History Funny / BACKTOTHEFUTURE

* [[https://www.youtube.com/watch?v=O_vb22cwHag This crossover parody]] between the first ''Film/BackToTheFuture'' movie and ''Film/XMenDaysOfFuturePast'' (which is also a TimeTravel film) is pure comedic gold.

[[folder:Part I]]
* 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 ridiculously gigantic amplifier at full volume. 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.
** Made even funnier when Doc [[NowYouTellMe calls afterwards to warn Marty not to use the amplifier because there's a slight possibility of overload]].
--->'''Marty:''' Yeah... I'll keep that in mind...
** The news report at the beginning about the missing plutonium, before we see a ground-level shot as Marty walks in and rolls his skateboard across the floor. Three guesses to what's hiding from Marty's view that it hits, and two of them are wrong.
* [[http://youtu.be/dR_wNXvcZ9g?t=34s A blooper version]] of Marty heading to school at the beginning. He kicks Doc's gate open...only it won't shut again, so he just throws his skateboard at it and runs away. Eagle-eyed viewers can see Creator/MichaelJFox starting to laugh as he leaves the camera shot.
* [[Music/HueyLewisAndTheNews Huey Lewis]] cameos as an audition judge who tells Marty's band, The Pinheads, that they're "just too darn loud" when they play [[HypocriticalHumor Lewis' own song "The Power of Love."]]
* Marty and Jennifer [[AlmostKiss having their kiss interrupted]] by the [[MomentKiller "Save the clock tower!" lady]]. Summarized best in [[https://31.media.tumblr.com/7bead3419527516bb8c6d5cc341ef732/tumblr_inline_mz7fmtlcK01qzz4ul.gif this gif]]; just check out the look of exasperation on Marty's face.
* Lorraine's execution around the dinner table of her reminiscing of how she met George. All of it. The fact that they met in such ridiculous circumstances makes it all the more funny what with how lovesick she sounds.
-->'''Linda:''' ''[aghast]'' That was so ''stupid!'' Grandpa hit him with the car!\\
'''Lorraine:''' ''[firmly]'' It was ''meant to be''.
* "[[IfMyCalculationsAreCorrect If my calculations are correct]], when this baby hits 88 miles an hour... [[SophisticatedAsHell you're gonna see some serious shit]]."
** And Marty (understandably) freaking out at the car vanishing is hilarious to watch:
--->'''Marty:''' Jesus Christ..! Jesus ''Christ'', Doc, you disintegrated Einstein!\\
'''Doc:''' Calm down, Marty. I didn't disintegrate anything. The molecular structure of both Einstein and the car are completely intact!\\
'''Marty:''' ...THEN WHERE THE HELL ''ARE'' THEY?!\\
'''Doc:''' The appropriate question is, "''When'' the hell are they?!" You see, Einstein has just become the world's first time traveler! I sent him into the ''future''! One minute into the future, to be exact! And at precisely 1:21 a.m. and zero seconds, we shall catch up with him and the time machine.\\
'''Marty:''' ''[{{beat}}]''...Wait a minute. Wait a minute, Doc. ''Ah''...Are you telling me you built a ''time machine''...out of a ''DELOREAN''?\\
'''Doc:''' The way I see it, if you're gonna build a time machine into a car, why not do it with some ''[[RuleOfCool style]]''?
** Marty initially seems dumbfounded about Doc making a time machine, but [[BaitAndSwitchComment his last line]] almost makes him [[ComicallyMissingThePoint sound more concerned about]] [[TheAllegedCar what kind of car it is]]. ''Then'' it sounds like he's about to ask if he can borrow it so he can go to the lake with Jennifer.
** LOOK at Marty's face when Doc is going over "when the hell" Einstein and the [=DeLorean=] have gone to. His amazingly confused/"what the flying fuck just happened?!?" expression is ''perfect''.
** Before that, there's a great bit where Doc is revving up the [=DeLorean=], which is pointing right at the two of them. Marty starts to edge out of the way until Doc notices him and gives him a silent, confused look, as if he can't imagine why Marty would try to move. Marty sheepishly gets back into position.
*** And then, as the [=DeLorean=] speeds towards them, Marty breaks to run to the side, and Doc just grabs him and yanks him back, excitedly saying "Watch this, watch this!" Especially funny (or terrifying) is that ''Doc'' seems almost more surprised than Marty that it actually ''worked.'' Given what we find out about Doc's scientific prowess in 1955...what are the odds he was just working on an incredibly-elaborate way to run himself and Marty over?
** Blink and you will miss it: The [=DeLorean=] is equipped with Good''year'' tires.
* Two words: "[[https://www.youtube.com/watch?v=b68FvBphfaQ HOLY SHIT!]]"
* When Marty leaves the Peabodys' farm, he accidentally runs over one of the two twin baby pine trees.
-->'''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 Marty runs back to the mall at the end of the movie, it is now called [[BrickJoke Lone Pine Mall.]]
** Marty stumbles out of the car after accidentally scaring the Peabodys into retreating to the house.
--->'''Marty:''' Hello? Ah...excuse me? ''[points behind him awkwardly]'' Sorry about your barn. ''[Peabody begins shooting at him with a shotgun. Marty stumbles back and trips]''\\
'''Sherman:''' It's already mutated into human form, shoot it!\\
'''Old Man Peabody:''' ''[fires shotgun]'' Take that, you mutatin' son of a bitch!

** [[RuleOfThree And before THAT]], the time jump from 1985 to 1955. Crashing into a scarecrow? Funny. Marty screaming at the scarecrow, noticing he's about to crash into a barn, then starting screaming AGAIN? ''Hysterical''.
*** Not to mention Marty's radiation mask flipping down over his head, [[Franchise/ToyStory Buzz Lightyear]] style, before he crashes.
* 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 [[DreamRealityCheck pinch him]] to confirm that this is real. [[EpicFail He gets a slap instead.]]
-->'''Marty:''' ''[holding his cheek in pain]'' Yeah, that'll do...
* The whole RunningGag involving Marty's vest and everyone mistaking it for a life jacket.
-->'''Skinhead:''' Hey, Biff, get a load of this guy's life preserver. The dork thinks he's gonna drown!
* Marty's failed attempt to get directions to Lou:
-->'''Lou:''' ''[interrupting]'' Are you gonna order something, kid?!\\
'''Marty:''' Uh, yeah. Give me a Tab[[note]]The pre-1981 version of Diet Coke (though Coca-Cola continued to make Tab as a saccharin alternate to the aspartame-based (and more popular by 1985) Diet Coke).[[/note]].\\
'''Lou:''' Tab? I can't give you a tab unless you order something.\\
'''Marty:''' Okay, give me a Pepsi Free[[note]]The 1980s version of Caffeine-Free Pepsi[[/note]].\\
'''Lou:''' You want a Pepsi, pal, you gotta pay for it!
** Marty eventually gets Lou to give him a sugar-free coffee. As Lou sets the coffee down, the camera finally shows that Marty is sitting next to George...which Marty doesn't realize until a moment later when Biff and his gang stop by to harass George. After Biff leaves, we get a hilarious shot of George staring straight ahead, trying his hardest to ignore Marty as he slowly leans farther and farther forward to stare at George's face with a "holy shit" expression. Not only that, but the shot frames it from the side, where Marty's aforementioned expression is made all the more funny slowly appearing from behind George's straight face.
--->'''George:''' WHAT?
*** Further more on the coffee bit, Marty puts a handful of change on the bar that's no doubt the exact change (or close to it) for a cup in 1985. Lou leaves some coins on the bar, and gives Marty more change, prompting a confused look.
** The immediate reaction of Marty replying with "You're George [=McFly=]!" when George finally cracks. Marty is only able to say that because he'd sound crazy otherwise, and the way it sounds makes it so ridiculous because he's already so shocked. What really nails it is George's "Yeah, who are you?" because he has no idea what he's making such a big deal about.
** At that point, Goldie Wilson, the busboy and future mayor of Hill Valley, pops in to chide George for letting Biff walk all over him. Marty can't help but inadvertently blurt out to Goldie that he's going to become Mayor in 30 years. This ends up giving Goldie the idea to run for Mayor, to which Lou scoffs "[[ItWillNeverCatchOn A colored mayor? That'll be the day]]."
* Marty first meets his mother as an attractive teenage girl...and immediately experiences a mini-Oedipal breakdown, not helped by the fact that she's obviously into him:
-->'''Marty:''' You're my muhh... you're my ''muhh''...\\
'''1955 Lorraine:''' My name is Lorraine. Lorraine Baines.\\
'''Marty:''' ''[with an audible squeak]'' Yeah!... but you're ''hooo''[[note]] hot[[/note]] ...you're so ''hooo'''aah''''', you're so... ''thin!''
** In the process of this, Marty backs off as his mother, completely unaware, makes her advances, before she gets so close that he ends up falling off the bed. Then, Marty's jeans are thrown back at him whereby he falls over trying to put them on.
*** If you listen really carefully when Marty is pulling his jeans on, just as he tips forwards but just before he hits the ground, you can hear him hiss "Shit!"
*** [[FunnyBackgroundEvent And if you look carefully in the mirror behind Marty here]], you can see Lorraine leaving the room, [[CovertPervert who makes a ":D" face as she briefly looks at Marty in his undies]].
** Lorraine's never seen purple underwear before. What's even more creepy yet still funny is the fact that Lorraine reads his name as "Calvin Klein" because she looked at his underwear.
*** This also leaves the viewer wondering ''why the hell Marty wasn't wearing his pants in the first place''. Knowing that maybe SHE took them off makes the situation even more hilariously creepy.
* At dinner with Lorraine's family, Marty finally meets his Uncle Joey, the future jailbird, who is still a baby at this point in time:
-->'''Marty:''' So you're my uncle Joey. ''[taps the bars on the side of Joey's crib]'' Better get used to these bars, kid.
** And the follow-up, where Joey's mother says, "[[EarlyPersonalitySigns He cries whenever we try to take him out, so we just leave him in there all the time]]." Not to mention that he's got a ''striped shirt''.
* Marty asking Lorraine's parents where Doc's house is. Since this is 1955, they haven't heard of President Kennedy yet.
** When Marty leaves, Lorraine's parents comment on his behavior. Irony abounds, and all the while Lorraine is staring lovingly after him.
--->'''Stella Baines:''' He's a very strange young man.\\
'''Sam Baines:''' He's an idiot. Comes from upbringing. His parents are probably idiots too. Lorraine, [[DramaticIrony if you ever have a kid like that, I'll disown you]].
** A shot under the dinner table shows Lorraine caressing Marty's leg. His barely controlled discomfort changes when he abruptly stands up as she gropes him. And Lorraine's rosy gaze in Marty's direction at the same time. His uncomfortable expression nails it.
** In fact, the entire dinner scene. Marty rescuing himself after being questioned about the plot of a brand new TV show and the concept of reruns by Lorraine's younger brother is especially notable.
** Lorraine's mother introducing Marty to her three other children... while clearly pregnant with her fifth.
* "My God! Do you know what this means? ...[[BaitAndSwitchComment It means that THIS DAMN THING DOESN'T WORK AT ALL!]]"
** Funnier thing is: It ''did'' work (somewhat), given that he pulled "[[BrickJoke Coast Guard]]" (instead of, say, Navy).
** 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 his dog's mind.
* Marty exasperatedly tugging the suction-cup thing off is pretty funny on its own.
* Doc's reaction to learning who will be President in 1985.
-->'''1955 Doc:''' Who's President of the United States in 1985?\\
'''Marty:''' UsefulNotes/RonaldReagan.\\
'''Doc:''' ''Ronald Reagan''? The ''actor''? Then who's Vice President? Creator/JerryLewis?! I suppose Creator/JaneWyman is the First Lady! And Creator/JackBenny is Secretary of the Treasury!
** When the film was being screened at the White House, Reagan ''made the projectionist stop the film and replay that scene'' because he thought the joke [[ActuallyPrettyFunny was hilarious]].
** When Marty shows Doc his "portable television studio" (camcorder), Doc seems to come around about the idea of Reagan being President:
--->'''Doc:''' No wonder your president is an actor; he needs to look good on television!
* "'''ONE POINT TWENTY-ONE GIGAWATTS!?'''"
** Marty (running after him): "What the hell is a gigawatt?!"
** Doc briefly losing it and yelling at a portrait of Tom Edison.
** "I'm sure in 1985, plutonium is available in every corner drugstore, but in 1955, it's a little hard to come by!"
*** Itself a CallBack[=/=]CallForward[=/=][[TimeTravelTenseTrouble Whatever]] to Marty berating Doc and pointing out that you can't just walk into a store and buy plutonium.
* The hilariously awkward [[RippleEffectIndicator photo]] [[http://robotcosmonaut.tumblr.com/image/102323515066 of Marty, Dave, and Linda]]. Dave's standing there wearing a WesternAnimation/MickeyMouse t-shirt and waving like a huge dork; Linda is wearing those ''ridiculous'' 80's leggings and that [[BuffySpeak big pink bow thing]]; and Marty has a half-hearted smile on his face that basically says "I really, really wish I wasn't here right now".
* The scene where Marty and Doc arrive to the school in 1955.
-->'''Marty:''' Whoa. They really cleaned this place up! Looks brand-new.[[note]]In 1985, there will be graffiti around the entrance doors[[/note]]\\
'''Doc:''' Now, remember. According to my theory, you interfered with your parents' first meeting. If they don't meet, they won't fall in love, they won't get married, and they won't have kids. That's why your older brother's disappearing from that photograph. Your sister will follow, and unless you repair the damage, you'll be next!\\
'''Marty:''' Sounds pretty heavy.\\
'''Doc:''' ''[baffled]'' Weight has nothing to do with it!
** A {{Woolseyism}} greatly improves this line in French. Marty's "heavy" is translated with an expression ("''C'est pas le pied''") which literally means "this ain't the foot", leading to the predictable retort:
-->'''Doc:''' No, the head goes first, I tell you!
** And a little later on this happens, because Marty and Doc are still having confusion about the definition of "heavy":
-->'''Marty:''' Whoa, wait a minute, Doc, are you trying to tell me that my mother...has got the ''hots for me''?\\
'''Doc:''' Precisely.\\
'''Marty:''' Whoa, this is heavy!\\
'''Doc:''' There's that word again, "heavy." Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?\\
'''Marty:''' ''[just as baffled as Doc]'' What?
* When Marty and 1955 Doc go looking for Marty's father.
-->'''Doc:''' Now, which one's your pop?\\
'''Marty:''' ''[with a grimaced expression, raises his arm, one finger pointed off-camera]'' ''That's'' him.\\
''[We see that he's pointing at Biff's gang, who are surrounding George, mercilessly kicking him as George cheerfully tries to go along with it and begs them to stop, due to a piece of paper taped to his back reading [[KickMePrank "KICK ME"]]]''\\
'''Doc:''' ''[with a somber expression on his face]'' Maybe you were adopted...\\
''[Strickland walks in as Biff's gang leave George a wreck]''\\
'''Strickland:''' [=McFly=].\\
'''Marty:''' Hey, that's Strickland! ''Je''-sus, didn't that guy ''ever'' have hair?\\
'''Strickland:''' Shape up, man! ''[tears the "Kick Me" sheet off George's back]'' You're a slacker! Do you want to be a slacker for the rest of your life?\\
'''George:''' No.\\
'''Doc:''' ''[dumbfounded]'' What did your mother ever ''see'' in that kid?\\
'''Marty:''' I don't know, Doc. I guess she felt sorry for him when her dad hit him with the car....hit ''me'' with the car. ''[rubs bump on the back of his head]''\\
'''Doc:''' That's the FlorenceNightingaleEffect. It happens in hospitals when nurses fall in love with their patients. Go to it, kid!
* A DeletedScene that's viewable in the various DVD and Blu-Ray releases:
-->'''Marty:''' You know, [his FakeDangerGambit] is the kind of thing that could screw me up permanently. What if I go back to the future and I end up bein'... ''[[HaveIMentionedIAmHeterosexualToday gay?]]''\\
'''1955 Doc:''' [[HaveAGayOldTime Why]] ''[[HaveAGayOldTime shouldn't]]'' [[HaveAGayOldTime you be happy?]]
** [[https://www.youtube.com/watch?v=_-MDtPK0hbY Another deleted scene]] (before the scene of Marty pointing George out to Doc) 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.
*** Even funnier is [[http://youtu.be/dR_wNXvcZ9g?t=47s a joke version of the scene]], in which Creator/MichaelJFox shows up in a tank top, a hairnet, and a cigarette, and acts like a stereotypical Latino thug.
---->'''[=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.
*** Made even funnier when you see that Fox is [[{{Corpsing}} visibly cracking up]] as they film it. And you can hear the crew laughing as well. But Creator/ChristopherLloyd amazingly keeps a straight face throughout.
* "So why don't you make like a tree... and [[{{Malaproper}} get outta here]]?". One of Biff's goons clearly rolls his eyes at this.
** Strickland looking ready to intervene at any moment, only to be distracted by somebody throwing a paper plane.
* Marty's first attempt at introducing George to Lorraine all but fails. George leans on the school locker casually, but Lorraine is so focused on Marty that she simply sees right through him and walks up to him instead. Leaving George awkwardly standing around before walking off.
* When figuring out how to find a social event for his parents to meet and kiss, Marty replies to Doc's question of what they like to do for fun together with a realization of "Nothing."
* Doc's [[SesquipedalianLoquaciousness penchant for using big words when smaller words could easily suffice]], such as calling the Enchantment Under the Sea Dance "A rhythmic ceremonial ritual".
* Marty's plan for getting George to ask Lorraine out:
** "My name is [[Franchise/StarWars Darth Vader]]! I am an [[Film/ETTheExtraTerrestrial extraterrestrial]] from the planet [[Franchise/StarTrek Vulcan]]!"
** Not to mention Marty using a Walkman with a Music/VanHalen tape as an AgonyBeam, and in the extended version of the scene (available on the 25th anniversary DVD) passing off a hairdryer as a brain-melting gun. And the BrickJoke that Marty knocks George out with chloroform, and in the next scene, George says he missed school because he overslept.
** The unwanted attention George draws from a passing couple as he babbles on to Marty about "Vader" threatening to melt his brain, with Marty just barely keeping him quiet about the unlikely encounter.
--->'''Marty''': Look, let's keep this brain-melting stuff to ourselves, okay?
* Marty's little quip after he tries to get George to ask Lorraine out, only for George to tell him wildly that his mind is blank.
-->'''Marty:''' Jesus, George, it's a wonder I was even born.\\
'''George:''' What?
* Marty is talking with George while trying, and failing, to twist open a glass Pepsi bottle (twist off bottle caps haven't been introduced yet). George finally gets frustrated with watching this and grabs the bottle from Marty, popping the top off with a nearby wall-mounted bottle opener and handing it back to him.
* George makes his attempt to ask Lorraine out while she's at Lou's for milkshakes. [[LactoseOverLiquor He orders one to calm his nerves first.]]
-->'''George:''' Lou, give me a milk! ''[dramatic pause]'' Chocolate!
** And the outtake where the glass slides too close to the edge of the counter, bouncing off Creator/CrispinGlover's hand and ricocheting to the floor.
** "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.
** Doubles as heartwarming when George finally gets it right and says "My destiny", only for Lorraine to respond with a soft "Oh..." and the most adorable smile ever. At least until Marty unintentionally upstages George with the skateboard chase that leads to Biff and his cronies getting humiliated.
** Also heartwarming in the IDW comic series where he repeats it to Lorraine when they're already dating in the late 50s, and they both laugh about it.
* When Biff and his gang are about to slam into the manure truck, [[MassOhCrap they all shout in unison]], "'''''[[VisualPun SHIIIIIIIIIIIIIIIIIIIIIIIIIIIIT!!!]]'''''"
** And afterwards, when Goldie Wilson reaches the car, he takes one sniff and his reaction is one of "Whoo! That is ''disgusting''!"
* Pretty much any of Doc's facial expressions throughout the trilogy. Creator/ChristopherLloyd's naturally overly-expressive eyes only make it better when he takes Doc's [[LargeHam hamminess]] up to eleven.
** A notable example is when the flaming wind-up car runs off the table and heads straight towards a bin overflowing with old rags soaked in flammable chemicals. 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!"
--->'''Marty:''' ''[deadpan]'' You're really instilling me with a lot of confidence, Doc.
** This is after he has apologized (quite seriously) for the "crudity" of the model he's built because he hasn't made it to scale or painted it. It is otherwise a large and absolutely flawless model of the area around the clock tower, and as detailed as a miniature film set.
* 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 taken 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".
* The entire sequence of Marty explaining the parking lot plan in detail, as he has to tell George that he's going to basically molest Lorraine to get her upset with him, and how visibly uncomfortable he is with the idea of it, but it gets better when George runs up gesticulating wildly with his mother's bra in one hand, saying "You mean you're gonna touch her on her-?!". And Marty interrupts George while yaning the bra out of his hands, like he wants to avoid thinking about groping his own mother where possible.
* Marty's insistence on George swearing when he opens the car door to 'save' Lorraine.
-->'''George:''' Do you really think I ought to swear?\\
'''Marty:''' Yes, definitely. Goddammit, George, swear!
** From the same scene, Marty's FreudianSlip when he's going over the plan with George. His execution in rescuing the situation by quickly replacing the word "Dad" with "[[LastSecondWordSwap Daddy-O]]" is priceless.
** And in a DeletedScene, Marty tells George [[HitMeDammit to punch him in the stomach for practice]]. George ends up giving him the most pathetic, weenie-ish little tap ever.
--->'''George:''' There! That was good! She'll believe that. I know she will, I'm fine.
*** Which, of course, makes it all the more awesome when George finally grows a pair and damn-near takes Biff's head off with one punch.
* Marty's confrontation with Biff when he shows up to toss George out. 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.
-->'''Lorraine:''' That's Calvin Klein! Oh my God, he's such a dream!
** It doesn't help Marty's case when he punches Biff, because instead of noticing George, Lorraine gets even more lovesick with Marty than before.
--->'''Lorraine:''' He's an absolute ''DREAM''.
* The HypocriticalHumor scene when Marty swipes the booze flask from Lorraine has a gag reel outtake: The prop crew secretly put real booze in it. Cue a [[EnforcedMethodActing real spit-take]] from an unsuspecting Creator/MichaelJFox. Creator/LeaThompson was in on it, judging from her amused expression and the inference that she had to take a nip from it in that scene before Michael.
** 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 actually drink it in peace.
* Marty reflexively jerking his face around to stare at Lorraine, horrified, when she dismisses his criticism of her smoking by saying he sounds like her mother (Marty's grandmother). And then Lorraine removes her jacket while Marty's head is turned around once more. When he turns back and sees his mother wearing a dress that shows off a lot of skin, he reflexively looks away with a "goddammit" look on his face.
* [[NoJustNoReaction Lorraine instantly backing off Marty after she tries to kiss him]], [[ParentalIncest instinctively feeling that it's wrong]]. "I can't explain it. It's like kissing...my brother."
** Writer/producer Bob Gale said he had a hard time writing that line, [[SureLetsGoWithThat because this situation had literally never happened before in human history]].
* [[SugarWiki/AwesomeMusic Marty's cover of "Johnny B. Goode"]]: Not the performance itself or the ''[[ThePowerOfRock EPIC]]'' guitar solo, but everybody's reactions to it. The band give him concerned looks and gradually stop playing their instruments as Marty goes into a ''full-blown heavy metal solo'' (complete with playing his guitar behind his head, kicking over the amplifier, and flailing around on the floor), and when he is done, he opens his eyes...to see the audience silently staring at him like he's a ''lunatic''. (And Strickland slowly stops covering his ears).
-->'''Marty:''' [[ALittleSomethingWeCallRockAndRoll Guess you guys aren't ready for that yet...but your kids are gonna love it.]]
** Hell, what happened in the movie was a toned ''down'' version of [[http://1-21gwts.tumblr.com/post/63150429627/film-scripts-back-to-the-future-1985-directed what was called for in the script!]]
** If you watch closely, the Starlighter's saxophone player [[FunnyBackgroundEvent is the only one who stays with Marty though the whole song]] and only starts reacting negatively [[ScrewThisImOuttaHere when Marty starts writhing on the floor]].
** And the [[ChewingTheScenery faces]] that Marty pulls when he starts to go over-the-top with his playing must be seen to be believed.
** Also, [[FunnyBackgroundEvent Marvin Berry looking at his guitar, almost thinking "What the hell did he do to this?"]]
* Marty explains that the plan to get his mother and father back together worked like a charm, even Biff was laid out in one punch. His father never stood up to him in his life. Doc contemplates this for a moment on how it might affect history, then shrugs it off. Seeing as he was so adamant about not changing history, it comes off as "Well, serves him right."
** FridgeBrilliance: You could easily point to that moment as Doc working it out that Marty just had HIS life altered via George standing up to Biff, and there were seemingly no dire consequences. So he figures "What the hell?" and eventually pieces together Marty's letter of warning.
** Also, Doc had seen how pathetic George really was, so he believes it might be for the best.
** And, of course, the picture having everyone in it that it's supposed to, ''proves'' that whatever else happens, Marty has fixed things enough so that he will exist.
* At the climax of the movie, Marty is about to set off in the [=DeLorean=] to get back to 1985. [[MyCarHatesMe The car, of course, fails on him at this moment.]] After trying and trying to get it to start up, Marty finally ''loses it'' and bangs his head against the steering wheel in a fit of rage...[[PercussiveMaintenance which starts up the engine again]]. Marty's wide eyes and {{Adorkable}} gasp at this is hilarious.
* After Marty says goodbye to George and Lorraine at the dance, he starts to leave before quickly turning around and telling them that if they ever have [[NoodleIncident a son who accidentally sets the living room rug on fire when he's eight years old]] (with hand gestures for emphasis on "accidentally"), they should go easy on him.
-->'''George:''' ''[with a confused chuckle]'' Okay.
** Right before then, as he says goodbye, he says to Lorraine, "It's been... educational."
* Marty's adventures mean that he is ultimately named after himself.
-->'''Lorraine:''' Marty.. such a nice name.
* The SequelHook, with Marty and Jennifer piling into the [=DeLorean=] with Doc. Watch Jennifer's wide-eyed reaction to it all, and consider that, at this point, ''[[LockedOutOfTheLoop she has no friggin' idea what is going on]]''.
[[/folder]]

[[folder: The Animated Series]]

** Doubles as heartwarming when George finally gets it right and says "My destiny", only for Lorraine to respond with a soft "Oh..." and the most adorable smile ever.

** 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!"

* The entire sequence of Marty explaining the parking lot plan in detail, as he has to tell George that he's going to basically molest Lorraine to get her upset with him, and how visibly uncomfortable he is with the idea of it, but it gets better when George runs up gesticulating wildly with a bra in one hand, saying "You mean you're gonna touch her on her-?!"

* Marty reflexively jerking his face around to stare at Lorraine, horrified, when she dismisses his criticism of her smoking by saying he sounds like her mother (Marty's grandmother).

** A LuckyTranslation greatly improves this line in French. Marty's "heavy" is translated with an expression ("''C'est pas le pied''") which literally means "this ain't the foot", leading to the predictable retort:

* The hilariously awkward [[RippleEffectIndicator photo]] [[http://robotcosmonaut.tumblr.com/image/102323515066 of Marty, Dave, and Linda]]. Dave's standing there wearing a MickeyMouse t-shirt and waving like a huge dork; Linda is wearing those ''ridiculous'' 80's leggings and that [[BuffySpeak big pink bow thing]]; and Marty has a half-hearted smile on his face that basically says "I really, really wish I wasn't here right now".

** A subtle moment, but when Marty asks worriedly if Marty and Jennifer have turned into assholes in the future, Doc pauses for a moment, as if he's actually thinking about 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'... ''[[HaveIMentionedIAmHeterosexualToday gay?]]''\\

*** Not to mention Marty's radiation mask flipping down over his head, [[WesternAnimation/ToyStory Buzz Lightyear]] style, before he crashes.

--->'''Marty:''' Hello? Ah...excuse me? ''[points behind him awkwardly]'' Sorry about your barn. ''[Peabody begins shooting at him with a shotgun. Marty stumbles back and trips]''
--->'''Sherman:''' It's already mutated into human form, shoot it!\\

* Pretty much any of Doc's facial expressions throughout the trilogy. Creator/ChristopherLloyd's naturally overly-expressive eyes only make it better when he takes Doc's [[LargeHam hamminess]] UpToEleven.

*** Itself a CallBack[=/=]CallForward[=/=][[TimeyWimeyBall Whatever]] to Marty berating Doc and pointing out that you can't just walk into a store and buy plutonium.

** 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]]. ''Then'' it sounds like he's about to ask if he can borrow it so he can go to the lake with Jennifer.

'''Sam Baines:''' He's an idiot. Comes from upbringing. His parents are probably idiots too. Lorraine, if you ever have a kid like that, I'll disown you.

* "My God! Do you know what this means? ...[[ComicallyMissingThePoint It means that THIS DAMN THING DOESN'T WORK AT ALL!]]"
** Funnier thing is: It ''did'' work, given that he pulled "[[BrickJoke Coast Guard]]" (instead of, say, Navy).

** From the same scene, Marty's FreudianSlip when he's going over the plan with George. His execution in rescuing the situation by quickly replacing the word "Dad" with "Daddy-O" is priceless.

** FridgeBrilliance: You could easily point to that moment as Doc working it out that Marty just had HIS life altered via George standing up to Biff, and there were seemingly no dire consequences. So he figures "What the hell?" and pieces together Marty's letter of warning.
** Also, Doc sees how pathetic George really was, so he believes it might be for the best.

* Marty's adventures mean that he is named after himself.

* 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. 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.

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

[[caption-width-right:350:"I guess you guys aren't ready for that yet... but, your kids are gonna love it."]]

** And the follow-up, where Joey's mother says, "[[{{Foreshadowing}} He cries whenever we try to take him out, so we just leave him in there all the time]]." Not to mention that he's got a ''striped shirt''.

** When Marty leaves, Lorraine's parents comment on his behavior. Irony is abound, whilst Lorraine is staring lovingly after him.

* "My name is [[Franchise/StarWars Darth Vader]]! I am an [[Film/ETTheExtraTerrestrial extraterrestrial]] from the planet [[Franchise/StarTrek Vulcan]]!"

* George makes his attempt to ask Lorraine out while she's at Lou's for milkshakes. He orders one to calm his nerves first.

* 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. He did that again [[https://www.youtube.com/watch?v=AwKcPRCV6bI in 2009...]]
