Lorraine Baines: Are you all right?
Marty McFly: I'm fine, I'm fine. It's just that you're so... big...
S. S. Strickland: Who?
[jabs Marty with shotgun threateningly]
Marty McFly: Marty McFly! Marty McFly! Don't you know, Mr... From school, sir!
S. S. Strickland: I've never seen you before, but you look to me like a slacker!
Marty McFly: Yeah! That's right! That's right, I am a slacker! Don't you remember, you gave me detention last week!
S. S. Strickland: Last week? The school burnt down six years ago! Now you got exactly three seconds to get off my porch with your nuts intact!
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!
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.
[watching chase unfold in 2015] There's something very familiar about all this.Old Biff
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!
Biff Tannen, I wouldn't marry you if you had a million dollars.Lorraine Baines
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.
Young Doc: No! It can't be; I just sent you back to the future!
Marty McFly: No, I know; you did send me back to the future. But I'm back ... I'm back from the future.
Young Doc: Great Scott! [faints]
Marty McFly: Doc! Doc! Doc!
Marty! What in the name of Sir Isaac H. Newton happened here?Doc
Doc: The time-traveling is just too dangerous. Better that I devote myself to study the other great mystery of the universe: women!
Marty McFly: [Reading newspaper in 2015] "Within two hours of his arrest, Martin McFly Jr. was tried, convicted and sentenced to fifteen years in the state penitentiary." In two hours?
Doc: The justice system works swiftly in the future now that they've abolished all lawyers.
