arty 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: 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.

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.

Stella Baines: Marty, you look so familiar to me. Do I know your mother?
Marty McFly: Yeah, I think maybe you do...

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

Marvin Berry

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.

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

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!

Roads? Where we're going we don't need... roads.

Dr. Emmett Brown

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

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!
