Younger Dr. Emmett Brown: [running out of the room] 1.21 gigawatts? 1.21 gigawatts? Great Scott!
Marty McFly: [following] What-what the hell is a gigawatt?

[on the phone, as Marty plays "Johnny B. Goode"] Chuck. Chuck. It's Marvin - your cousin, Marvin BERRY. You know that new sound you're looking for? Well, listen to this.

Officer Reese: Hilldale, nothing but a breeding ground for tranks, lobos and zipheads.
Officer Foley: Yeah, they outta tear this whole place down.

George McFly: Uh... now Biff, I want make sure that we get two coats of wax this time. Not just one.
Biff Tannen: Just finishing up the second coat now.
George McFly: Now Biff, don't con me!
Biff Tannen: I-I'm-I'm sorry, Mr. McFly. I-I meant I was just starting on the second coat.
George McFly: Ahh... Biff. What a character. Always trying to get away with something. I've had to stay on top of Biff ever since High School. Although if it wasn't for him...

Marty McFly: I did? I- I mean he did?

Marty McFly: [under his breath] It's screen door on a submarine, you dork.

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.
