Marty McFly: Doc, we better back up. We don't have enough road to get up to 88.
Dr. Emmett Brown: Roads? Where we're going, we don't need roads.
Doc Brown: Now, if my calculations are correct, when this baby hits eighty-eight miles per hour, you're gonna see some serious shit.
Marty: Doc look, all we need is a little plutonium!
Doc: Oh! I'm sure that in 1985, plutonium is available at every corner drug store, but in 1955 it's a little hard to come by. Marty, I'm sorry, but I'm afraid you're stuck here.
Doc: The only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning.
Doc: A bolt of lightning! Unfortunately, you never know when or where it's ever going to strike!
[Marty holds out the "Save the Clock Tower" flyer]
Marty: We do now.
Doc: Next Saturday night, we're sending you Back to the Future!
Marty: That's right, Doc. November 12, 1955.
Doc: Unbelievable, that old Biff could have chosen that particular date. It could mean that that point in time inherently contains some sort of cosmic significance. Almost as if it were the junction point for the entire space-time continuum. On the other hand, it could just be an amazing coincidence.
Marty: You're not going to believe this. We have to go back to 1955.
Doc: I don't believe it!
Doc: The time-traveling is just too dangerous. Better that I devote myself to study the other great mystery of the universe...women!
Doc: Marty! What in the name of Sir Isaac H. Newton happened here?
Marty: I don't get it, Doc. I mean, how can all this be happening? It's like we're in Hell or something.
Doc: No, it's Hill Valley. Although I can't imagine Hell being much worse!
Doc: Marty, you're not thinking fourth-dimensionally!
Marty: Yeah, right, I have a real problem with that.
Doc: This'll shoot the fleas off a dog's back at 500 yards, Tannen! And it's pointed straight at your head!
Jennifer: Excuse me, Doc Brown. I brought this message back from the future and, well, now it's erased.
Doc: Of course it's erased.
Jennifer: But what does that mean?
Doc: It means your futures haven't been written yet. No one's has. So make it a good one, the both of you.
Engineer: Is this a holdup?
Doc: It's a science experiment!
Doc: Clara was one in a million. One in a billion. One in a googolplex!
Mr. Goodman: The piranha hunt in packs. The first bite draws blood, blood draws the pack.
