Radio Announcer:
Doc: Are you sure about this storm?
Marty: Since when could the weatherman predict the weather, let alone the future.
Doc: You know Marty, I'm gonna be very sad to see you go. You've really made a difference in my life, you've given me something to shoot for. Just knowing, that I'm gonna be around to see 1985, that I'm gonna succeed in this. That I'm gonna have a chance to travel through time. It's going to be really hard waiting 30 years before I could talk to you about everything that's happened in the past few days. I'm really gonna miss you, Marty.
Marty: I'm really gonna miss you. Doc, about the future...
Doc: No! Marty, we've already agreed that having information about the future could be extremely dangerous. Even if your intentions are good, they could backfire drastically. Whatever you've got to tell me I'll find out through the natural course of time.
Marty:
Cop: Evening, Dr Brown, what's with the wire?
Doc: Oh, just a little weather experiment.
Cop: What you got under here?
Doc: Oh no, don't touch that. That's some new specialised weather sensing equipment.
Cop: You got a permit for that?
Doc: Of course I do.
Doc: Just a second, let's see if I could find it.
Marty: Do you mind if we park for a while?
Lorraine: That's a great idea. I'd love to park.
Marty: Huh?
Lorraine: Well, Marty, I'm almost 18 years old, it's not like I've never parked before.
Marty: What?
Lorraine: Marty, you seem so nervous, is something wrong?
Marty: No, no.
Marty: Lorraine, Lorraine, what are you doing?
Lorraine: I swiped it from the old lady's liquor cabinet.
Marty: Yeah well, you shouldn't drink.
Lorraine: Why not?
Marty: Because, you might regret it later in life.
Lorraine: Marty, don't be such a square. Everybody who's anybody drinks.
Marty: Jesus, you smoke too?
Lorraine: Marty, you're beginning to sound just like my mother!
Marvin: We're gonna take a little break but we'll be back in a while so, don't nobody go nowhere.
Lorraine: Marty, why are you so nervous?
Marty: Lorraine, have you ever, uh, been in a situation where you know you had to act a certain way but when you got there, you didn't know if you could go through with it?
Lorraine: Oh, you mean how you're supposed to act on a first date?
Marty: Ah well, sort of.
Lorraine: I think I know exactly what you mean.
Marty: You do?
Lorraine: You know what I do in those situations?
Marty: What?
Lorraine: I don't worry.
Lorraine: This is all wrong. I don't know what it is but when I kiss you, it's like kissing
Marty:
Lorraine: Someone's coming.
Biff: You cost 300 bucks damage to my car, you son of a bitch. And I'm gonna take it out of your ass.
Lorraine: Let him go, Biff, you're drunk.
Biff: Well lookie what we have here!
Biff: No, no, no, you're staying right here with me.
Lorraine: Stop it!
Biff: C'mon!
Lorraine: Stop it!
Biff: C'mon!
Marty: Leave her alone, you bastard!
Biff: You guys, take him in back and I'll be right there.
Biff: Well c'mon, this ain't no peep show!
Skinhead: Let's put him in there.
3-D: Yeah.
Skinhead: That's for messing up my hair.
