Marty McFly: Do you know where Riverside Drive is?
Sam Baines: It's on the other end of town, a block past Maple. East end of town.
Marty McFly: A block past Maple? That's, uh, that's John F. Kennedy Drive.
Sam Baines: Who the hell is John F. Kennedy?

[on the phone]
Marty McFly: You know, Doc, you left your equipment on all week.
Dr. Emmett Brown: My equipment. That reminds me, Marty. You better not hook up to the amplifier. There's a slight possibility of overload.
Marty McFly: Yeah, I'll keep that in mind.

Lorraine Baines: Kids, we're gonna have to eat this cake by ourselves. Your Uncle Joey didn't make parole again.
[drops the cake on the dining table. It reads "Welcome Home, Uncle Joey"]
Lorraine Baines: Think it would be nice if you all dropped him a line.
Marty McFly: Uncle "Jailbird" Joey?
Dave McFly: He's *your brother*, Mom.
Linda McFly: Yeah. I think it's a major embarrassment having an uncle in prison.
Lorraine Baines: We all make mistakes in life, children.

Dr. Emmett Brown: Oh, my God, they found me, I don't know how, but they found me. Run for it Marty.
Marty McFly: Who? Who?
Dr. Emmett Brown: Who do you think? The Libyans.
Marty McFly: Holy shit!

Dr. Emmett Brown: [the DeLorean has just made the first time-jump] Ah! What did I tell you? 88 miles per hour! The temporal displacement occurred exactly 1:20am and zero seconds!
Marty McFly: Ah, Jesus Christ! Jesus Christ, Doc, you disintegrated Einstein!
Dr. Emmett Brown: Calm down, Marty, I didn't disintegrate anything. The molecular structure of both Einstein and the car are completely intact.
Marty McFly: Then where the hell *are* they?
Dr. Emmett Brown: The appropriate question is, "*When* the hell are they?" You see, Einstein has just become the world's first time-traveler! I sent him into the future. One minute into the future to be exact. And at precisely 1:21am and zero seconds, we shall catch up with him and the time machine.

Great Scott!

Dr. Emmett Brown

[Marty and Doc observe George's incompetence in 1955]
Dr. Emmett Brown: Which one's your pop?
Marty McFly: [points him out] That's him.
[they see him getting kicked around by other school bullies]
George McFly: [has a 'kick me' sign on his back] Okay. Okay you guys. Ah-ha-ha-ha, very funny. You guys are being real mature.
Dr. Emmett Brown: Maybe you were adopted.

Marty McFly: [acting cool] Do you mind if we... park... for a while?
Lorraine Baines: That's a great idea. I'd love to park.
Marty McFly: Huh?
Lorraine Baines: Marty, I'm almost 18 years old. It's not like I've never parked before.
Marty McFly: What?
Lorraine Baines: Marty, you seem so nervous. Is something wrong?
Marty McFly: [trying to maintain composure] No... No.
[Lorraine takes a sip from a liquor bottle]
Marty McFly: [grabbing the bottle from Lorraine] Lorraine, Lorraine, What are you doin'?
Lorraine Baines: [starting to laugh] I swiped it from the old lady's liquor cabinet.
Marty McFly: Yeah, well, you shouldn't drink.
Lorraine Baines: Why not?
Marty McFly: Because you - you might regret it later in life.
Lorraine Baines: Marty, don't be such a square. Everybody who's anybody drinks.
[Marty takes a sip from Lorraine's bottle then spit-takes as he notices Lorraine lighting a cigarette]
Marty McFly: [nauseatingly] Geez! You smoke too?
Lorraine Baines: Marty, you're beginning to sound just like my mother!

Dr. Emmett Brown: Marty, I'm sorry. But the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning.
Marty McFly: [startled] What did you say?
Dr. Emmett Brown: A bolt of lighting. Unfortunately, you never know when or where it's ever gonna strike.
Marty McFly: We do now.
[hands Doc the "Save the Clock Tower" flyer]

[thinking Marty is an alien]
Sherman Peabody: It's already mutated into human form. Shoot it!
Old Man Peabody: [firing shotgun at barn] Take that, you mutated son of a bitch!

Things have certainly changed around *here*. I remember when this was all farmland as far the eye could see. Old man Peabody owned all of this. He had this crazy idea about breeding pine trees.

Biff Tannen: What are you looking at butthead?
Skinhead: Hey Biff, get a load of this guy's life preserver. Dork thinks he's gonna drown.
