The other two old timers laugh hysterically. Meanwhile in town Marty gets off his horse and runs into the blacksmith shop.
Marty: Doc! Doc!
Marty sees Doc isn't there and leaves, spotting the saloon. We cut back to the saloon.
Old Timer 1: How much has he had?
Chester: None. That's his first one and he hasn't touched it, yet. He just likes to hold it.
The Old Timers laugh as Marty runs in and spots Doc.
Marty: Doc! Doc! What're you doing'?
Doc: I lost her, Marty. There's nothing left for me here.
Marty: All right, so that's why you've gotta come back with me.
Doc: Where?
Marty: Back to the future!
Doc springs to life. He realises what he has to do. He puts his glass down.
Doc: Right. Let's get going!
Marty: Great!
Doc: Gentlemen, excuse me, but my friend and I have to catch a train.
Old Timer 1: Here's to ya, blacksmith.
Old Timer 2: And to the future!
Old Timer 3: Amen.
The Old Timers raise their glasses to Doc.
Doc: Amen.
Doc raises his glass to them. Chester realises what is about to happen.
Chester: Emmett, no!!
Too late. Doc swallows the whiskey. Marty and Chester watch in horror as Doc steps forward, and faints onto the Old Timer's table.
Marty: Doc! Doc! Doc! C'mon, Doc, wake up, wake up, Doc. (to Chester) How many did he have?
Chester: Just one.
Marty can't believe it!
Marty: Just one?! (to Doc) C'mon, Doc.
Chester: There's a fella that can't hold his liquor.
Marty: Gimme some coffee... black.
Chester: (calling to his assistant) Joey, coffee!
Marty looks out the window. The clock is outside. It's 7.45. 15 minutes to go. We cut to a road, where Buford and his gang ride towards Hill Valley. We then cut to the train station. Clara is at the ticket office, speaking to the CLERK.
Clerk: Ma'am.
Clara: How far does the 8 o'clock train go?
Clerk: San Francisco's the end of the line.
Clara: I'll take a one way ticket.
Back in the saloon, Marty feeds Doc coffee, but it isn't working.
Chester: You want to sober him up in a hurry, son, you're gonna have to use something a lot stronger than coffee.
Marty: Yeah, what do you suggest?
Chester smiles as he calls to JOEY, his assistant.
Chester: Joey. Let's make some wake up juice.
Joey and Chester set out a variety of ingredients as they make the wake-up juice.
Chester: In about 10 minutes, he's gonna be as sober as a priest on Sunday.
Marty: 10 minutes?
Marty again looks at the clock. It is now 7.50.
Marty: Why do we have to cut these things so damn close?
Chester walks over with a funnel, clothes peg and the glass of liquid.
Chester: Here, stick this clothespin on his nose, and when he opens up his mouth, go ahead and pour it on down his throat. Oh, and stand back.
Marty does as Chester says, but nothing happens. Suddenly Doc stands up, opening his eyes and jumps up!
Doc: Wah! Hot! Hot!
