Lou: You gonna order something, kid?
Marty McFly: Ah, yeah... Give me a Tab.
Lou: Tab? I can't give you a tab unless you order something.
Marty McFly: All right, give me a Pepsi Free.
Lou: You want a Pepsi, pal, you're gonna pay for it!

Marty McFly: Clayton Ravine was named after a teacher. They say she fell in there a hundred years ago.
Doc: A hundred years ago? That's this year!
Marty McFly: Every kid in school knows that story 'cause we all have teachers we'd like to see fall into the ravine.

Dr. Emmett Brown: 1.21 jigawatts? 1.21 jigawatts! Great Scott!
Marty McFly: [following] What the hell is a jigawatt?

Marty McFly: 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?

Doc: Reach!
Engineer: Is this a holdup?
Doc: It's a science experiment!

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

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.

Buford "Mad Dog" Tannen: Then let's settle it, right now!
Buford's Gang Member #1: Uh, not now, Buford. Marshal's got our guns.
Buford "Mad Dog" Tannen: Like I said, we'll finish this tomorrow.
Buford's Gang Member #2: Tomorrow, we're robbing the Pine City Stage.
Buford "Mad Dog" Tannen: What about Monday? Are we doing anything Monday?
Buford's Gang Member #1: Uh, no, Monday would be fine. You can kill him on Monday.
Buford "Mad Dog" Tannen: I'll be back this way on Monday! We'll settle this then... right there... out in the street... in front of the Palace Saloon!
Marty McFly: Yeah, like when? High noon?
Buford "Mad Dog" Tannen: Noon? I do my killin' before breakfast! Seven o'clock!
Marty McFly: Eight o'clock. I do my killing after breakfast!

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

Doc

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

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

Biff Tannen

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.
