Character: Doc Emmett Brown

- Doc, but what about all this talk that you can not change the future? About the space-time continuum?
- Yes, I thought, to hell with him this continuum.

Doc of 1955: it Was a pleasure to chat with you. Maybe we'll see you in the future.
Doc from 1985: Or in the past.

- Doc, you can't just walk into a store and buy plutonium! You stole it?
- Of course! From a bunch of Libyan nationalists. They wanted me to build them a bomb, and I grabbed the plutonium under his arm and vanish!

- Yes, a severe case.
Again, this "bad case"? Perhaps in the future things get heavier? You got a problem with earth's gravity?

- Then tell me future boy who President of the United States in 1985?
- Ronald Reagan.
- Ronald Reagan? Actor? A Vice-President? Jerry Lewis?

- Cool.
- Again cool. And all that in the future cool. And something gentle do you have?

- Yes, a severe case.
The weight has nothing to do with it.

Wow, I've aged! Well, not completely bald... what is this on me?
- Is that a Devo suit.
Oh, Yes, of course! The consequences of global nuclear war.

Amazing... a portable TV Studio! No wonder your President's an actor. He always looked better on TV.

- Heh, cool, Doc! It's like I was here yesterday.
- You were here yesterday, Marty! Was! Amazing, isn't it?

Where we're going, we don't need roads.
