Biff: Calvin Klein?
He grabs Lorraine by her shoulders and turns her to face him.
Biff: No, that's not OK. You're going with me, understand?
Lorraine: Get your cooties off of me!
Biff: When are you going to get it through that thick skull of yours Lorraine, you're my girl!
Lorraine: Biff Tannen, I wouldn't be your girl even if... (pause) even if you had a million dollars!
Irony, although Lorraine doesn't know it! She kicks Biff in the leg.
Biff: Argh!
Then she hits him over the head with the box.
Biff: Oh!
Lorraine and Babs run off. Biff runs into the middle of the road, causing a car to swerve slightly to avoid hitting him.
Biff: Yes you will, Lorraine! It's you and me, Lorraine!
A car narrowly misses Biff.
Car Driver: Watch your back!
Biff: It's meant to be! Someday you'll marry me! Someday you'll be my wife!
Biff turns to his car after Lorraine and Babs run off to see 2015 Biff in his car. 1955 Biff doesn't recognise him as his future self.
2015 Biff: You always had your way with women, Biff.
1955 Biff: Get the hell outta my car, old man!
2015 Biff: Do you want to marry that girl, Biff? I can help make it happen.
1955 Biff: Oh yeah. And who are you? Miss Lonely Hearts?
2015 Biff: Just get in the car, butthead.
1955 Biff: Who are you calling butthead, butthead?
2015 Biff starts the car. 1955 Biff is surprised.
1955 Biff: How did you know how to do that? Nobody could start this car but me.
2015 Biff: Just get into the car, Tannen. Today's your lucky day.
Cut to the Tannen driveway. The car, driven by 2015 Biff, drives up towards the garage. The backs of the heads of both Biffs are visible.
1955 Biff: (v.o) Hey, hey, hey, hey, watch where you're going old man! If you break this car I'm gonna kill you!
The car enters the garage and 2015 Biff stops it. His face is visible, 1955 Biff is facing away.
1955 Biff: This cost me 300 bucks!
2015 Biff: Would you shut up about the car?
1955 Biff: Ay, and another thing, how do you know where I live?
2015 Biff: Let's just say we're related Biff, and that being the case I got a little present for you.
During the following Marty peers up from the back of the car to witness what's going on - he is not seen.
2015 Biff: (continued) Something that'll make you rich. You wanna be rich, don't ya?
1955 Biff: Oh yeah, sure, right, that's rich, ha ha, you're gonna make me rich!
2015 Biff: You see this book?
Marty ducks down again.
2015 Biff: (continued) This book tells the future. It tells the events of every major sports event til the end of the century. Football, baseball, horse races, boxing....the information in here is worth millions, and I'm giving it to you.
He passes the book to 1955 Biff. Obviously 1955 Biff thinks this is a load of rubbish.
1955 Biff: Well, that's very nice, thank you very much. Now why don't you make like a tree and get out of here?
2015 Biff gives 1955 Biff a slap across the head.
2015 Biff: It's leave, you idiot! "Make like a tree, and leave." You sound like a damn fool when you say it wrong!
1955 Biff: Alright then, leave!
1955 Biff throws the book in the back of the car. 2015 Biff catches it.
1955 Biff: And take your book with you!
2015 Biff: Don't you get it? You could make a fortune with this book, let me show you.
2015 Biff turns on the radio. During the following he's looking through the sports almanac to find the result.
Radio Announcer: (v.o) UCLA trail 17 to 16! It's 4th and 11 with only 18 seconds left of this game. I'd say it's all over for UCLA!
2015 Biff: Bet you a million bucks UCLA win at 19 to 17.
