Marty McFly, Jr.: Hey, Gram, could you just stuff the whole thing in my mouth?
Middle-Aged Marty: Don't you be a smart-ass!
'Ronald Reagan' Video Waiter: Welcome to the Cafe 80's, where it's always morning in America, even in the afternoon. Our special today is mesquite-grilled sushi...
'Ayatollah Khomeini' Video Waiter: [interrupts] You must have the hostage special!
Marty McFly: Hey, hey, hey, hey, guys, hey, hey! All I want is a Pepsi.
Doc: Sometime today, old Biff will show up to give young Biff the Almanac. Above all, you must not interfere with that event. We must let Old Biff believe he succeeded, so that he'll leave 1955 and bring the DeLorean back to the future.
Marty McFly: Right.
Doc: Once Old Biff is gone, grab the Almanac anyway that you can. Remember, both of our futures depend on this.
Marty McFly: You don't have to remind me of that, Doc.
Young Doc: Nice talking to you. Maybe we can bump into each other sometime again in the future.
Older Doc: Or in the past.
Doc: Time circuits on.
Marty McFly: Time circuits on? What do you mean "Time Curcuits on"? Doc, we're not going back now!
Marty McFly: Doc, What about Jennifer? What about Einstein? We can't just leave them here.
Doc: Don't worry, Marty. Assuming we succeed in our mission, this alternate 1985 will be changed back into the real 1985, instantaneously transforming around Jennifer and Einie. Jennifer and Einie will be fine, and they'll have absolutely no memory of this horrible place.
Marty McFly: Doc... what if we don't succeed?
Doc: We must succeed.
Marty McFly: Are you two related?
Biff Tannen: Hello? Hello? Anybody home? What do you think? Griff just called me Grandpa for his health?
Western Union Man: Kid, you all right? You need any help?
Marty McFly: There's only one man who can help me.
Marty McFly: The answer's no, Griff.
Griff Tannen: No?
Marty McFly: Yeah, what are you deaf and stupid? I said "NO!"
Griff Tannen: What's wrong, McFly. 'You chicken?
Old Biff: Hello? Hello? Anybody home? Huh? Think, McFly! Think! Your old man, Mr. Loser?
Marty McFly: What?
Old Biff: That's right. Loser with a capital "L".
Marty McFly: Look, I happen to know that George McFly is not a loser...
Old Biff: [interrupts] I'm not talkin' about George McFly. I'm talkin' about his kid! Your old man, Marty McFly Sr.? The man who took his life and flushed it completely down the toilet.
Marty McFly: I did? I- I mean he did?
Old Biff: Tough break, kid. Must be rough bein' named after a complete butthead.
Marty McFly: What's that supposed to mean?
Old Lorraine: Aren't you and Jennifer getting along?
Middle-Aged Marty: Oh, yeah, Mom. We're like a couple o' teenagers, ya know?
Hey kid, say hi to your grandma for me.Biff Tannen
