George McFly: Lou. Give me a milk… Chocolate.
Marty McFly: Calvin? 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.
Dr. Emmett Brown: Don’t worry. As long as you hit that wire with the connecting hook at precisely 88mph the instant the lightning strikes the tower… Everything will be fine.
Dr. Emmett Brown: Tell me, “Future Boy”, who’s President in the United States in 1985?
Marty McFly: Ronald Reagan.
Dr. Emmett Brown: Ronald Reagan? The actor? Then who’s Vice President? Jerry Lewis? I suppose Jane Wyman is the First Lady!
Marty McFly: Whoa! Wait! Doc!
Dr. Emmett Brown: And Jack Benny is Secretary of the Treasury.
Marty McFly: Wait a minute, Doc, are you trying to tell me that my mother has got the hots for me?
Dr. Emmett Brown: Precisely.
Marty McFly: Whoa, this is heavy.
Dr. Emmett Brown: There’s that word again; “heavy.” Why are things so heavy in the future? Is there a problem with the earth’s gravitational pull?
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!
George McFly: Do you really think I oughta swear?
Marty McFly: Yes, definitely. Goddamn it George, swear.
Marty McFly: [watching a Honeymooners episode in 1955.] Hey, hey, I’ve seen this one. I’ve seen this one. This is a classic. This is, uh, where Ralph dresses up as a man from space.
Milton Baines: What do you mean, you’ve seen this? It’s brand new.
Marty McFly: Yeah, well, I saw it on a…rerun.
Milton Baines: What’s a rerun?
Marty McFly: You’ll find out.
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.
George McFly: Hey, you! Get your damn hands off her!
Marty McFly: 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.
Marty McFly: Wait a minute, Doc. Ah… Are you telling me that you built a time machine… Out of a DeLorean?
Dr. Emmett Brown: The way I see it, if you’re gonna build a time machine into a car, why not do it with some style?
Biff Tannen: I have your car towed all the way to your house and all you’ve got for me is *lite* beer?
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 John F. Kennedy Drive.
Sam Baines: Who the hell is John F. Kennedy?
Dr. Emmett Brown: This sucker’s electrical. But I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need.
Marty McFly: Doc, you don’t just walk into a store and buy plutonium. Did you rip that off?
Dr. Emmett Brown: Shhhhhh. Of course. From a group of Libyan nationalists. They wanted me to build them a bomb, so I took their plutonium and in turn, gave them a shiny bomb-casing full of used pinball machine parts!
Dr. Emmett Brown: Well, they’re your parents you must know them. What are their common interests? What do they like to do together?
Marty McFly: Nothing.
Lorraine Baines: Will we ever see you again?
Marty McFly: I guarantee it.
Lorraine Baines: Our first television set. Dad just picked it up today. Do you have a television?
Marty McFly: Well, yeah! You know we have… Two of them.
Milton Baines: Wow! You must be rich!
Stella Baines: Oh, honey, he’s teasing you. Nobody has two television sets.
Dr. Emmett Brown: No wonder your president has to be an actor, he’s gotta look good on television.
Sam Baines: Stella! Another one of these damn kids jumped in front of my car! Come on out here and help me take him in the house!
