WHEN PARTIES GO HORRIBLY WRONG! 

Love how Simon complained about the first one being too mild and then the rest were literally all massacres

13:59 We all saw Harry laughing but I am surprised that JJ didn’t say anything.

The face Harry made when he clocked the guys last name 😂 13:49

Simon looked devastated watching this after the first one P.S. Harry’s face at 13:47 when he said that name 😂

Parties that went wrong : when Phil arrived at Josh’s birthday party in the sidemen video 😂😂

"I went to a party and I slept with none of them" *Typical JJ Failure*

harry trying so hard to not laugh at the woman's name lmao 13:58

Bloody hell this is dark

harry's face at 13:47 💀

13:47 i love Harry's reaction when he heard the name😂😂😂😂

13:48 The smile in Harry's face 😂

"Marinate the chicken and choose the one to eat" ~ JJ 2021 It's literally a new quote every week

I thought they were gonna say "Oops! Silly guy! He's sleeping with his face in dog crap!" But they were like "a guy didn't like these people very much, so he shot everyone and lit the house on fire"

Simon looks like he's having a crisis throughout the entire video 😂😂😂😂😂

13:46 HARRY CLOCKED IT AS WELL AHAHAHAHA WHY DID JJ NOT REACT TO IT 😂😂😂😂

13:47 Harry’s face😭😭

13:52 this man knew what he was smiling for

JJ: It's all about being able to marinate a chicken and pick who you actually want to eat. Me watching the video: Seems about right. Is it really a sidemen video without JJ doing his thing?

13:48 harry was waiting for jj to react, 14:01 harry failed to keep it in

13:46 look at how Harry reacts to her name, he’s still a kid at heart, bless him

At the retirement party of my aunt, a doctor that worked with her for years (maybe decades) hugged her so hard and for so long, jokingly, that he broke her spine. He himself diagnosed her with osteoporosis only months before. She didn’t have spinal damage, but he damaged some nerves. She loves him still btw. 👍 Great party

That last second switch up of KSI talking about his party experience saved him from sleeping on the couch for a week 😂

13:48 Harry hears the word and starts laughing 😂😂😂 what a guy😂😂💯🙏🏻

well... this wasn't as fun as I thought it would be 😅

I swear JJ can change the emotion of an entire video in under 10 seconds 😂😂😂

13:46 harry trying not to laugh is so jokes

I’ve been crying all day from uni stress and decided to watch this to cheer me up… didn’t go to plan

JJ: I think the only thing he should do is a angry tweet 🤣

Simon's angry about the first one, but at least it was the only actual big party that went in the intended direction.

I was 12 when the Covina one happened, and one of my good friends in little league lost both his parents in it. Everyone in the league was devastated and we had a memorial at the park for him

People who didn't get invited to these parties and were angry earlier would thank God everyday from that day forth

All of them: “I didn’t expect it to be about deadly parties” The channel’s name: “They will Kill You”

This sidemen Sunday (main sidemen channel) was one of the best. Have been watching for 7 years now never disappoints(first started watching ksi)

i love how frequent the sidemenreacts videos are. always so entertaining as well

13:47, Harry's face when the narrator says the 'C' word is absolutely priceless😂😂! It's funny how none of the other lads noticed it😂😂

Harry laughing at the number one entry was brilliant!🤣

Daily reminder that you are amazing and loved 😊

I'm shock that the club party incident that was located in the Philippines didn't make it through this video. It was a pre-graduation celebration. Bunch of friends decided to rent a whole club for their college celebration, and in the middle of the celebration, a fire broke out and spreads quickly. Because of panic, people ran to the door, pushing it open but didn't budge because the door was built one way. It was push if you're going in the club, and pull if you want to go out. Students ran towards the door, hoping to save themselves, but they were trapped inside because it was pull door... Those people outside the club tried to open the door but they can't open it because the students inside the club are pushing the door instead of pulling it. Due to the accident that killed a lot of graduating students, the club shuts its business down. However, people said that even though that the club is fully closed, bystanders can still hear the screams of the students that died in the club when the clock strikes at the exact time of the accident. Since then, a famous belief came in. "If you're a graduating student, you should be extra careful because accidents will come to you"

I'm new to sidemen & have only been watching for less than a month (seen around 20 different videos). This is easily the quietest I've ever seen a group of you😂🤣

the one time JJ pulls a good intro he doggs every other sidemen channel you can't write you lot I love it 🤣🤣

That guy: dies after being thrown in the air (rip) Harry: totally fine after fallen of his roof twice

13:45 Harry can't stop laughing but can't say anything😂😂😂😂

I'm sorry but it's always funny when a video turns out to be grim their reactions are hilarious 🤣🤣

Legends say Simon is still angry about the first one

This really took a turn from the first one LOL

I want these man to React most disrespectful drill lyrics by hip hop daily 😂

Love how only Harry caught on to the last one LOL i was like yoo what did he say, what was his name? Jean what?

Lmao Simon looked so scared during this video 😭😂

13:49 Harry’s face after hearing the name 😂😂😂

I thought this was gonna be comedic party gone wrong moments 😂😂

This was a lovely start to the day boys. Thanks..

13:49 Harry’s face had me dying.

The way JJ said Van Persia brought back so many memories wow Old KSI will never be topped

That last sidemen Sunday was so good lol thanks boys

I thought this was gonna be a compilation of parties going wrong like someone getting hit in the balls etc

Why Harry is so surprise about the party that simon gone 🤣

3:17 I just clocked that the man looks like big shaq

I think this was a lot more depressing than they ever thought it was gonna be 🤣🤣 sheeeeesh

Rah, that call between the survivor and the emergency services was deep. I had to skip past it. This is a mad video ya know.

Sidemen really out here thought that Project X donnie is one of the worst parties ever 😂

"It's all about being able to marinate the chicken and then pick which one you want" 😂💀😂💀😂💀😂💀😂💀

This channel almost as good as a fresh sunday church session

You can Never go wrong with a sideman video🔥🔥

me(sees the title): ahh video about phill at josh's party😂

Harry: "These parties are sh!t" 😂😂

Look at Harry’s face at 13:47 😂😂😂😂

Harry: ohhhh the bloody guns again 😂😂😂

I just love how the background music is unnecessarily scary LMAO

13:49 Harry has me cryingggg 😂😂😂

I agree with JJ at 6:14. The US needs to institute a federal firearm licensing system so as to not only decrease shootings, but even prevent them in advance.

Simon: shut down by the police Every 15-19 year old in London: ain’t that how they meant to end?

harrys face at the last one whenever they stated the ex wifes name killed me xD

When JJ in the thumbnail guaranteed JJ in the video

Channel name "they will kill you" Sidemen saying we didn't expected that from this video

What an outrageous list! Nearly all of them involve death except the first one some people stood atop some house boats. 🙈😂

🤣 I'm surprised JJ didn't react with the name. Harry was waiting for his reaction

Harry acting as if he hasn't been to any party's at 7am🔑

Thought I'd watch a funny video and sleep calmly, seeing the title.Well, that didn't work out. Rip dreams

imagine being invited to a party

13:46 Harry was waiting for JJ to say something, he's creasing!

LOve how harry tries to keep in laugh

Well, this has made my day more...... interesting.

Funny thing is Simon is confused about the first one its because he wasn't born between the mobile phone tablets and tv parenting era to them that 1st one was describing a horror story

13:47 and 13:59-14:11 harry's career flashed before his eyes 😂

After the 1st one.. Simon: why is there a skull? Me: you're in for a treat

Project X was actually based off of the Aussie legend called Corey Worthington, search up the interview its basically like what project x used at the end of the movie

Went to a bachelor party where the groom to be died from a heart attack during the festivities. R.I.P my G

the elite trio

"what a lovley start to the day" 😂

This guy has muscles as strong as rocks but his heart as soft as ravine clay!! Those tears conveyed something different !!!

Harrys face at 13:45 😂😂

no one clocked how mad simon's "it was a boy at least line was" 😂💀

From a floating tv to massacres and murders 0-100 real quick

How did JJ not get 13:47, well atleast harry did, did y'all too? 😂

Still, America insists possession of a weapon is fine.

harry was trying not to laugh at the last name, that was funny

Parties that went wrong: $20,000 vs $200 birthday party 😂😂

I just want to point out that the footage shown for the gender reveal explosion/fire is actually from arizona that happened almost 3 years ago, and not the California one.

Well… that was darker than blacking out

They should've add the picture of Simon and JJ after sideman pub golf on that couch instead of that pic on the stairs🤣
