George McFly:
Lorraine, my density has bought me to you.
Lorraine Baines:
What?
George McFly:
Oh, what I meant to say was...
Lorraine Baines:
Wait a minute, don't I know you from somewhere?
George McFly:
Yes. Yes. I'm George, George McFly. I'm your density. I mean... your destiny.


George McFly:
Last night, Darth Vader came down from planet Vulcan and told me that if I didn't take Lorraine out that he'd melt my brain.


Marty McFly:
Wait a minute, Doc. Ah... Are you telling me that you built a time machine... out of a DeLorean?
Dr. Emmett Brown:
The way I see it, if you're gonna build a time machine into a car, why not do it with some style?


[1955 Doc is watching a video of 1985 Doc]
Dr. Emmett Brown:
What on Earth's this thing I'm wearing?
Marty McFly:
Ah, this, this is a radiation suit.
Dr. Emmett Brown:
Radiation suit? Of course, because of all the fallout from the atomic wars.


[in the past, Marty observes his dad's incompetence]
Marty McFly:
Jesus, George, it was a wonder I was even born.


Mr. Strickland:
I noticed your band is on the roster for the dance auditions after school today. Why even bother, McFly? You don't have a chance, you're too much like your old man. No McFly ever amounted to anything in the history of Hill Valley!
Marty McFly:
Yeah, well, history is gonna change.


[repeated line]
Marty McFly:
If you put your mind to it, you can accomplish anything.


Biff Tannen:
Mr. McFly! Mr. McFly, this just arrived. Oh, Hi, Marty. I think it's your new book.
Lorraine Baines:
Oh, Honey. Your first novel!
George McFly:
Like I've always told you, you put your mind to it, you can accomplish *anything*.
Biff Tannen:
Oh, Marty... Marty, here's your keys. You're all waxed up, ready for tonight.
Marty McFly:
Keys?


Marty McFly:
Too loud. I can't believe it. I'm never gonna get a chance to play in front of anybody.
Jennifer Parker:
Marty, one rejection isn't the end of the world.
Marty McFly:
Nah, I just don't think I'm cut out for music.
Jennifer Parker:
But you're good, Marty, you're really good. And this audition tape of yours is great. You've gotta send it in to the record company. It's like Doc's always saying...
Marty McFly:
Yeah, I know, I know. "If you put your mind to it, you can accomplish anything".
[Marty notices two girls walk by and looks at them]
Jennifer Parker:
[turns Marty's head back to her] That's good advice, Marty.
Marty McFly:
Well, what if I take the tape in and they don't like it, what if they say I'm no good, what if they say "Get out of here kid. You've got no future." I just don't think I can handle that kind of rejection. Jesus I'm starting to sound like my old man.
Jennifer Parker:
Oh, come on.
Marty McFly:
[sees a tow truck pull up with a 4X4 Toyota on the flat bed] Check out that 4X4. That is hot. Someday Jennifer, someday, wouldn't it be great, take that truck up to the lake. Throw a couple of sleeping bags in the back. Lay out underneath the stars.
Jennifer Parker:
Stop it.
Marty McFly:
What?
Jennifer Parker:
Does your mom know about tomorrow night?
Marty McFly:
No, Get outta town! My mom thinks I'm goin camping with the guys. Look Jennifer, my mom would freak out if she knew I was going out with you and then I get this standard lecture how she never did that kind of stuff when she was a kid, I mean look, I think the woman was born a nun.
Jennifer Parker:
She's just trying to keep you respectable.
Marty McFly:
Well she's not doing a very good job.
Jennifer Parker:
Terrible.


Biff Tannen:
And uh, where's my reports?
George McFly:
Uh, well, I haven't finished those up yet, but you know I... I figured since they weren't due till...
Biff Tannen:
Hello? Hello? Anybody home? Huh? Think, McFly. Think! I gotta have time to get 'em retyped. Do you realize what would happen if I hand in my reports in your handwriting? I'll get fired. You wouldn't want that to happen, would ya? Would ya?
George McFly:
Of course not, Biff. Nah, I wouldn't want that to happen. Now, look. I'll, uh, finish those reports on up tonight and I'll run 'em on over first thing tomorrow. All right?
Biff Tannen:
Eh, not too early. I sleep in Saturdays. Oh, McFly, your shoe's untied.
[jabs his finger up to George's face]
Biff Tannen:
Don't be so gullible, McFly. Got the place fixed up nice-o, McFly.


Marty McFly:
[being chased by terrorists] Let's see if you bastards can do 90.


[concerning his audition tape]
Marty McFly:
What if I send in the tape and they don't like it? I mean, what if they say I'm no good? What if they say "Get outta here, kid. You got no future."? I mean, I just don't think I can take that kind of rejection. Jesus, I'm starting to sound like my old man!
