Young Doc: No wonder this circuit failed. It says "Made in Japan".

Young Doc: Unbelievable.

Buford "Mad Dog" Tannen: Then let's settle it, right now!
Buford's Gang Member #1: Uh, not now, Buford. Marshal's got our guns.
Buford "Mad Dog" Tannen: Like I said, we'll finish this tomorrow.
Buford's Gang Member #2: Tomorrow, we're robbing the Pine City Stage.
Buford "Mad Dog" Tannen: What about Monday? Are we doing anything Monday?
Buford's Gang Member #1: Uh, no, Monday would be fine. You can kill him on Monday.
Buford "Mad Dog" Tannen: I'll be back this way on Monday! We'll settle this then... right there... out in the street... in front of the Palace Saloon!
Marty McFly: Yeah, like when? High noon?
Buford "Mad Dog" Tannen: Noon? I do my killin' before breakfast! Seven o'clock!
Marty McFly: Eight o'clock. I do my killing after breakfast!
Marty, we all have to make decisions that affect the course of our lives. You've got to do what you've got to do. And I've got to do what I've got to do.Doc
Marty, you can't go losing your judgment every time someone calls you a name. It's exactly what causes you to get into that accident in the future.Doc
We shall proceed as planned, and as soon as we return to 1985, we shall destroy this infernal machine. Traveling through time has become much too painful.Doc
Doc: Marty, I gave you explicit instructions not to come here but to go directly back to 1985.
Marty McFly: I know, Doc.
Doc: But it's good to see you, Marty.
Clara was one in a million. One in a billion. One in a googolplex!Doc
Jennifer Parker: Dr. Brown, I brought this note back from the future and now it's erased.
Doc: Of course it's erased.
Jennifer Parker: But what does that mean?
Doc: It means your future hasn't been written yet. No one's has. Your future is whatever you make it. So make it a good one, both of you.
Marty McFly: We will, Doc.
Engineer: Is this a holdup?
Doc: It's a science experiment!
Doc: Marty, you're not thinking fourth dimensionally!
Marty McFly: Yeah, I know, I got a real problem with that.
Marty McFly: Listen, you got a back door to this place?
Bartender: Yeah, it's in the back.
