Western Union Man: Kid, you all right? You need any help?
Marty McFly: There's only one man who can help me.

Marty McFly: Are you two related?
Biff Tannen: Hello? Hello? Anybody home? What do you think? Griff just called me Grandpa for his health?

Doc: Time circuits on.
Marty McFly: Time circuits on? What do you mean "Time Curcuits on"? Doc, we're not going back now!
Doc: Yep.
Marty McFly: Doc, What about Jennifer? What about Einstein? We can't just leave them here.
Doc: Don't worry, Marty. Assuming we succeed in our mission, this alternate 1985 will be changed back into the real 1985, instantaneously transforming around Jennifer and Einie. Jennifer and Einie will be fine, and they'll have absolutely no memory of this horrible place.
Marty McFly: Doc... what if we don't succeed?
Doc: We must succeed.

Young Doc: Nice talking to you. Maybe we can bump into each other sometime again in the future.
Older Doc: Or in the past.

S. S. Strickland: So you're the son of a bitch who's been stealing my newspapers.
Marty McFly: Mr. Strickland! It- it- it's me, sir. Marty McFly!

'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.

Marty McFly, Jr.: Hey, Gram, could you just stuff the whole thing in my mouth?
Middle-Aged Marty: Don't you be a smart-ass!

I wasn't strong enough to save you mum. I wasn't strong enough, but I promise I won't fail again.

Marty McFly: That's right, Doc. November 12, 1955.
Doc: Unbelievable that old Biff could have chosen that particular date. It could mean that, that point in time inherently contains some sort of cosmic significance. Almost as if it were the junction point for the entire space-time continuum. On the other hand, it could just be an amazing coincidence.

Grandma Tannen: Biff, Biff, where you going, Biff?
Biff Tannen: I told you, grandma, I'm goin' to the dance.
Grandma Tannen: When are you coming home?
Biff Tannen: I'll get home, when I get home.
Grandma Tannen: Don't forget to turn off the garage lights!

[watching chase unfold in 2015] There's something very familiar about all this.

Old Biff

Obi-Wan: Just relax, concentrate.
Anakin: What about Padme?
Obi-Wan: She seems to be on top of things.
