Doc: Marty, I gave you explicit instructions not to come here but to go directly back to 1985.
Marty McFly: I know, Doc.
Doc: But it's good to see you, Marty.

Marty, you can't go losing your judgment every time someone calls you a name. It's exactly what causes you to get into that accident in the future.

Doc

Marty! What in the name of Sir Isaac H. Newton happened here?

Doc

Hey, McFly. I thought I told you never to come in here.

Biff Tannen

Don't worry. As long as you hit that wire with the connecting hook at precisely 88mph the instant the lightning strikes the tower... everything will be fine.

Dr. Emmett Brown

Biff Tannen: That's about as funny as a screen door on a battleship.
Marty McFly: [under his breath] It's screen door on a submarine, you dork.

Clara was one in a million. One in a billion. One in a googolplex!

Doc

Great Scott!

Dr. Emmett Brown

Buford "Mad Dog" Tannen: You owe me money, blacksmith.
Doc: How do you figure?
Buford "Mad Dog" Tannen: My horse threw a shoe. And seeing as you was the one who done the shoeing, I say that makes you responsible.
Doc: Well, since you never paid me for that job, I say that makes us even!
Buford "Mad Dog" Tannen: Wrong! See I was ON my horse when it threw the shoe and I got throwed OFF! And THAT caused me to bust a perfectly good bottle of fine Kentucky red-eye. So, the way I figure it, blacksmith, you owe me five dollars for the whiskey and $75 for the horse.

Dr. Emmett Brown: Oh, my God, they found me, I don't know how, but they found me. Run for it Marty.
Marty McFly: Who? Who?
Dr. Emmett Brown: Who do you think? The Libyans.
Marty McFly: Holy shit!

'Ronald Reagan' Video Waiter: Welcome to the Cafe 80's, where it's always morning in America, even in the afternoon. Our special today is mesquite-grilled sushi...
'Ayatollah Khomeini' Video Waiter: [interrupts] You must have the hostage special!
Marty McFly: Hey, hey, hey, hey, guys, hey, hey! All I want is a Pepsi.

Young Biff: Why don't you make like a tree and get out of here?
Old Biff: It's leave, you idiot! "Make like a tree, and leave." You sound like a damn fool when you say it wrong.
Young Biff: All right then, leave! And take your book with you!
