Marty McFly

If you guys ever have kids, and one of them, when he's eight years old, accidentally sets fire to the living room rug... go easy on him.

— Whoa. This is heavy.
— There's that word again. «Heavy». Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?

— What about all that talk about screwing up future events? The space-time continuum?
— Well, I figured, what the hell.

— You don't just walk into a store and buy plutonium. Did you rip that off?
— Of course. From a group of Libyans. They wanted me to build them a bomb. I took the plutonium and gave them a bomb casing full of pinball machine parts.

— Why, that's me! Look at me! I'm an old man! Thank God, I've still got my hair. What's this thing I'm wearing?
— This is a radiation suit.
— Radiation suit? Of course. 'Cause of all the fallout from the atomic wars.

I guess you guys aren't ready for that yet... but your kids are going to love it.

— Sounds heavy.
— Weight has nothing to do with it.

2015? You mean we're in the future?

— Oh, this is heavy, Doc. I mean, it's like I was just here yesterday.
— You were here yesterday, Marty.

Come on, Doc. Think about it. What are you gonna say to her? «I've got to go back to the future?» I mean, she's not gonna understand that, Doc. Hell, I'm in it with you, and I don't even understand it.

— Wait a minute. Wait a minute Doc, uh, are you telling me you built a time machine … out of a DeLorean?
— The way I see it, if you’re going to build a time machine into a car, why not do it with some style?

— «Hill Valley weather this Saturday night. Mostly clear, with some scattered clouds».
— Are you sure about this storm?
— Since when can weathermen predict the weather, let alone the future?

— What's your name, dude?
— Marty... Eastwood. Clint Eastwood.
— What kind of stupid name is that?
