Back to the Future Part II (1989)
[In the year 2015] Doc Emmet Brown: The justice system moves swiftly, now that they've abolished all the lawyers.
Doc Emmet L. Brown: The time-traveling is just too dangerous. Better that I devote myself to study the other great mystery of the universe: women!
Lorraine Baines: Biff Tannen, I wouldn't marry you if you had a million dollars.
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.
Television announcer: Broadcasting beautiful views 24 hours a day: you're tuned to the Scenery Channel.
[Jennifers from two different times confront one another.] Young Jennifer: I'm old!!! Old Jennifer: I'm young!!!
[Flying above Biff in 1955.] Marty McFly: There he is, Doc! Let's land on him, we'll cripple his car. Doctor Emmett L. Brown: Marty, he's in a '46 Ford, we're in a DeLorean. He'd rip through us like we were tin foil.
Doc Emmet Brown: Marty! What in the name of Sir Isaac H. Newton happened here?
Doc Emmet Brown: No! It can't be! I just sent you back to the future! Marty McFly: You did, oh, I know, you did send me back to the future, but I'm back -- I'm back FROM the future. Doc Emmet Brown: Great Scott! [faints]
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.
