Younger Dr. Emmett Brown: [running out of the room] 1.21 gigawatts? 1.21 gigawatts? Great Scott!
Marty McFly: [following] What-what the hell is a gigawatt?

You'll have to forgive the crudeness of this model, I didn't have time to paint it or build it to scale.

Dr. Emmett Brown

[to Uncle Joey as a baby, playing in his playpen] So you're my Uncle Joey. Better get used to these bars, kid.

Marty McFly

Jennifer Parker: Dr. Brown, I brought this note back from the future and now it's erased.
Doc: Of course it's erased.
Jennifer Parker: But what does that mean?
Doc: It means your future hasn't been written yet. No one's has. Your future is whatever you make it. So make it a good one, both of you.
Marty McFly: We will, Doc.

Marty, we all have to make decisions that affect the course of our lives. You've got to do what you've got to do. And I've got to do what I've got to do.

Doc

Bartender: In about ten minutes, he's gonna be as sober as a priest on Sunday.
Marty McFly: Ten minutes? Why do we have to cut these things so damn close?

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 shoddy bomb-casing full of used pinball machine parts! Come on! Let's get you a radiation suit. We must prepare to reload.

George McFly: Lou. Give me a milk...
[dramatic pause]
George McFly: Chocolate.

George McFly: Do you really think I oughta swear?
Marty McFly: Yes, definitely. Goddamn it George, swear.

Marty McFly: Listen, you got a back door to this place?
Bartender: Yeah, it's in the back.

Dr. Emmett Brown: Are those my clocks I hear?
Marty McFly: Yeah! Uh, it's 8 o'clock!
Dr. Emmett Brown: Perfect! My experiment worked! They're all exactly 25 minutes slow!
Marty McFly: Wait a minute. Wait a minute. Doc... Are you telling me that it's 8:25?
Dr. Emmett Brown: Precisely.
Marty McFly: Damn! I'm late for school.

Dr. Emmett Brown: 1.21 jigawatts? 1.21 jigawatts! Great Scott!
Marty McFly: [following] What the hell is a jigawatt?
