If you dent this car, I'll kill you.
BIFF: This cost me $300!
OLD BIFF: Would you shut up about the car?
- How do you know where I live?
- Let's just say we're related, Biff.
That being the case, I got a present for you.
Something that'll make you rich.
- You want to be rich, don't you?
- Yeah. Sure. Right. That's rich.
You're going to make me rich?
You see this book?
This book tells the future.
Tells the results of every major sports event
till the end of this century.
Football, baseball, horseraces, boxing.
The information in here is worth millions,
and I'm giving it to you.
That's very nice. Thank you very much.
Now, why don't you make like a tree
and get out of here?
It's leave, you idiot. Make like a tree and leave.
You sound like a fool when you say it wrong.
All right, leave. And take your book with you.
Don't you get it?
You could make a fortune with this book.
Let me show you.
[Static coming from radio]
RADIO: UCLA trails 17-16.
It's 4th and 11
with only 18 seconds left of this game.
I'd say it's all over for UCLA.
Bet you a million bucks UCLA wins it 19-17.
- What are you, deaf? It's over. You lost.
- Yeah?
Here comes Decker with the kick.
It's up and looks good.
Ball's in the clear.
Field goal! UCLA wins 19-17.
Listen to that Coliseum crowd go wild.
Jim Decker...
All right. What's the gag?
How did you know what the score would be?
OLD BIFF: I told you, it's in this book.
All you got to do is bet on the winner,
and you'll never lose.
All right. I'll take a look at it.
OLD BIFF: You damn fool!
Never leave this book laying around.
Don't you have a safe?
No, you don't have a safe.
Get a safe. Keep it locked up.
Until then, keep it on you.
BIFF: What are you doing?
OLD BIFF: Don't tell anybody, either.
OLD BIFF: There's one more thing.
One day, a kid or a crazy old man...
... who claims to be a scientist
is going to come around asking...
I'm trapped. Doc.
MARTY: Doc, come in.
- What's the report?
- Biff's gone.
MARTY: He's got the book.
I'm locked in Biff's garage.
Get me the hell out of here.
I'm at 1809 Mason Street.
I can't take the DeLorean.
Don't worry. Somehow I'll get there.
Doc, wait a minute. Doc. Doc.
Perfect.
GRANDMA: Biff! Where are you going now?
BIFF: I told you, Grandma,
I'm going to the dance.
GRANDMA: When you coming home?
MARTY: The dance.
BIFF: I'll get home when I get home.
GRANDMA: Don't forget to turn out
the garage light.
[Tires screeching]
[Bicycle bell ringing]
DOC: Marty. Marty!
Marty.
Marty, Marty. Damn!
Where is that kid?
[Perry Como's Papa Loves Mambo
playing on radio]
MARTY: Doc. Doc, come in.
Come in, Doc.
Marty! Come in.
Doc.
[Static interference]
Marty.
My...
Great Scott.
DOC: My God.
MARTY: Doc, Doc, come in.
Marty, what happened?
You weren't at Biff's house.
MARTY: I'm in Biff's car, heading for
the Enchantment Under The Sea dance.
We may have to abort this entire plan.
It's getting much too dangerous.
MARTY: The book's on his dashboard.
I'll grab it when we arrive.
You must be careful
not to run into your other self.
- My other self?
- Yes.
Remember your mother is
at that exact same dance with you.
MARTY: Right. This could get heavy, Doc.
DOC: Heavy, heavy.
Whatever happens,
don't let your other self see you!
DOC: The consequences could be disastrous.
OTHER DOC: Excuse me, sir.
Yes, you with the hat.
- Who, me?
- Yes.
Be a pal and hand me a five-eighths inch wrench
from the toolbox.
Five-eighths?
Don't you mean three-quarters?
Why, you're right.
I presume you're conducting
some sort of weather experiment.
That's right. How did you know that?
I happen to have had a little experience
in this area.
I'm hoping to see some lightning tonight...
...although the weatherman says
there's no chance of rain.
There's going to be
