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

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?

[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.

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

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

I have your car towed all the way to your house and all you've got for me is *lite* beer?

Biff Tannen

Chuck. Chuck. It's Marvin - your cousin, Marvin BERRY. You know that new sound you're looking for? Well, listen to this!

Marvin Berry

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.

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