Marty McFly: This is uh... This is heavy duty, Doc. This is great. Uh... does it run, like... on regular unleaded gasoline?
Dr. Emmett Brown: Unfortunately no, it requires something with a little more kick - plutonium.
Marty McFly: Uh... plutonium? Wait. Are you telling me that this sucker is nuclear?
Dr. Emmett Brown: Hey, hey, hey. Keep rolling. Keep rolling, there. No, no, no. This sucker's electrical, but I need a nuclear reaction to generate the 1.21 jigawatts of electricity I need.

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

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

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.
