* When Biff and his gang are about to slam into the manure truck, they all shout in unison, '''''"[[VisualPun SHIIIIIIIIIIIIIT!!!]]"'''''

* The opening scene. Marty uses a [[KeyUnderTheDoormat key under Doc's doormat]] to get into his lab (muttering "''Aw, God!'' Oh, Jesus... That is ''disgusting'', what the hell is it with him..." when he notices the bowl full of [[{{Squick}} spoiled dog food]]), and proceeds to fiddle with different knobs and switches to activate a [[UpToEleven ridiculously gigantic amplifier]] at full volume. [[WhatAnIdiot Which he is standing right in front of.]] He gets into position, readying his guitar pick...[[GaleForceSound and is promptly blown across the room by the noise]], destroying the amp in process and crashing into a bookcase. [[GlassesPull "Rock 'n' roll"]] indeed.

-->'''Marty:''' Yeah... I'll keep that in mind...

* When Biff and his gang are about to slam into the manure truck, they all shout in unison, '''''"[[VisualPun SHIIIIIIIIIIIIT!!]]"'''''

* "So why don't you make like a tree... and [[{{Metaphorgotten}} get out]][[{{Malaproper}} ta here]]?". One of Biff's goons clearly rolls his eyes at this.

* Tom Wilson (the actor who played Biff) wrote [[https://www.youtube.com/watch?v=iwY5o2fsG7Y this song]] to answer a lot of questions he gets about the film.

* "I'm gonna catch you a break today. So why don't you make like a tree... and [[{{Metaphorgotten}} get out]][[{{Malaproper}} ta here]]?". One of Biff's goons clearly rolls his eyes at this.

** "I'm your density." Just the way George awkwardly approaches Lorraine, holding his notebook out halfway over the table, and then Lorraine and her friends staring blankly at him as he breathes, "My density... has popped me to you." And she responds with a FlatWhat

* "If my calculations are correct, when this baby hits 88 miles an hour... [[SophisticatedAsHell you're gonna see some serious shit]]."

* "Why don't you make like a tree... and [[{{Metaphorgotten}} get outta here]]". One of Biff's goons clearly rolls his eyes at this.

* "Why don't you make like a tree... and [[{{Metaphorgotten}} get outta here]]."

'''Doc:''' ''Ronald Reagan''? The ''actor''? Then who's Vice President? Creator/JerryLewis?! I suppose Jane Wyman is the First Lady! And Jack Benny is Secretary of the Treasury!

** Made even funnier when Doc [[NowYouTellMe calls afterwards to warn Marty not to use the amplifier]].

* Tom Wilson (the actor who played Biff) wrote [[https://www.youtube.com/watch?v=WmjYimspW-4 this song]] to answer a lot of questions he gets about the film.

* From a [[http://youtu.be/JVf6aYCGPYI?t=10s deleted scene]], after Marty looks at the newspaper confirming that he's in 1955, an elderly woman bumps into him. What does Marty do? He asks her to [[PinchMe pinch him]] to confirm that this is real. [[EpicFail He gets a slap instead.]]

* Marty's horror when Lorraine dismisses his criticism of her smoking by saying he sounds like her mother.

* From the first episode of the [[WesternAnimation/BackToTheFuture animated series]]:
--> '''Doc''': Always take the aluminium foil off your burrito before you put it in the microwave!
* "[[Recap/BackToTheFutureTheAnimatedSeriesS1E11GoneFishin Gone Fishin']]": The entire sequence after Marty, the boys, and Emmett examine the materials for the final stunt (going over Upper Yosemite Falls in a barrel). Given the amount of danger involved, Verne asks what idiot would come up with this kind of feat for a four-year-old. Cue the arrival of D.W. Tannen, prompting Marty to comment that he expected this. When Emmett expresses his doubts, Tannen tells him that the stunt is "movie magic" and that he'll be replaced by a dummy before the barrel actually goes over the falls. Without missing a beat, Marty asks if that means Tannen is doing it.

-->'''Marty:''' You know, [his EngineeredHeroics plan] is the kind of thing that could screw me up permanently. What if I go back to the future and I end up bein'... ''[[ValuesDissonance gay?]]''\\

** Marty initially seems dumbfounded about Doc making a time machine, but his last line almost makes him [[ComicallyMissingThePoint sound more concerned about what kind of car it is]].
** And then it sounds like he's about to ask if he can borrow it so he can go to the lake with Jennifer.

** A notable example is when the flaming wind-up car runs off the table and sets fire to some old rags. Even though his eyes are covered by his goggles, [[http://img2.wikia.nocookie.net/__cb20080320220833/bttf/images/7/73/Docgasp.jpg his reaction]] is priceless. Merely typing "huh!" doesn't even begin to cover the emotion Lloyd conveys in that second.
** It's more like "YHHHUUUAH!"

* After the manure truck incident, Doc and Marty work out how they're going to get George and Lorraine together, as well as their plan for how to get the lightning bolt to power the flux capacitor...and then Lorraine turns up at Doc's house, having followed Marty here, to tell Marty that a real man stands up for the woman he loves.[[note]]Marty had just punched out Biff at Lou's Cafe.[[/note]] As she's saying this, Doc leans forward onto the covered [=DeLorean=] in a HeadDesk.
** From the look on Doc's face, the whole time he is clearly thinking "this is bad, this is really bad, this is really, ''really'' bad".

'''Doc:''' ''[baffled]'' Weight has nothing to do with it!\\

** In a magazine interview from 2015, Thompson actually pointed out that was her favorite scene to shoot, because everyone was in on it except Fox, and she comments that he was so tired from filming the movie AND ''Series/FamilyTies'' at the same time that he probably wanted to just drink it.

-->'''George:''' WHAT?

--->'''[=LatinoThug=]!Marty:''' Eh, ''puto''! There she is, mang, there's the bitch! ''[looks through the window]'' Cheatin', mang... SUNUVA BITCH, SHE CHEATIN', MANG! ''[bangs on door]'' ''EH, BITCH!!'' No homeboy for her tonight, mang.

-->'''Old Man Peabody:''' My pine! Why you... ''[shoots at the [=DeLorean=], misses and hits the mailbox]'' '''YOU SPACE BASTARD! ''YOU KILLED MY PIIIIINNNEEE!!'''''
** Even funnier when you look at the sign for the Twin Pines Mall (where Peabody's farm once stood) at the end of the movie; ''[[BrickJoke it is now called Lone Pine Mall!]]''
** And before that:

'''Old Man Peabody:''' ''[fires a shotgun]'' Take that, you mutatin' son of a bitch!
** And before ''that'':
--->'''Marty:''' Hello? Ah...excuse me? ''[points behind him awkwardly]'' Sorry about your barn. ''[BANG from shotgun, Marty stumbles back and trips]''

* The part when Marty tries to get directions from the guy in the cafe:

** And if you look closely when that scene first starts, you'll see that the suction-cup thing Doc puts on Marty's forehead was originally on the top of Copernicus's head. Yes, before Marty showed up, Doc was trying to read the mind of his DOG!

* The "Who's president in 1985?" exchange is just outright hilarious because of Doc's hamminess.

** [[https://www.youtube.com/watch?v=_-MDtPK0hbY Another deleted scene]] shows Marty peeking into a classroom window and seeing Lorraine cheating on a test. She's then seen telling her friends that she got an F anyways.

** Doc's face through that scene is pure hilarity. You just know the old guy is thinking "this is bad, this is really bad, this is really, ''really'' bad".

* Marty's confrontation with Biff when he shows up to toss George up. The way he towers over Marty who has just [[ContrivedClumsiness casually tripped him up]] in the cafe, the camera catching a glimpse of Marty's [[OhCrap classically scared face]] (just watch his eyes) as it happens (the fact that he's barely able to see over Biff's shoulders shows it is hilarious). Marty then quickly pulls the oldest trick in the book by [[LookBehindYou pointing at something behind Biff]], punching him in the face when he's distracted, and then taking off. Doubles as SugarWiki/MomentOfAwesome.

'''Marty:''' ''[just as baffled as Doc]'' What?\\
