got it.
Doc: Ahh, hoo ooh, ah!
Marty: Doc!
Doc: C'mon, c'mon let's go.
Marty: All right, take it up, go.
Marty: Doc!
Doc: Huh?
Marty: I have to tell you about the future!
Doc: Huh?
Marty: I have to tell you about the future!
Doc: Ahh!
Marty: On the night I go back in time, you get...
Marty: Doc!
