[on the phone while all the clocks chime at once]
Dr. Emmett Brown: Are those my clocks I hear?
Marty McFly: Yeah, it's 8:00.
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!
[hangs up, grabs his skateboard and rushes out]
Marty McFly: [Reading a letter he has just written] Dear Dr. Brown. On the night that I go back in time, you will be shot by terrorists. Please take whatever precautions are necessary to prevent this terrible disaster. Your friend, Marty.
[Writes the words "Do not open until 1985" on the envelope]
Dr. Emmett Brown: [reads the "Save the Clock Tower" flyer and reacts with hope] 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 p.m. next Saturday night! If... If we could 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!
[seeing a poster for the Enchantment Under the Sea dance]
Dr. Emmett Brown: Look! There's a rhythmic ceremonial ritual coming up.
Marty McFly: Of course! The Enchantment Under the Sea dance! They're supposed to go to this. That's where they kiss for the first time.
Dr. Emmett Brown: All right, kid. You stick to your father
like glue and make sure he takes her to that dance.
Lorraine Baines: Marty? Why are you so nervous?
Marty McFly: Lorraine. Have you ever been in a situation where you knew you had to act a certain way, but when you got there, you didn't know if you could go through with it?
Lorraine Baines: You mean like how you're supposed to act on a first date?
Marty McFly:
[stammering] Sort of.
Lorraine Baines: I think I know exactly what you mean. You know what I do in those situations?
Marty McFly: You do? What?
Lorraine Baines: I don't worry.
[kisses him hard]
Lorraine Baines: [Lorraine stops and pulls back, Marty is freaking out]
Lorraine
Baines: This is all wrong. I don't know what it is. But when I kiss you, it's like I'm kissing... my brother. I guess that doesn't make any sense, does it?
Marty McFly: Believe me, it makes perfect sense.
Dr. Emmett Brown: You've got to get your father and mother to interact in some sort of social...
Marty McFly: Wh-what? You mean like a date?
Dr. Emmett Brown: Right!
Marty McFly: What kind of date? I don't know. What do kids do in the '50s?
Dr. Emmett Brown: Well, they're your parents.
You must know them. What are their common interests? What do they like to do together?
Marty McFly: Nothing.
[Marty enters his house and sees Biff harrassing George]
Biff Tannen: I can't believe you'd loan me your car without telling me it had a blind spot. I could've been killed!
George McFly: Blind spot? Now, now, Biff, now I never noticed that the car had any blind spot before when I would drive it. Hi, Son.
Biff Tannen: What, are
you blind, McFly? It's there. How else do you explain that wreck out there?
George McFly: Biff, can I- Can I assume that your, uh, insurance is gonna pay for the damage?
Biff Tannen: My insurance? It's your car. Your insurance should pay for it. I wanna know who's gonna pay for this?
[shows his shirt]
Biff Tannen: I
spilled beer all over it when the car smashed into me. Who's gonna pay my cleaning bill?
Dr. Emmett Brown: Marty, I'm sorry, but the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning.
Marty McFly: [startled] What did you say?
Dr. Emmett Brown: A bolt of lightning. Unfortunately, you never know when or where it's ever gonna strike.
Marty McFly: We do now.
[hands Doc the "Save the Clock Tower" flyer]
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.
Linda McFly: [having "originally" - before Marty went back in time and altered the past - complained about not being very popular socially] If Paul calls, tell him I'm working late at the boutique tonight.
Dave McFly: Linda, first of all, I'm not your answering service; second of all, somebody named Greg or Craig called you just a little while ago.
Linda McFly: Well, which one was it, Greg or Craig?
Dave McFly: [a little impatiently] I don't know! I can't keep up of all of your boyfriends!
Skinhead: [throws Marty in the trunk of a car] That's for messing up my hair!
Band Member: What the hell you doing to my car?
3-D: Hey, beat it, spook. This don't concern you.
Marvin Berry: [four additional band members get out of the car] Who you calling "spook," peckerwood?
Skinhead: Hey, hey, listen,
guys... Look, I don't wanna mess with no reefer addicts, okay?
Marvin Berry: Get home to your mama, boy.
3-D: Biff, help!
[the band members chase the boys]
