Quote from : Back to the Future Part III Movie

Marty McFly: [running into the Saloon] Doc. What are you doin'?
Doc: I've lost her, Marty. There's nothing left for me here.
Marty McFly: Yeah, that's why you gotta come back with me.
Doc: Where?
Marty McFly: Back to the future.
Doc: [Nods his head] Right. Let's get going.
[puts down his glass of whiskey]
Marty McFly: [muffled] Great.
Doc: Gentlemen, excuse me. But, my friend and I have to catch a train.
Saloon Old-Timer #1: Cheers to ya, blacksmith.
Saloon Old Timer #3: And to the future.
Saloon Old-Timer #2: Amen.
Doc: [picks up his glass of whiskey] Amen.
Bartender: Emmett, no!
[Doc throws back the whiskey and turns and passes out, tipping over a table in the process]
