Whatever happens,
don't let your other self see you!
The consequences could be disastrous.
OTHER  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 plenty of rain.
Wind, thunder, lightning.
- It's going to be one hell of a storm.
- Thanks. Nice talking to you.
Maybe we'll bump into each other again
in the future.
Or in the past.
Doc, Doc! Come in!
Where's that punk Calvin Klein, anyway?
I don't know. I ain't his secretary.
Well, find him.
He caused me $300 damage.
I owe him a knuckle sandwich. Get going!
Aren't you coming?
I'm reading.
Well, well, Mr. Tannen.
How nice to see you here.
- Why, Mr. Strickland, nice to see you, sir.
- Is that liquor I smell, Tannen?
I wouldn't know.
I don't know what it smells like
because I'm too young to drink it.
I see.
What have we here?
Sports stats,
interesting subject. Homework, Tannen?
No, it ain't homework,
because, I ain't at home.
You got a real attitude problem, you know?
One day I'll have you where I want you,
in detention.
Slacker!
Jesus, you smoke, too?
Marty,
you sound just like my mother.
Yeah, right.
When I have kids,
I'll let them do anything they want.
Anything at all.
- I'd like to have that in writing.
- Yeah, me, too.
Marty, why are you so nervous?
Yes!
No!
"Oh LбLб"?
"Oh LбLб"?
"Oh LбLб"?
Doc! Doc!
Hey, you.
Doc, come in!
Marty, what's up?
Doc! I'm in trouble. I blew it.
Where's the book?
Biff must have it.
I've only got the cover.
Where's Biff?
You're asking for it.
I don't know.
Any idea?
No! He could be anywhere by now.
The entire future depends on you
getting that book!
I know. I just don't...
Stop it!
Stop it, Biff. You'll break his arm. Stop itl
Of course!
I gotta go. I got one chance!
My old man is about to deck Biff!
Yes!
Talk about dйjб vu.
Are you okay?
Okay, everybody, let's back up.
Everybody just back up.
Give him a little bit of room.
It's okay. I know CPR.
I know CPR.
- What's CPR?
- You!
- He's fine.
- Did you just take his wallet?
He took that guy's wallet.
Doc, success. I got it.
Thank goodness.
Great, Marty.
As soon as I reload the fusion generator
we'll meet on the roof of the school gym.
On the roof. 10-4.
It's him!
He's in disguise.
Guys, what's that?
Come on! Let's get him!
Damn!
All right! Let's do another.
Where did he go?
He just came in here!
- Look! How did he get on stage?
- When he's through, we'll nail him.
How did he change his clothes so fast?
OTHER  It's an oldie
where I come from.
All right, guys, blues riff in B.
Watch me for the changes,
and try and keep up, okay?
Doc, come inl
Come in.
Listen, Biff's guys chased me into the gym.
They're going to jump "me."
Get out of there!
No, not me. The other me.
The one on stage playing Johnny B. Goode.
He could miss his opportunity to return!
We'll have a major paradox!
Wait. A paradox?
One of those things
that could destroy the universe?
You have to stop those guys
without being seen by your other self.
10-4.
What the hell?
- Where is he?
- Who?
- Calvin Klein.
- Who?
- With the hat, where is he?
- He went that way.
W I think he took your wallet.
I think he took his wallet.
I guess you guys aren't ready for that yet...
...but your kids are going to love it.
Doc, success. Everything's cool.
Great. I'll be landing
at the roof in one minute.
I'll be there.
Lorraine.
Marty, that was very interesting music.
I hope you don't mind.
George asked to take me home.
OTHER  Yeah. Great. Great.
I had a feeling about you two.
I had a feeling, too.
