Funny: Back to the Future

    open/close all folders 

    Part I 
  • 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 you look at the sign for the Twin Pines Mall (where Peabody's farm once stood) at the end of the movie - it is now called Lone Pine Mall!
    • And before that:
    Sherman: It's already mutated into human form, shoot it!
    Peabody: *fires a shotgun* Take that, you mutatin' son of a bitch!
    • And before that:
    Marty: Hello? Uh...excuse me? (points behind him awkwardly) Sorry about your barn. (BANG from shotgun, Marty stumbles back and trips)
    • And before THAT, the timejump 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.
  • 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. Doc looks) That's him.
    (scene then cuts to Biff's gang 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 "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 Florence Nightingale Effect. It happens in hospitals when nurses fall in love with their patients. Go to it, kid!
  • "If my calculations are correct, when this baby hits 88 miles an'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!
    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 car into a time machine, why not do it with some style?
  • Marty McFly 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...
    Lorraine: My name is Lorraine. Lorraine Baines.
    Marty: (with an audible squeak) Yeah!... but you're hooonote ... you're so hoooaah, 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.
    • 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.
  • When Biff and his gang are about to slam into the manure truck, they all shout in unison, "SHIIIIIIIIIIIIT!!"
    • And afterwards, when Goldie Wilson reaches the car, he takes one sniff and his reaction is one of "Whoo! That is disgusting!"
  • "My name is Darth Vader! I am an extraterrestrial from the planet Vulcan!"
    • Not to mention Marty using a Walkman with a Van Halen tape as an Agony Beam, 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 Brick Joke that Marty knocks George out with chloroform, and in the next scene George says he missed school because he overslept.
  • Marty's little comment after he tries to get George to ask Lorraine out.
    Marty: Jesus, George, It's a wonder I was even born.
    George: What?
  • Marty finally meets his Uncle Joey, the future jailbird, who is still a baby at this point in time:
    "So you're my uncle Joey. [taps the bars on the side of Joey's crib] Better get used to these bars, kid."
  • Near the mid-point of the film Doc and Marty work out how they're going to get George and Lorraine together... only for Lorraine to turn up at Doc's house and tell Marty that a real man stands up for the woman he loves.note  As she's saying this, Doc leans forward onto the covered DeLorean in a Head Desk.
  • Blink and you will miss it: The DeLorean is equipped with Goodyear tires.
  • A deleted scene, viewable in the various DVD and Blu-Ray releases:
    Marty: You know, this is the kind of thing that could screw me up permanently. What if I go back to the future and I end up bein'... gay?
    • Another deleted scene shows Marty peeking into a classroom window and seeing Lorraine cheating on a test. Even funnier is a joke version of the scene, in which Michael J. Fox shows up in a wifebeater, 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!!
      • Made even funnier when you see that he is visibly cracking up as they film it. And you can hear the crew laughing as well. But Christopher Lloyd amazingly keeps a straight face throughout.
  • "My God! Do you know what this means? ...It means that THIS DAMN THING DOESN'T WORK AT ALL!"
    • Funnier thing is: It did work, given that he pulled "Coast Guard" (instead of, say, Navy).
  • The flaming wind-up car running off the table and setting fire to some old rag. Doc's reaction is priceless.
    • 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 clocktower, and as detailed as a miniature film set.
  • The part when Marty tries to get directions from the guy in the cafe:
    Cafe Guy: *interrupting* Are you gonna order something, kid?!
    Marty: Uh, yeah. Give me a Tab.
    Cafe Guy: I can't give you a tab unless you order something.
    Marty: Okay, give me a Pepsi Free.
    Cafe Guy: You want a Pepsi, pal, you gotta pay for it!
    • And after that bit, Marty realizes he's sitting next to his future father. After Biff and his gang stop by to harass and torment George, 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.
      • Let's not forget 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.
  • "Lou, give me a milk! (dramatic pause) Chocolate!"
    • And the outtake where the glass slides too close to the edge of the counter, boucing off Crispin Glover's hand and ricocheting to the floor.
  • "I'm your density."
    • That whole scene is just hilarious. The way he awkwardly approaches Lorraine, holding his notebook out halfway over the table, and then Lorraine and her friends staring blankly at him as he breathes, "Density... has popped me to you." And she responds with a flat "What?"
  • 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."
    • Fridge Brilliance: 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.
  • The whole Running Gag involving Marty's vest and everyone mistaking it for a life jacket.
    Skinhead: The dork thinks he's gonna drown!
  • The "Who's president in 1985?" exchange is just outright hilarious because of Doc's hamminess.
    50s Doc: Who's President of the United States in 1985?
    Marty: Ronald Reagan.
    50s Doc: Ronald Reagan? The actor? Then who's Vice President? Jerry Lewis?! I suppose Jane Wyman is the First Lady! And Jack Benny is secretary of the treasury!
    • And later, once Marty shows Doc his 'portable television studio' (camcorder):
    50s Doc: No wonder your president is an actor, he needs to look good on television!
  • Two words: HOLY SHIT!
  • Marty's cover of "Johnny B. Goode": not the performance itself or the 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 see the audience silently staring at him like he's a lunatic. (And Strickland slowly stops covering his ears).
    • 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!"
  • Marty is talking with George while trying (and failing) to figure out how to open a glass Pepsi bottle (he seems to be trying to twist the cap off). 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.
  • The Sequel Hook, with Marty and Jennifer piling into the DeLorean with Doc Brown. Watch Jennifer's wide-eyed reaction to it all, and consider that at this point she has no friggin' idea what is going on.
  • Huey Lewis cameos as an audition judge, and tells Marty's band that they're "just too darn loud" when they play Lewis' own song "The Power of Love."
  • The opening scene. Marty uses a key under Doc's doormat to get into his lab (muttering "Aw, God. Disgusting..." when he notices the bowl full of 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...and is promptly blown across the room by the noise, destroying the amp in process, and crashing into a bookcase. "Rock 'n' roll", indeed.
    • Made even funnier when Doc calls afterwards to warn Marty not to use the amplifier.
    • Let's not forget 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.
  • 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 him starting to laugh as he leaves the camera shot.
  • Marty and Jennifer having their kiss interrupted by the "Save the clock-tower!" lady. Summarized best in this gif - just check out the look of exasperation on Marty's face.
  • 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 Freudian Slip 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.
    • And in a deleted scene, Marty tells George 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.
  • Marty's confrontation with Biff. The way he towers over Marty who has just casually tripped him up in the cafe, the camera catching a glimpse of Marty's classically scared face (just watch his eyes) as it happens (the fact that he's barely able to see over Biff's shoulders shows and it is hilarious). Marty then quickly pulls the oldest trick in the book by pointing at something behind Biff, punching him in the face when he's distracted and then taking off. Doubles as Crowning Moment of Awesome.
    • It doesn't help Marty's case when he punches Biff, because instead of noticing George, Lorraine gets even more lovesick than before. If you want something funnier, catch Doc's visibly speechless expression as she runs out of the cafe with her friends to the commotion outside where Marty's being chased.
    Lorraine: He's an absolute DREAM.
  • 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 behaviour. Irony is abound, whilst Lorraine is staring lovingly after him.
    Lorraine's Mother: He's a very strange young man.
    Lorraine's Father: 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.
    • A shot under the dinner table shows Lorraine caressing Marty's leg. His barely controlled discomfort changes when he abruptly stands up as she pinches his leg.
      • Not to forget, 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.
  • Marty's attempting at introducing George to Lorraine all but fails - George leans on the school locker casually but Lorraine is so focused on Marty 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 realisation of 'Nothing'.
  • 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.
  • The hilariously awkward photo of Marty, Dave and Linda. Dave's stood there wearing a Mickey Mouse t-shirt and waving like a huge dork, Linda is wearing those ridiculous 80's leggings and that big pink bow thing, and Marty has a half-hearted smile on his face that basically says "I-really-really-wish-I-weren't-here-right-now".
  • Doc's penchant for using big words when smaller words could easily suffice, such as calling the Enchantment Under the Sea Dance "A rhythmic ceremonial ritual".
  • At the climax of the movie, Marty is about to set off in the DeLorean to get back to 1985. 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 - which starts up the engine again. Marty's wide eyes and Adorkable gasp at this is hilarious.
  • From a 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 pinch him to confirm that this is real. He gets a slap instead.
    Marty: (holding his cheek in pain) Yeah, that'll do...

    Part II 
  • Doc about what would happen if Jennifer meets her future self:
    Doc: I foresee two possibilities. One, coming face to face with herself 30 years older would put her into shock and she'd simply pass out. Or two, the encounter could create a time paradox, the results of which could cause a chain reaction that would unravel the very fabric of the space time continuum, and destroy the entire universe! Granted, that's a worst-case scenario. The destruction might in fact be very localized, limited to merely our own galaxy.
    Marty: Well, that's a relief.
    • The part where the two Jennifers meet can also cause laughs. They gasp in unison, exclaim, "I'M OLD!" and, "I'M YOUNG!" at the same time, and faint in unison.
  • In the future, a scene occurs which mimics the manure truck scene mentioned above, only Griff (Biff's grandson) is the victim. Future Biff is a bystander and comments "There's something very familiar about all this."
    • Even better, in 1955. Future Biff is hanging back, waiting for his moment to talk to 1955 Biff. He overhears young Biff and the mechanic talking about the first manure encounter. Biff says "The manure! I remember that," and he sounds amused by the memory. Between that and his correcting young Biff on his malapropism, that timeline's Biff was able to achieve a pretty decent level of maturity as he aged.
  • Speaking of manure, Biff's reaction to his second crash with the manure truck is hilarious. He's so upset that he looks ready to cry.
    Biff: Manure! I hate manure!
  • "I think he took your wallet! I think he took his wallet."
  • Strickland scolds Biff for putting alcohol in the punch, and then he goes into his office and has a drink himself.
  • The entire scene between old and young Biff.
    Young Biff: Now why don't you make like a tree, and get out of here!
    Old Biff: (slaps young Biff) It's "LEAVE"! You idiot! "Make like a tree and LEAVE". You sound like a damned FOOL when you say it wrong!
    • And earlier on, Biff butchers yet another one while he's harassing Lorraine:
    Biff: That's about as funny as a screen-door on a battleship!
    Marty: (exasperated) "Screen-door on a submarine", you dork...
  • "I don't believe it!"
    Doc: It's remarkable that Old Biff would have chosen that particular date! It's almost as though that day is central somehow, as though it were the focal point of the entire space-time continuum! *beat* On the other hand, it could just be an amazing coincidence.
  • The 2015 dog-walker.
  • "Do we become assholes or something?" coupled with the look on Doc's face as if he's thinking about for a second.
    • I kinda like that he responds by saying Marty and Jennifer turn out fine, which we find out later is a complete lie.
  • Marty pulls the Newspaper Dating trick, only to find out it's alternate-1985 Mr Strickland's porch. The first thing he says, carrying a loaded shotgun and pointing it at Marty? "So you're the son of a bitch who's been stealing my newspapers!"
  • The Jaws 19 ("This time, it's really, really personal") ad and its holographic shark. Marty screams in horror as it comes at him, and when it disappears...
    Marty: The shark still looks fake...
    • It's directed by Max Spielberg.
  • Jennifer expresses excitement at the thought of seeing hers and Marty's wedding when taking her first ride in the time machine. This excitement deflates after she finds a picture of them as newlyweds.
    Jennifer: (in horror) I get married in the Chapel O'Love?! I gotta get out of here. (drops the picture on the ground and heads for the door)
    • Freeze-framing a shot showing the picture reveals that not only will Marty cheap out on where to hold the wedding, but he will wear a shirt with a tuxedo pattern instead of a suit, and Jennifer will wear a ridiculously short dress.
  • The part in the outtakes when the Western Union man accidentally traps part of his jacket in his car's door.
  • While the Running Gag of Marty being called chicken was done a lot, special mention goes to Old Marty when Needles dares him to do something illegal.
    Old Marty: Nobody calls me chicken Needles. NOBODY!!!
    • Also the first time that trope shows up, when Griff and his gang calls him that.
    Marty: Nobody. Calls me...
    Marty: (nervously giggles)... chicken.
    • And the third time, when he is confronted by Biff after being distracted by the sight of 1955!Marty saying goodbye to his future parents:
    Marty: Nobody...calls me...chi— (WHAM! Marty is knocked into a wall by 1955!Marty slamming the door open in a hurry)
  • Marty to his half-conscious future son after witnessing him getting nearly pulverized by Griff, then deciding to handle him himself:
    "Stay down and shut up!"
  • Doc gives money to Marty for buying 50s clothes, and tells him to buy "something inconspicuous!" One Gilligan Cut later, Marty is outside Biff's grandma's house with his walkie-talkie, wearing a not-so-inconspicuous leather jacket and a Blues Brothers-esque hat and shades combination. The way that he slides into the camera shot before pulling out his walkie-talkie just adds to the hilarity.
  • When Marty takes the Almanac from a TKO'd Biff (after being punched out by George), the latter wakes up just in time to see Marty reaching into his pocket. Marty's response? He punches Biff in the face to knock him unconscious again. Bearing in mind that he is surrounded by a crowd of onlookers.
  • Marty interrupting his mission to stop Biff's goons just so he can bob along to his own rendition of Johnny B Goode.

    Part III 
  • Doc spilling the truth about the future after losing Clara. Of course, he's been hitting up the sauce to drown his sorrows, and his delivery of the truth is completely deadpan and depressing. It sounds exactly like the ramblings of a miserable drunk.
    Doc: And in the future, we don't need horses. We have motorized carriages called automobiles.
    Old-Timer: If everybody's got one of these auto-whatsits, don't anybody walk or run anymore?
    Doc: Of course we run, but for recreation. For fun.
    Old-Timer: Run for fun? What the hell kind of fun is that?!
    • And what makes this funnier? The bartender states that he hasn't had any of the whiskey he's holding. He isn't drunk at all.
      Bartender: (amused) He just likes to hold it!
  • The fact that Doc tells Marty the cardboard Indians at the drive-in won't be there in 1885 when he drives the DeLorean towards the movie screen... except they are, and they're REAL.
    • Marty running away from the bear is pure slapstick.
  • Doc passing out after drinking whiskey.
    Marty: How many did he have?
    Bartender: Just the one.
    Marty: Just the one? Come on, Doc!
    Bartender: Now there's a fella who can't hold his liquor.
  • The old-timers' reaction to seeing Marty in his goofy pink "Western" outfit:
    Old-Timer #1: Take a look and see what just breezed in the door.
    Old-Timer #2: Well, I didn't know the circus was in town!
    Old-Timer #3: Musta gotten that shirt off'n a dead Chinee.
  • When Marty identifies Buford Tannen as "Mad Dog" Tannen, everybody in the saloon either runs away or hides under the tables.
    • Then Buford makes Marty "dance" (read: force him to constantly dodge bullets getting shot at his feet), and Marty ends it with a moonwalk - you can even hear him singing "Billie Jean" under his breath. Buford's WTF look really sells it.
  • Doc handwaving away the moral complications to train theft: "We're going to hija—borrow the locomotive..."
    • Also a brief Heroic BSOD when Doc momentarily remembers how he unintentionally changed history:
    Doc: We'll drive the train towards Clayton...Shonash Ravine.
    • And in the end, after Marty gets back to 1985, we see the ravine is called "Eastwood Ravine". This borders on Black Comedy, because as far as the 1885 residents of Hill Valley knew, "Clint Eastwood" was killed in a horrific train wreck (the same morning that he got Buford Tannen arrested, too!), and the ravine was thus renamed in his honour.
      • Even funnier, as Marty is coming to a stop, people from the main road are all staring in bewilderment at this DeLorean on the train tracks - and possibly at Marty in his full western outfit, too. All Marty can do is smile and wave awkwardly. Of course, this is followed by a massive Mood Whiplash as the time machine is destroyed by an oncoming train.
  • 1955!Doc reading the letter from 1885!Doc.
    Doc: "Please take care of Einstein for me." Einstein?
    Marty: "It's your dog, Doc. Einstein, that's what you call your dog in 1985.
    Doc: It actually flew!?
    Marty: Yeah, you had a hover-conversion done in the early 21st century.
    Doc: Incredible...
  • The scene where Marty wakes up alone in the house (with the heavy implication that Doc spent the night with Clara) and realizes that he's alone with the gun he was given the night before. The first thing he decides to do? Put on his cowboy hat and gun holster, stand in front of a mirror, and tote his gun quoting Robert De Niro and Clint Eastwood. ("You talkin' to me?" and "Go ahead. Make my day.") All while wearing his silly 1885 one-piece pajamas with a Wardrobe Malfunction.
  • "Everybody, everywhere, will say that Clint Eastwood is the biggest yellow-belly in the West!"
  • When Marty tries to forfeit his showdown with Buford.
    Buford: Wha? Forfeit?! *turns to his lackey* What's that mean?
    Mook: Uh... It means you win without a fight!
    Buford: Without shootin'?! He can't do that! *turns back to Marty* Hey, you can't do that!!
    • A bit later, while he's giving Marty the count of ten to come out of the saloon.
    Buford pauses, then looks at one of his mooks, who holds up seven fingers
    Buford: Seven!
  • Continuing the Running Gag of Marty using 1985 slang:
    Marty: Hey, Frisbee! Far out! *walks away*
    Seamus: What was the meaning o' that?
    Maggie: It was right in front of him!
  • How about Buford being so pissed off after his confrontation with Marty at the Town Festival he sounds like he's about ready to cry:
    Buford: Come boys, let's go! Let these sissies have their party!
    • When he originally planned the duel.
    Buford: Let's finish this right now!
    Mook 1: Uh, not now, Marshall's got our guns.
    Mook 2: Tomorrow, we're robbing the Pine City Stage...
    Buford: What about Monday? Are we doing anything Monday?
    Mook 1: No, Monday'll be fine, you can kill him on Monday.
    Buford: I'll be back this way on Monday!
  • Marty and Doc exchanging Catch Phrases.
    Marty: Great Scott!
    Doc: I know, this is heavy.
  • When Clara asks the Barbed Wire Salesman if Doc was the man suffering heartbreak at the saloon, she manages to blurt out a rather flattering description of him (could also belong under Heartwarming Moments).
    Clara: Excuse me, but was this man tall, with great big brown puppy dog eyes and long silvery flowing hair?
    Barbed Wire Salesman: You know him!
  • One of the outtakes has Seamus McFly bring home a plush Roger Rabbit for supper.
    • In another, Doc's goodbye to Clara gets interrupted by the horse farting, which Christopher Lloyd acknowledges without breaking character.
      Doc: (completely serious) I've come to say goodbye. We both have.
    • The Roger Rabbit outtake may be funnier when you consider that Christopher Lloyd was in both movies, playing wildly different characters.
      • Even MORE hilarious, Charles Fleischer, the voice of Roger Rabbit, is in Part II as Terry.
    • In the outtakes, the old timers offer a different commentary on Marty's "western" garb.
    Old Timer #1: My son come home from once back east in them fancy-ass duds like that.
    Old Timer #2: What did you do to him?
    Old Timer #1: Shit, I forgot.
    • Thomas F. Wilson based his portrayal of Buford Tannen on Lee Marvin in The Man Who Shot Liberty Valance, but in one outtake, he inadvertently channeled another western star.
    Tom: What's your name, pilgrim? "Pilgrim?", what am I, John Wayne?
    • And another outtake features Doc and Marty talking about the plan to get back to 1985 next to the unfinished bridge. As they start to head back, Christopher Lloyd accidentally sandwiches Michael J. Fox between the two horses.
    Michael: Yo, Doc. You're squishing the shit out of me!
    • The next blooper has Marty Faking the Dead after being shot by Buford. As the camera moves closer to Fox lying on the floor, a fly seems to think he's really dead and lands on his lips. Cue him blowing it away then cracking up laughing.
  • The climatic showdown between Marty and Buford is both hilarious and awesome. Marty decides not to use a gun against Buford and drops it on the ground - but when he IS shot, it turns out that he's wearing a stove door under his poncho (a Shout-Out to A Fistful of Dollars note ) - as Buford finds out the hard way when he tries to punch Marty in the stomach. Marty then takes it off and gives him a good whack in the face with it. When that is also dropped on the ground, Marty still beats the everloving shit out of Buford - who then fittingly, collapses into a manure cart after crashing into a tombstone (and not just any tombstone, but the blank that was going to be Doc's) from Marty's punch and making him dizzy.
  • The 1955 Doc and Marty discovering the 1885 Doc's tombstone has two darkly comical moments:
    Marty: (reading) "Erected in eternal memory by his beloved Clara." Who the hell is Clara?
    Doc: Marty, please don't stand there!
    (Marty discovers he's standing directly over the grave)
    Marty: Oh, sorry! Gotta take another picture. (he takes the picture)
    Doc: (reading) "Shot in the back by Buford Tannen over a matter of eighty dollars"!? (to Marty) What kind of a future do you call that?!
    • Later, when the 1885 Doc sees the picture.
    Doc: "Shot in the back by Buford Tannen over a matter of eighty dollars"!? September 7th? That's this Monday! Now, I wish I'd paid him off!
  • Here's a blink-and-you-miss-it moment: After Marty wakes up at the McFly farm and comes face to face with his great-great-grandmother, he lifts up the blanket to check if he's still wearing his pants (luckily he is, this time).

    Telltale Game 
  • When examining the 1931 Newspaper in the inventory which changes from Doc being killed on the courthouse steps to being killed on a paddywagon, Marty's comment will most likely echo the gamers comment.
    Marty: Now that's just not fair!
  • The sequence where Emmett and Edna trade insults in Episode 2 while Doc rescues Einstein from the courthouse roof.
  • In Episode 3, Marty has to distract a brainwashed Biff, which is accomplished by pointing out various nearby objects.
    Marty: Biff, look! Girlie mags!
    Biff: Boobies?!
  • Early on in Episode 4, Citizen Brown is strapped to a wheeled bench right in front of a giant speaker while Edna and a guard look on. Marty plugs his guitar into the speaker, then jumps down onto the bench dramatically intending to play a loud chord and blast himself clean out the door with Brown. He hits the strings... and only moves a few inches, completely subverting the awesomeness of the maneuver.
    Marty: Okay, that was a little less dramatic than I'd expected.
  • In Episode 4 Marty informs Doc that his alias at the moment is Carl Sagan.
    Doc: The "billions and billions" guy?
  • In the ending of Episode 5 when Doc and Marty are dumbfounded by Edna ending up with Kid Tannen.
    • "Don't say anything. Let's just walk quietly into the lab and hope there are no more surprises..." And then the Mind Screw of an ending...
    • The shout out to the end of the first film.
      Future!Marty: Bring [Marty] along too! This concerns all of us!
      Marty: What does you mean? Does something happen to us?
      Doc: Do we turn into assholes or something?
      • Heck, this whole scene is a hilarious Up to Eleven parody of the first movie's ending. Three Martys, with three DeLoreans, from three alternate futures show up, and immediately start bickering over which one of their timelines is the most important, and which one Doc should be helping - all voiced by MICHAEL J. FOX, no less! Doc and Present!Marty's reactions? They leave in their own time machine.
  • If you examine the mop in Episode 5:
    Marty: The top of a mop. I can flop it on a cop. I can swap it for a top. I can...I think I'll stop.
  • Marty playing around a Theremin Booth enough times to do a moonwalk in Episode 5.
    • Which earns you a Trophy.
  • When refreshing 1800s!Edna's memory of what happened, there are various prompts you have to give, various questions to answer - and there are, as usual for the genre, several wrong guesses included. But when the time comes to remind her of the villainous saloon owner's last name, the only option is Tannen.
  • In episode 1, at a certain point you can ask Doc about Kid Tannen. He explains that Kid will be serving a life sentence in prison in the near future within 1931. This conversation prompts:
    Marty: Wait, if Biff will be born in 1938...
    Doc: As I recall, he escaped in 1937 for about three hours.
  • At the same time, Marty expresses concern that telling Doc's younger self about the equation's solution might screw up the time stream.
    Marty: So...?
    Doc: It'll be fine.
  • In Episode 2, when Doc disguises Marty as a 1930s mobster, he tells him that the fake mustache is essential to not being recognized, and that he is easy to disguise with his "nondescript features". The lingering look of disappointment on Marty's face when Doc says this is good for a laugh. Along with him muttering "nondescript...?"
    • This is referenced later in the same episode, if you ask Zane to draw a caricature of Marty. He comments that it doesn't really look like him, and Zane replies that "there wasn't much to work with".
    • Made funnier by the fact that Marty's face is anything but "non-descript".
  • "WHAT THE FRUG?!?!"
  • In episode 1, Marty tracks down where elderly Edna Strickland lives, and brings back her missing shoe, holding it aloft for her to see from the upstairs flat window. A woman walks by and stares at Marty quizzically as he does this; he just responds with a shrug before she leaves.
  • At the start of episode 3, Marty has crashed the DeLorean into a billboard after Doc has been erased from the timeline. Marty decides to clear something up if you click on him:
