1955 Marty: Lorraine!
Lorraine: Marty, that was very interesting music.
(Note: This line was said slightly differently in Part 2 than in Part 1, as they re-shot the scene so that George was not included in the frame.) 1985 Marty watches this through the door.
Lorraine: I hope you don't mind but George asked if he could take me home.
1955 Marty: Great good, good, Lorraine. I had a feeling about you two.
Lorraine: I have a feeling too.
Biff appears at the door next to 1985 Marty, who is still watching them.
Biff: Hey butthead! You think that stupid disguise will get by me? Let's have it out. You and me, right now.
Marty: No thanks.
He starts to walk away.
Biff: What's the matter, where are you going?
Inside, 1955 Marty heads for the door, and then turns back to the couple.
1955 Marty: Oh, one other thing.....
Outside:
Biff: Are you, chicken? That's it, isn't it? Nothing but a little chicken.
Marty turns around.
Marty: Nobody calls me chick-
1955 Marty exits the gym, slamming the door on his future self's head and causing 1985 Marty to fall over. Neither Marty sees the other, and Biff luckily doesn't see that there's two of them. Biff turns to 1985 Marty. He can sees that Marty has the almanac.
Biff: What the hell?
He takes the almanac.
Biff: You steal my stuff?
He kicks Marty in the stomach.
Marty: Whoa!
Biff: And this one's for my car!
He kicks Marty again. Marty watches Biff get into his car. Marty gets up, minus his hat (he just leaves it there) and tries to follow Biff, but Biff drives off. Marty heads for the high school roof by running up the stairs, where he sees Doc with the DeLorean.
Marty: Doc? Doc, I blew it. Biff nailed me, he took the book and he drove away with it in his car. It's my fault Doc, I should have gotten out of there sooner.
Doc: No time for that now, which way did he go?
Marty: (pointing) East, towards the River Road Tunnel.
Doc: Get in!
Cut to the road outside Hill Valley. The DeLorean flies above Biff's car, unseen. Marty gets out the binoculars.
Marty: (through binoculars) There he is, Doc. Let's land on him and cripple his car.
Cut to normal view of Marty and Doc.
Doc: Marty, he's in a '46 Ford. We're in a DeLorean. He'd rip through us like we were tin foil.
Marty: So, what do we do?
Doc: I have a plan
Cut to Biff's car. He drives along, not noticing the flying DeLorean almost right behind him. Biff has the radio on.
Radio Announcer: (v.o) Repeating tonight's earlier weather bulletin, a severe thunderstorm is heading for Hill Valley.
The DeLorean - Marty opens the door and puts his left foot on the hoverboard, through the strap. He then takes off and grabs onto the back of Biff's car.
Radio Announcer: (v.o) Serving Hill Valley and all of Hill County, you're tuned to KKHV, the voice of Hill Valley.
Biff adjusts the tuning a bit. Marty looks at Doc and gives him a thumbs-up. Doc gives one back and then the DeLorean flies off. Cut back to Biff's car.
Radio Announcer: (v.o) Turning to the community calendar, the Hill Valley Women's Club Bake Sale will be held tomorrow afternoon from 2-5 at the Community Center on Horace Road.
Marty appears in the background. During the following Marty moves around the car until he's hanging onto the side of it.
Radio Announcer: (v.o) For you sports fans out there, there was a lot of action today in college football. Here's what happened in the top 10. UCLA narrowly defeated Washington 19-17.
Marty sees the Sports Almanac in the back of the car.
Radio Announcer: (v.o) Michigan State crushed Minnesota 42-14.
Biff grabs the almanac just as Marty tries to grab it.
Radio Announcer: (v.o) Ohio State beat Iowa 20-10. Michigan blanked Indiana 30-0.
Biff is checking these results in the almanac. He's amazed - they're right!
Marty: (muttering) Shit.
