Stella Baines: He's a very strange young man.
Sam Baines: He's an idiot. Comes from upbringing. Parents are probably idiots too. Lorraine, if you ever have a kid that acts that way I'll disown you.

Marty McFly: 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.

Hey Dad, George. Hey, you on the bike!

Marty McFly

Biff Tannen: What are you looking at, butt head?
Skinhead: Hey Biff, get a load of this guy's life preserver. Dork thinks he's gonna drown.

Oh... one other thing. 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.

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.

Marty McFly: Do you mind if we... park... for a while?
Lorraine Baines: That's a great idea. I'd love to park.
Marty McFly: Huh?
Lorraine Baines: Marty, I'm almost 18 years old. It's not like I've never parked before.
Marty McFly: What?

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

Marty McFly: Mom... is that you?
Lorraine Baines: There, there now. Just relax.

Dr. Emmett Brown: Have them go on some sort of social...
Marty McFly: You mean like a date?
Dr. Emmett Brown: Right.
Marty McFly: Well, what kind of date? 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.

Jesus, George, it's a wonder I was ever born.

Marty McFly

Dr. Emmett Brown: Are those my clocks I hear?
Marty McFly: Yeah! Uh, it's 8 o'clock!
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.
