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.

Since you're new here, I'm gonna cut you a break... today. So, why don't you make like a tree... and get out of here.

Biff Tannen

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

Dr. Emmett Brown: You're late, do you have no concept of time?
Marty McFly: Hey c'mon, I had to change, you think I'm going back in that, that zoot suit? The old man really came through, it worked!
Dr. Emmett Brown: What?
Marty McFly: He laid out Biff in one punch! I never knew he had it in him! He never stood up to Biff in his life!

Don't worry. As long as you hit that wire with the connecting hook at precisely 88 miles per hour, the instant the lightning strikes the tower... everything will be fine.

Dr. Emmett Brown

[stands tall with a hand over his heart] Mayor Goldie Wilson. Like the sound of that.

Goldie Wilson


Goldie Wilson: No, sir! I'm gonna make something of myself. I'm going to night school. And one day I'm gonna be somebody!
Marty McFly: That's right, he's gonna be mayor!
Goldie Wilson: Yeah, I'm gonna... Mayor! Now that's a good idea! I can run for mayor.
Lou: A colored mayor, that'll be the day.
Goldie Wilson: You wait and see, Mr. Carruthers. I will be mayor! I'll be the most powerful man in Hill Valley. I'm gonna clean up this town.
Lou: Good. You can start by sweeping the floor.

Biff Tannen: And uh, where's my reports?
George McFly: Uh, well, I haven't finished those up yet, but you know I... I figured since they weren't due till...
Biff Tannen: Hello? Hello? Anybody home? Huh? Think, McFly. Think! I gotta have time to get 'em retyped. Do you realize what would happen if I hand in my reports in your handwriting? I'll get fired. You wouldn't want that to happen, would ya? Would ya?
George McFly: Of course not, Biff. I wouldn't want that to happen. Now, look. I'll finish those reports on up tonight and I'll run 'em on over first thing tomorrow. All right?

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

Biff Tannen

George McFly: I know what you're gonna say, son. And you're right, you're right. But uh... Biff just happens to be my supervisor, and I'm afraid I'm just no good at... confrontations.
Marty McFly: The car, Dad. I mean he wrecked it. He totaled it. I needed that car tomorrow night, Dad. Do you have any idea how important this is to me? Do you have any clue?
George McFly: I know, And all I can say is... I'm sorry.

Goldie Wilson: Say! Why do you let those boys push you around like that for?
George McFly: Well, they're bigger than me.
Goldie Wilson: Stand tall, boy. Have some respect for yourself. Don't you know if you let people walk over you now, they'll be walking over you for the rest of your life! Look at me. You think I'm gonna spend the rest of my life in this slop house?
Lou: Watch it, Goldie!

I'm sure in 1985 plutonium is available at every corner drugstore, but in 1955, it's a little hard to come by.
