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

Luke: If I don't make it back, you're the only hope for the Alliance.
Princess Leia: Luke, don't talk that way. You have a power I don't understand and could never have.
Luke: You're wrong, Leia. You have that power too. In time you'll learn to use it as I have. The Force runs strong in my family. My father has it. I have it. And... my sister has it. Yes. It's you, Leia.
Princess Leia: I know. Somehow, I've always known.

Dr. Emmett Brown: This is it! This is the answer. It says here... that a bolt of lightning is going to strike the clock tower at precisely 10:04 pm, next Saturday night! If we can somehow... harness this lightning... channel it... into the flux capacitor... it just might work. Next Saturday night, we're sending you back to the future!

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

Dr. Emmett Brown

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.

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

Biff Tannen

Leia: I thought you knew this person.
Chewbacca: [barks something at Han]
Han Solo: Well, that was a long time ago, I'm sure he's forgotten about that.

Princess Leia: I hope you know what you're doing.
Han Solo: Yeah, me too.
