Dr. Emmett Brown: If my calculations are correct, when this baby hits 88 miles per hour... you're gonna see some serious shit.
Marty McFly: [57:58] Whoa. Wait a minute, Doc. Are you trying to tell me that my mother has got the hots for me?
Dr. Emmett Brown: Precisely.
Marty McFly: Whoa. This is heavy.
Dr. Emmett Brown: There's that word again. "Heavy." Why are things so heavy in the future? Is there a problem with the Earth's
gravitational pull?
Marty McFly: Wait a minute. 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?*
Marty McFly: [43:42] Calvin? Wh... Why do you keep calling me Calvin?
Lorraine Baines: Well, that is your name, isn't it? Calvin Klein? It's written all over your underwear.
[in the past, Marty observes his dad's incompetence]
Marty McFly: Jesus, George, it was a wonder I was even born.
[Marty and Doc observe George's incompetence in 1955]
Dr. Emmett Brown: Which one's your pop?
Marty McFly: [points him out] That's him.
[they see him getting kicked around by other school bullies]
George McFly: [has a "kick me" sign on his back] Okay. Okay, you guys. Ah-ha-ha-ha. Very funny. You guys are being real
mature.
Dr. Emmett Brown: Maybe you were adopted.
[Dr. Emmett Brown is doubting Marty McFly's story about that he is from the future]
Dr. Emmett Brown: Then tell me, future boy, who's President of the United States in 1985?
Marty McFly: Ronald Reagan.
Dr. Emmett Brown: Ronald Reagan? The actor?
[chuckles in disbelief]
Dr. Emmett Brown: Then
who's vice president? Jerry Lewis?
[rushing out and down a hill toward his laboratory]
Dr. Emmett Brown: I suppose Jane Wyman is the First Lady!
Marty McFly: [following Doc] Whoa. Wait, Doc!
Dr. Emmett Brown: And Jack Benny is secretary of the treasury.
Marty McFly: [outside the lab door] Doc,
you gotta listen to me.
Dr. Emmett Brown: [opens the door to the lab] I've had enough practical jokes for one evening. Good night, future boy!
[closes the door leaving Marty outside]
Marty McFly: No, wait, Doc. Doc. The-the-the bruise on your head, I know how that happened. You told me the whole story. You were standing on your toilet and you
were hanging a clock, and you fell and you hit your head on the sink. And that's when you came up with the idea for the flux capacitor,
[somberly]
Marty McFly: which is what makes time travel possible.
[Doc opens the door and looks at Marty with a stunned look on his face]
[addressing the shocked expressions at the dance after playing a wild heavy metal guitar solo]
Marty McFly: I g-guess you guys aren't ready for that yet. But your kids are gonna love it.
[Lorraine's parents are talking about Marty McFly, Lorraine's future son]
Stella Baines: He's a very strange young man.
Sam Baines: He's an idiot. Comes from upbringing. His parents are probably idiots, too. Lorraine, you ever have a kid who acts that way, I'll disown you.
George McFly: Lou, give me a milk.
[dramatic pause]
George McFly: Chocolate.
[Marty places headphones over his father's ears and wakes him up by playing Van Halen music at full blast. George wakes up screaming - Marty pauses the music. George looks up to see Marty, who is unrecognizable because he is wearing a radiation suit]
George McFly: Who are you?
Marty McFly: [after giving him another earful of loud rock music] Silence,
Earthling. My name is Darth Vader. I am an extraterrestrial from the planet Vulcan!
[makes Live Long and Prosper sign with his hand]
