Marty McFly: Whoa... they really cleaned this place up. Looks brand-new.
Dr. Emmett Brown: Now, remember - according to my theory, you interfered with your parents first meeting. If they don't meet, they won't fall in love, they won't get married and they won't have kids. That's why your older brother's disappearing from that photograph. Your sister will follow, and unless you repair the damage, you'll be next.
Marty McFly: Sounds pretty heavy.
Dr. Emmett Brown: Weight has nothing to do with it.

arty 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 John F. Kennedy Drive.
Sam Baines: Who the hell is John F. Kennedy?

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.

[introducing his band] All right. We're the, uh... we're the Pinheads.

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!

Marty McFly: Ah, Jesus Christ! Jesus Christ, Doc, you just 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 is 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 1:21 am and zero seconds, we shall catch up with him and the time machine.

Wait, you don't understand. If you don't play there's no music. If there's no music they don't dance. If they don't dance they don't kiss and fall in love and I'm history.

Dr. Emmett Brown: Which one's your pop?
Marty McFly: [points him out getting beat up] That's him.
Dr. Emmett Brown: Maybe you were adopted.

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.

Dr. Emmett Brown

Marty McFly: Calvin? Wh... Why do you keep calling me Calvin?
Lorraine Baines: Well, that is your name, isn't it? Calvin Klein? It's written all over your underwear.

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

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.
