Whenever I need a serotonin cost increase , I watch David Harbour utterly lose it every time he attempt to say the " it ’s your granny " note fromStranger Things .

1.In theBarbiemovie, there’s a hilarious scene when Barbie finally agrees to be Ken’s “long-term, long-distance, low-commitment casual girlfriend.” Ken plays it cool but then excuses himself to yell “SUBLIME!” behind a wall.

Well, as it turns out,Ryan Goslingimprovised a few different versions of this line — and they all made the cast and crew (and even directorGreta Gerwig) crack up. The biggest offender? “Her milkshake brings this boy to the yard,” which had everyone, includingMargot Robbie, in fits.

2.It also looks like Ryan and Margot kept collapsing into giggles during the scene where Ken tries to kiss Barbie near the beginning of the film.

The bloopers aren’t officially released yet, but you can catch Margot laughing at “SUBLIME!” — and the kiss — here.

3.Brad Pittwas having wayyy too much fun while shootingBullet Train. He cracks up in most of the bloopers, but especially this one scene with Brian Tyree Henry.

As to why he kept laughing so much? “First of all, he’s a chump, and the chump is the most fun role to play hands down,” Pittsaidof playing the character. “Everyone here is such a high degree of talent that we had a lot of good laughs. I surely had a lot of good laughs.”

4.My personal favoriteBullet Trainblooper is from when Tangerine (Aaron Taylor-Johnson) and Lemon (Brian Tyree Henry) try to hide the fact that The Son is dead with anime glasses.

The glasses refuse to stay put on Logan Lerman’s head, and Aaron Taylor-Johnson and Brian Tyree Henry keep cracking up as they attempt to fix them — with Lerman unable to help but join in, even though his character is supposed to be dead.

You can watch the bloopers here (at 1:46 and 0:15)

5.In 2021, Jerry Seinfeld revealed that “the hardest scene to film onSeinfeldwithout laughing” was the scene in which a “library cop” interrogates him about a book he didn’t return. “It was just so ridiculous that he was interrogating me in my own apartment about a book. I just kept cracking up,” Seinfeldsaid.“So that scene that you see is made up of about eight different times we shot it. We took the pieces that worked and put it together because I messed that one up a ton.”

You can watch the full scene here:

6.In a funnyThis Is 40scene, Melissa McCarthy’s character berates and threatens Leslie Mann, Paul Rudd, and Joanne Baron.

But as an extended version of the scene that plays during the credits reveals, McCarthy said a ton of stuff that wasn’t in the final cut. And Mann and Rudd absolutely could not keep it together.

Watch the extended scene here:

7.One funny moment from Season 2 ofThe Umbrella Academyis when Luther farts in the elevator, garnering disgust from his siblings. Aidan Gallagher (who plays Five)saidfilming it was the funniest on-set moment of the season, and Tom Hopper (who plays Luther) said that David Castañeda (who plays Diego) couldn’t film it without laughing. “The elevator scene up to the tiki bar always sticks in my head. I mean, I don’t actually think we got a clean take with David.”

You can get a taste of what it was like to film the scene in one of the bloopers, where Robert Sheehan, as Klaus, did a little improv and the whole cast broke.

See a blooper of the scene here:

8.In one of Jason’s best lines onThe Good Place, the always-evil Shawn refuses to work with the group, and Jason claims that Shawn has “changed.”

But the bloopers reveal the cast could barely get through the line without laughing, and Michael Schur, the show’s creator,saidthe actors were laughing at the line “for three and a half minutes” straight. Apparently, Ted Danson laughed so hard, he cried.

9.And when Shawn finally does agree to work with them, he hilariously struggles to say it out loud to his subordinates.

As you can see, Marc Evan Jackson, who played Shawn, also had trouble getting through the line — because he kept laughing at his own attempts at gagging and struggling through the line.

See the bloopers for both scenes at 3:34 and 1:43, respectively:

10.The cast ofParks and Recreationdid lots of improv, and while a lot of it did end up in the final cut, not all of it did. Take this scene where Andy and April go to the doctor, and Andy lists a bunch of concerns he has.

In the bloopers of the scene, Andy says much more, including this great line about “wiping a marker” — it’s so funny that Aubrey Plaza, as April, has to turn away from the camera, then completely gives up at the end and laughs as the crew starts laughing, too.

Watch the blooper here:

11.Similarly, Retta couldn’t get through this scene with Ben Schwartz, who played Jean-Ralphio, where he describes what they’ll do at the club together.

12.One lastParks and Recone: There’s a funny line in a later season where Craig announces that his young friend drove him to work (despite being underage and unable to drive).

The scene was much longer in the bloopers, with the other actors goading Craig into saying the line over and over again. Except for one problem: none of them can keep a straight face.

Watch the scene here:

13.In Season 2 ofStranger Things, there’s a scene where Hopper decides to tell Mike there’s something wrong with his grandma and he needs to go home immediately, purely because he’s annoyed with Mike and El’s behavior.

The scene is funny in that we know there’s nothing wrong with Mike’s grandma and Hopper’s just being Hopper, but David Harbour seemed to find it MUCH funnier than anyone else. He could barely get out the words “It’s your grandma,” causing his young castmates to crack up too.

14.There were two more moments in Season 4 that the cast really struggled with. The first one is when Dustin lied to the cops about why they were at the lake.

Gaten Matarazzo couldn’t seem to get through the high-pitched line, especially because it looks like Caleb McLaughlin kept laughing or making him laugh every take.

15.The second is Argyle’s line, “I know a magical place that has all you need, my brave, little superpowered friend. That mind fight is on.”

Eduardo Franco, who plays Argyle, had a little trouble getting through the line, but it was Charlie Heaton who lost it every time.

You can watch both in the bloopers here (the first is at 1:35 and the second is at 3:01)

16.In another normally serious show,Better Call Saul, there’s a lighter moment in Season 2 when Saul uses Kim’s finger to brush his teeth. He then says, “Wait till you see what I floss with,” which causes Kim to laugh. Answering a fanon Twitter,the actor, Rhea Seehorn, said her laugh was real and that she laughed at the line every single take.

17.InThe Usual Suspects, the lineup scene wasmeantto be serious. “We were supposed to be very stoic, very unimpressed, unintimidated,” Kevin Pollak, who played Hockney, said. But “we would lose it over and over and over.” Pollak alsoclaimedin the DVD commentary that part of the reason they laughed was that Benicio del Toro “farted like 12 takes in a row.”

18.In an old example, Don Knotts kept laughing during this scene onThe Andy Griffith Show— theyhad to reshoot it20 times because he couldn’t keep a straight face. In the final cut, he keeps it together, but you can see Andy Griffith laughing.

You can watch the scene here:

19.On their podcastOffice Ladies, Jenna Fischer and Angela Kinseyrevealedthat John Krasinski would often break character and laugh — particularly during one episode: “The Secret.” In the episode, Michael (played by Steve Carell) knows Jim (Krasinski) has a crush on Pam and keeps trying to talk to him about it. “This whole episode, John had to do a lot of scenes with Steve and he really loses it,” Fischer said, pointing to the scene when Michael tries to talk to Jim at the venting machines while Stanley is there.

20.While you can’t see it in the final cut, he also kept laughing when Michael put his foot on Jim’s desk to ask him to lunch. “John lost it,” Fischer said. “And part of it, too, was that desk is so high and it was not easy for Steve to put his leg up there, but he was super committed to the bit. It was something he just came up with, and it made John laugh, so he just kept doing it.” Krasinski also kept laughing at the end of the episode when Carell hugged him. “John couldn’t handle it. He couldn’t handle it,” Fischer revealed.

You can watch the first scene (plus a little extra) below, or check out the full episode onPeacock(it’s Season 2, Episode 13):

21.Ed Helms had the same problem in a different episode ofThe Office.When Kevin is sitting on Michael’s lap when he’s playing Santa, Helms keeps laughing, and in the final cut, he said, he actually ended upduckingbehind a plant to hide it. You don’t see the plant, but you can see him smile, and then, in the next wide shot, he’s not there anymore. This was apparently also the 30th take because the cast kept laughing.

22.One of the most well-known scenes onFriendsis the “Pivot!” couch scene. Well, it turns out that the actors found it just as funny.

In bloopers for the scene, all three actors keep laughing as they try to do the scene, with David Schwimmer imitating his “Pivot” line and collapsing in stitches.

23.In the scene where Ross plays bagpipes for everyone inFriends, you can actually see Jennifer Aniston breaking character as Phoebe starts singing.

But in the bloopers,you can seeit wasn’t just Jen — they all burst out laughing and then struggled to keep it together.

24.One lastFriendsone — in the scene where Ross and Rachel’s sex tape is discovered, when Rachel moves to destroy the tape, it turns out everyone was struggling to get through the scene.

“Every time I went to take the tape and step my foot on it, all of your reactions were like, ‘No, no, no, no, no!’ That took us about 45 minutes, just that piece to shoot, because the laughing, we couldn’t stop it,” AnnistontoldMarie Claire.

You can watch the blooper at 7:11 here.

25.And finally, this isn’t a blooper — and the laughterwasin the script — but the degree to which Rue McClanahan and Bea Arthur utterly lose it while Betty White is explaining the “herring war” onThe Golden Girlshas oftenbeen citedas one of the series' most hilarious examples of Betty White cracking everyone else up.
