A few of "Emma's Words of Wisdom" moments probably count.
Including "Emma's Words of Wisdom - AGAIN !" in "Kids React to Charlie Sheen".
The Eye Take of Morgan during the "le Internet Medley" video. She was laughing, and suddenly went "O_O what the heck?!" when the ALL YOUR BASE ARE BELONG TO US part barges in. Her expression is just priceless.
Morgan's "answer" to the question whether the video was real or fake during the "Kids React To Greatest Freak Out Ever" video.
Also don't forget her very nonchalant "This boy's a train wreck." in the same video.
Morgan's Random Animal Sing-a-Long from the Keyboard Cat video.
The kids then trying to replicate what Gollum sounds like:
Benny Fine: What does Gollum sound like? Everhet(flapping his hands together): Precious! Elle: My precious! Seth(whispering tone): My precious! Troy(looks towards the camera, also quiet-sounding): I don't want to see The Hobbit! Cooper(wiggles fingers): My precious! (Benny giggles, Rafi says "Ah!" in amusement, then Cooper repeats)
Emma R. reacting with sheer horror at that one screencap.
There's just something weird about Benny Fine sticking to the the cards, to the extent that one particularly elaborate question is being fielded by four-year-old Cooper.
Benny Fine: Some people think there's a lot of deep meaning and messages hidden throughout this video. Other people say that no, it's just random. What do you think? Cooper: (possibly latching onto the last thing she heard) I think it's just random.
In the middle of the video, Jake randomly asks why the puppets are British.
In Kids React to Gay Marriage, while it's a more serious topic, most of the kids don't understand what's going on at the beginning, but Maksim, one of the youngest, just says matter-of-factly, "So they're gay?" It's funny how sometimes the youngest kids know the most.
The Fine Bros: What did both of those videos have happen in them?
Maxim: Justin Bieber married a guy...
The Fine Bros: That wasn't Justin Bieber!
During "Kids React to Rhett & Link", the kids are asked to do come up with something to say before they did something stupid that led to their death.
Derek:A Weeping Angel! Hold on, let me rub my eyes. (Benny and Rafi crack up off-camera)
During the reaction video on Disney's Frozen - "Let It Go" (Multilanguage), Lucas immediately took off his cap once Elsa began to sing.
"Kids React to Rotary Phones": The Fine Bros ask how people would text on a rotary phone. Takes the kids a while to catch on that it's a trick question.
The Fine Bros: There was no texting back then.
Brooke: Then how-? If they wanted to talk to their friends, how-? Ooooooohhhh. That's how. They would call.
Just the fact that Dash described the old rig as "very hipster."
The bonus material. New girl Sydney learns that the thing in her hand is called a 'floppy disc', and does a silly little dance for no discernible reason.
And then later on she says 'I'm gonna look for that on Google' like it's the most normal thing.
Jayka seems to think DOS stands for 'Disk of Saving'. Too many RPGs on the mind there?
"Kids React to Luigi Death Stare". Naturally the Fines convince the kids to try and replicate Luigi's new killer move - and then Lucas does his rather well-practiced Kubrick Stare instead. Not to mention that the Fines have a fake mustache on hand.
Emma's stubborn refusal to participate in the Q&A is hilarious.
Benny: Who's your favorite turtle?
In "Kids React to Skip It" the rest of the kids give it a go... except for Evan, who just tosses and kicks it about presumably out of frustration.
In the bonus material, Mahrly is seriously miffed at learning that she'd been beaten at it by Lucas. And Dash's initial attempt to get the ball moving around his foot involved moving his foot around the ball. You can see where that is going.
The very last line of the episode, when asking all of the kids if they would like to own a Skip-It, Derek and Rafi have a good exchange:
Derek: I would enjoy having one... Can I take this o-
Derek: Okay then.
Chloe drops the camera as soon as she gets her hands on it.
I guess so as long as he wasn't like "Come inside." (does creepy funny face) (imitates Salad Finger's voice) Can I have your rusty pen? Eric: It's like they took my diary and put it in videos!
Appropriately enough their first episode in October, "Teens React to Slender" is filled with these. One particular moment is Kostas getting excited over finding the first page, so much so he jumps out and hits the microphone, and only milliseconds after apologizing he gets caught.
Snap-polls are a recurring thing across the React series. The one here starts with a landslide vote against child pageants; then Lia feels merely iffy about her vote, and the numbers update in fractions. And then Rumor, who's admitted to Bile Fascination with the show, causes the fractions to balance out.
The same thing happened in the Bill Gates vs. Steve Jobs poll. Ethan said he was torn because he uses a Mac but prefers a PC, so his vote caused the poll to also be updated in fractions, only for Rachel to immediately have her own indecision because she said she'd love to work for either Apple or Microsoft, so the fractions evened back out.
Rumor: You guys actually found something I don't like!
The Mondegreens of "Gangnam Style", capped by Isaac with "Open condom store?"
And earlier, Rachel cutting herself off mid-sentence when the toilet scene pops up, followed by her reaction after the video ends (made funnier by the trepidation in her voice): "Hi guys, how was your day?"
In teens React to Attack on Titan, Josh starts talking about what happens later in the show and the Fine Brothers mute his voice and put on a caption reading "We apologize to any lip readers who may now have had Attack on Titan spoiled for them"
Richard: I don't think that's going to make it in a retirement home.
Fine Bros.: What would you call this dance? Virginia: Butts for sale?
From the same, upon realizing that the first video was an instructional Don immediately gets up so he can try it. Once it becomes apparent what it is, he's shown back in his seat while making a Face Palm.
Don: Yes, I see the interest now.
Bill gets a huge belly laugh out of Trevor's line "Nice new tits by the way" during "Elders React to Grand Theft Auto V".
Out of all the reactions, special note should be made of Rock's. The poor old guy practically goes Laughing Mad.
"Elders React to PewDiePie". The initial reactions are either of the two extremes: Rock and Victoria, in particular, spend half of the video in stitches, with Vera and Yehuda not far behind them, and Pamela is simultaneously offended and amused; meanwhile, Rhoda, Laura, and Melvin are disconcerted, Barbara is vocal in her opposition, and Robert is left completely without words.
Elders React to #Selfie. Despite the generally negative reaction to the music video, the Fines have a camera phone ready for the elders to try taking their own selfies, and pretty much all of them have the gist of it down... then we go to Rock, who Crosses the Line Twicewith a Scotch tape selfie. Yeah, you read that right.
When they are given Google Glass to react to, one of them gets a porn search ("Glass, take a video" got turned into "elastic dick video" by poor voice recognition) instead of taking a video like they were asked to try out.
Subverted, though, since Tay does clarify that he's grateful for the success the song has given him and doesn't seem to regret it in the least, aside from a passing mention of a "love/hate relationship" with it.
Episode three ("YouTubers React to Rewind YouTube Style"): That awkward moment when MysteryGuitarMan realized that "Rewind YouTube Style" and YouTubers React were Not So Different.
Brittany and Wong Fu Productions both panicking as they realize they're about to be rickrolled again.
The Fine Bros doing their own spin on the Goat remixes in Episode 6... with the YouTubers.
Everybody's horrified reactions in Episode 7 to the Knife Game song.
At one point, Benny and Rafi offer their guests the chance to do it. Most people choose not to, apart from Tay who "cheats" by pointing the knife the wrong way up, and Shane moves to do it, prompting a horrified "no" from offscreen as they think he actually will. Jordan Maron actually lampshades the fact nobody wants to do it as well.
"YouTubers React to Japanese Commercials". The commercials are indeed funny themselves, but Hannah Hart compares her efforts dating girls to one of them, while Felix recommends that the creators of the commercials go into horror games. At one point for one of the commercials, Harley just remarks, "I don't wanna sound racist... but, how very Asian."
Some of the individual reactions are gold. Especially the ones to the Tarako spaghetti sauce ad, which features a small doll ominously rotating in front of a mortified child:
A large group of them just imitate the look of utter terror on the little girl's face.
Shane Dawson: Have you seen my videos?! I could do this in my sleep!
Trust the YouTubers to mess around with a more "heavy" topic like Look Up:
Put down that phone. Shut down your display. Stop watching this video and live life the real way. Shane Dawson: All right. (closes the laptop)
Benny: So what was the message of this video? Harley Morenstein: Put down your phone and f(caw!)k bitches.
"Try Not To Laugh Challenge": Aside from the various stars bursting into laughter, which can be quite contagious, there are moments where you can tell the people are taking the challenge literally. Captain Sparklez's reaction to the Ladder Goat being murdered is simply "Poor goat. He didn't deserve that". He also has an adorkable moment where he's made it through the challenge and simply goes "not funny".
Hank Green mistaking the guy who did ladder goat for PewDiePie. Then he finds out that he gave in and laughed because he made the mistake, something which is essentially treated as an Epic Fail.
In the bonus footage, Shane Dawson essentially has a Rage Quit from watching the entire thing again when he forcibly bursts into laughter and keeps thrusting in time with the Stormtrooper air humping, begging to stop.
"Rejected": The video starts with Smosh squeeing out over the titular animation alongside Timothy Delaghetto, which sets the tone for the whole video. Then we cut to the second animation and Ingrid and Olga's horrified reactions at the guy growing an extra head.
"MY ANUS IS BLEEDING". Again, Harley is laughing himself silly alongside Philip DeFranco, whereas Tay deadpans "he needs to see a cloud doctor" and Felix simply comments "I guess it's that time of the month again". When later asked what was happening to the cloud, Tay comments "I didn't learn that in meteorology".
Hank notes the lampshaded Sanity Slippage of the cartoons, commenting that he felt there was no sanity in the whole thing to begin with.
"YouTubers React to Vines". Shane Dawson of all people thinks that Everybody Spurts is gross. Tay Zonday just comments that the people doing it need to see doctors, and Jordan Maron mistakes it for the REM Vampire meme (which doesn't exist).
Joe Bereta and Elliot Morgan then start having a mock argument as to whether or not the other is giving good advice to people starting out on Vine.
At the end of the video, everybody does an "Everybody Hurts" style clip. Each one is fantastic. Special mention must go to Jordan's and Shane's, however, as Jordan is seen doing it with a towel over him (te only one to do so) and Shane tries doing it with mayonnaise but can't even do it for the 7 seconds a Vine video would take as he finds it so disgusting.
The bonus video for it has Jordan reacting to Ryan Gosling Won't Eat His Cereal by saying "he doesn't want it, stop trying to feed it to him", after the titular protagonist throws it into a bookshelf.
Tay describing Vine as a 6 second version of Popeye.
The bonus reactions expand on the "Everybody Spurts", where Phil can't keep doing it because it's just too funny, Ryan Higa can't keep it down because the liquid he's using is really cold, Tay does a disturbing Slasher Smile, Ingrid is unable to stop herself laughing, Jordan also can't stop himself laughing and you can hear Benny and Rafi laughing from offscreen, and Shane squirts an entire thing of mayonnaise in his mouth.
"K Pop" (aka "Korean Korean Korean 'fantastic, baby' Korean Korean Korean.") Trisha and Meg squeeing out over the K Pop videos. This is followed by Ian and Anthony both dancing along, only for Anthony to randomly start rubbing his nipples, then in the next reaction Anthony asks if he's seen one of the girls in Psy's videos, at which point Ian says "No, you're just being racist"... then quickly wonders if Anthony is in fact right.note The girls in each of Psy's videos are in other Korean girl groups, and not in Girls' Generation. In the third one, Tay obviously cannot take the boyband serious and starts making up fake lyrics.
The various Mondegreen moments that people have throughout. In the Girls' Generation video, Anthony wonders if they are singing "I got a boy on my chin", then can't keep himself from laughing every time the line comes up. Tay doesn't dare to guess, just commenting "I need Google Translate".
When asked what she thought of the first video, Rosanna just says "Fap fap fap fap fap", and again for the third video.
DeStorm noting the three Porsche cars in the background of the last video, telling Rick Ross that he had better watch out.
"YouTubers React to One Direction's Best Song Ever". Throughout the video, it's obvious that Mark and Todd from Barely Political consider the entire video to be torture. There are so many thinly veiled insults towards the band too.
Zoella's reaction to every photo presented to the band: "Less clothes!"
"YouTubers React to Farting Preacher," especially the end where the Fine Bros put fart noises over everyone, even those who didn't consent to it.
Zoella: "I would hope that [the Farting Preacher] would have a sense of humor and find them funny. I think if somebody did that to me, I would find it hilarious." (fart noise)
Philip DeFranco's reaction to being told that the preacher was a televangelist during the 80's and 90's.
Philip: "So question, before you finish it; did he die of a drug overdose, or did he go bankrupt?"
Benny: (brief pause) "He didn't die, but he was in courts for stealing all these people's money."
Philip: (sarcastic) "What? I am so surprised."
And then right after that:
Benny: "But he lives on forever as the Farting Preacher."
Catherine: (busts out laughing, in between laughs) "He wanted so much more out of life! And he's just the Farting Preacher!"
They even did an entire video filled with fart noises, in the style of the source video. The farts serve to bleep out swearwords, play over the title sequence, and randomly pop in over random words that people are saying.
The Fine Bros.: "What is your advice for someone trying to promote something on YouTube? What is the best way to go about it?"
Kalel: "I would say... boobs." (Anthony bursts out laughing)
And before that, when one of the people getting punked is a black dude, leading to Anthony letting out a deep "aw HELL naw!", which Kalel immediately digs at.
YouTubers React to Bunnies Can Fly...Proof:
Question: "What do you think they said to their daughter once the camera turned off?"
Harley: "I would go right to the library and get one of those big white books, you know one of those awesome white books that has all the pictures, and just get the bird one. I'd be like 'You see how cute these birds are? They need to obliterate things like that bunny to live. You want the birds to die? No you don't. So the bunnies must die.'"
When Catienote aka Boxxy is about to cry trying to explain Kiwi, she looks offscreen and we get this gem.
Catie: Oh, I found tissues.
In the bonus video for the Short Viral Videos episode, iJustine has an insane fit of laughter watching "Go! BWAAH" and "Sneezing Baby Panda". How do the Fine Bros help her calm down? By showing her "Go! BWAAH" again. Her face is just priceless.
In "Little Baby's Ice Cream", Lia gets freaked out by the commercial and turns away out of fear.
Pretty much all of "Youtubers React to Shrek is Love, Shrek is Life" for the same reasons as "DyE Fantasy" above, but special mention goes to the intro. Normally it just says what they're watching, with a few of the comments that had suggested it. This time, however, due to the large amount of requests, the comments fill the screen.
Jack: Seen it. Fap to it.
In YouTubers React to Sesame Street: Old School, they tell them that the DVD comes with a warning saying "For adults only". MatPat's reaction to it? He talks like he's doing one of one of his videos.
MatPat: Really? Really? I'm assuming its for scenes like that which are too agressive or agro for- for the typical preschooler.
One of the skits they give a description of.
One of the Fine Bros.: A character with a servere mood disorder who's very mean to everyone he meets.
Tay: That's Oscar. That made it into Sesame Street.
Shane Dawson attempting to hang himself, and Link Neal just leaving the rope around his neck for the rest of the video.
Considering the way she perved on Justin Bieber a while back, it's funny to see how much Justine Ezarik had read up on Ylvis.
Seth's reactions to Slender are some of the most hilarious to date.
Nearly everyone's reactions to Goat Simulator count as this. Special mention goes to Eric. His whole session is hilarious.
Eric: (game starts glitching, causing his goat to spin around) Satan?!
When they revisit Goat Simulator after a new patch:
Eric: (locating the Deadmau5 level) This is the whitest dance party ever!
Outlast has some of the biggest reactions yet. Special mention:
Poor Seth getting a jump from something not really intended as a Jump Scare (the body was already just hanging there). Not helping things is the way the actual jump scare looks like it gave him an aneurysm and brown pants at the same time.
Tori reaching for the mouse with a hand over her eyes.
A Black Comedy Burst when Rae checks out a headless corpse, then manages to locate a cabinet full of severed heads. "I found their heads!"
Morgan saying Doc Louis looks like Stan Lee from The Office.
Josh is the only one that landed a hit to Mike Tyson. He gets knocked out a few seconds later. Also, earlier in the video, Josh knocked down Glass Joe with two uppercuts, but Joe gets up after a one count.
Although she does manage to win one round despite being reduced to Ludicrous Gibs. Labib, true to form, fails to win it despite having the intact head make it to the finish.
The Santa game with the panel that says "Move you little sh*ts!" Adam winds up channeling PewDiePie.
This little gem from Labib
Labib: "First I said Santa was fake, now I killed him. I'm like public enemy number one right now. And I'm also Middle Eastern so now you're gonna be like "This terrorist does not like Santa, and he just killed him too" Next episode, I'm gonna be in Guantanimo Bay."
Ethan James: I'mma put some money down... Benny: No gambling!
To be fair, he did win the tournament.
Rumor has enough of Ethan James' shit during Super Smash Bros.
Rumor: "Ethan James needs to stop talking in third person... What's Ethan James now?!"
The Elders various reactions to Unfair Mario, ranging from confusion, anger, and especially frustration.
Vera: "How long do I have to torture myself over this?"
Rock, however, laughs everytime Mario dies.
During Sonic Unfair, many, if not, all the teens succumb to Heroic BSOD during gameplay.
In the end, Jeannie (122 deaths, and the only one not to complete the first act), Sam (88 deaths, Act 1 completed), Rachel (100 deaths, Acts 1 & 2 completed) and Rumor (87 deaths, Acts 1 & 2 completed) quit the game. Darius completes the zone with 128 deaths, while Ethan James completes the zone with 87 deaths.
Darius saying that he wants to punch the face of whoever made this game.
In Episode 2 of Lyric Breakdown, you can see the exact moment when Jade, who originally though the subject song was something by Kid Cudi or Kanye West, slowly realizes it's really "Smells Like Teen Spirit" by Nirvana. She immediately starts apologizing for the mistake while laughing hysterically.
Labib, on the other hand, looks like he wants to hide under a rock when Benny reveals which song it is.
Bboy2012ss: How do I avoid the friendzone? Michael: "Find out what she likes, find out who she likes. Do exactly what she likes from the guy that she likes. [...] So if she likes Johnny, you follow everything that Johnny does. If Johnny plays football, you play football. If Johnny eats hotdogs, you eat hotdogs." Miracle: "If Johnny has brown hair, dye your hair brown." Michael: "Exactly." Miracle: "That's what you do!" Michael: "If Johnny go poopoo at 2 o'clock, you go poopoo at 2 o'clock!" Miracle: "That's how you roll!" Michael: "Go like Johnny." Miracle:"Be Johnny."
Benny: "Do you have any idea who those two guys are?" Series of kids: "No. No. Nope. No. No. No. No." (Shot of Anthony watching, his face slipping further and further into a sad pout with every "No".) Zak: "I think they're Smosh?" (Anthony's face immediately lights up.)
Kids React at the Daytime Emmy awards. The kids get in line and announce their age, presumably for archiving - Jake is 12, one of the twins calls out 11, Elle says 10, and Dylan is nearly Pavlov'd into saying 9 (should be 10).
Later, one of the teens asks if you can just make a Minecraft map with LEGO. Jordan disagrees strongly with this.
Adam says that the name of Jordan's channel would have given him the impression of it being from a homosexual male. Jordan rapidly points out that it was for a dare.
The Fine Brothers did something for April Fools' Day 2014, by attempting a new series. Key word here is "attempting". Cats, no matter how cute they are, how old they are, or if they're actually YouTubers in cat costumes, cannot give a proper response, it turns out.
