History Funny / AssassinationClassroom

** Koro-Sensei manages to replace the students' Anti-Sensei knives with tulips, only for Kataoka to yell at them that they're the tulips that the students so diligently raised, which Koro-sensei unknowingly plucked. The scene alone adds so much humor when you see Junior High kids commanding an all-powerful being on the right way to replant the tulips while he is cowering in fear.

'''Kayano''': [[SugarWiki/MomentofAwesome I mean isn't he the most coolest teacher we ever have!!]]

-->'''Koro-sensei (currently not named yet):''' Hmm... I don't really have the kind of name you tell people. Go ahead and give me one.
-->'''Maehara:''' You sure about that?

** Koro-sensei spends the night making encyclopedia-sized travel guides for everyone. They come in with a small model building.

--> '''Koro-Sensei:''' (after the song) Now you try it!
--> '''All Students:''' ARE YOU KIDDING?!!

--> '''Kayano''': So, like, how is it supposed to attack?
--> '''Nagisa''': What do you mean?
--> '''Kayano''': Well they call her a ''Fixed Artillery'' don't they? Do you see any guns? 'Cause I sure don't.
--> '''Nagisa''': Yeah... Good point.
--> '''Ritsu''': [Unleashes four shotguns and two machine guns. Initiates assassination.]
--> '''Nagisa''': [[DangerDeadpan Nevermind!]]
--> '''Sugino''': [[PrecisionFStrike HOLY CRAP!]]

--> '''Takebayashi''': "2D is just fine. Real women don't need more dimensions than that."
--> '''Other students''' (''shocked''): "[[LampshadeHanging Takebayashi, do you seriously want that to be your first line in this manga?!]]"

** How does the class avenge Maehara from the humiliation he recieved from his ex-girlfriend and her new boyfriend? By making them go through their own HumiliationConga involving a LaxativePrank. Seeing them desperately running to the nearest toilet as the class continues to screw them over is hilarious and very satisfying.

--> ''"Even a cabaret girl would act awkwardly if she suddenly had her father as her customer, y'know?"''

* The similarities between Koro-sensei and Itona.

* The Chemistry final exam's hardest question is represented by a monster in heavy armor. The Virtuoso complains that he can't get it off...only for Okuda to ride by on the shoulder of one that had already taken off its helmet, showing that it's actually an ''adorable'' monster. The monster then strips off its armor entirely and skips off with Okuda still perched on it and the A-Class student can only stare in shock.

* Episode 16. Whilst Class E was at the end of term assembly, Irina and Korosensei were talking about the LoopholeAbuse with the home-ecs exam, then Irina asks why they can't go to the assembly and Korosensei says that Karasuma told them that they're presence would attract attention (episode 5) It rounds off with Irina calling Korosensei calamari (fried squid) and Korosensei calling her a bitch.
* [[http://www.mangahere.com/manga/ansatsu_kyoushitsu/c056/13.html "Perversion...can save the world."]]
** In the same chapter, we have [[ItMakesSenseInContext a giant rhinoceros beetle and a middle-school girl jumping on top of porno magazines]].

** And the kicker? It wasn't even necessary. Karma [[ForTheLulz just thought it would be amusing.]]

* After everything has been solved (and Koro-sensei has survived yet another assassination attempt) Koro-sensei states they are going to have fun now... only for Kiruma to point out that they are leaving the following day. Cue Koro-sensei trying to do all the usual summer things (watermelon piñata or making a sand Tokio Tower) in the next few seconds... only for Karma to shoot him. Most everyone joins in shooting their teacher.

* The entire Koro-Sensei Drawing Song. [[https://www.youtube.com/watch?v=ULWGpwuLbJ0 Sung by Jun Fukuyama (in Japanese)]] and [[https://www.youtube.com/watch?v=USGZ57ZOpC8 Sonny Strait (in English)]].

** Also, FunnyBackgroundEvent in the anime (Season 2, Episode 21): Irina is emitting hearts constantly. Then Koro-sensei ropes them in for a wedding photo - and Irina has a {{Nosebleed}}.

** After getting caught on Karma's first trap, Koro-sensei spends the whole next hour - while the teens are doing an exam - weakly punching a well. The kids shout at him for breaking their concentration.

'''Lovro''': ...[[EvenEvilHasStandards these children are ]][[EvenEvilHasStandards ''brutal''...]]

** Tadaomi quickly tears them apart and pins Irina's arm behind her back, leading her away from Nagisa.
** And in Chapter 8, there's the 30-hit combo french kiss.
** In chapter 11, there's also the scene where Koro-sensei arrives on the stage. Irina casually stands next to him and tries to stab him repeatedly, but Koro-sensei dodges each attack. Then Tadaomi once again pins her arm behind her back and leads her away before she blows their cover.
** There's also a moment where some of the girls from Class-E come up to Tadaomi and show him their bedazzled knife sheaths, asking him if they look cute. His response is to tell them to never take them out in public, even if they ''are'' cute.
* During the Kyoto field trip, it's discovered that Koro-sensei gets motion sick and is lying on a couch in their hotel feeling awful. [[HypocriticalHumor As a student is asking if Koro-sensei is feeling okay, she and other students calmly attempt to stab him in the face. Repeatedly.]]
** And he complains that he forgot his pillow at home.

** Sugaya comes back with a tattoo on his arm. It turns out to be a traditional Indian Henna tattoo, which is temporary. We quickly cut to Koro-Sensei, who was in the middle of reading a mountain of books on what to do when one's child becomes a delinquent.

* At one point Koro-sensei teaches all the students in class by moving fast enough to create tangible afterimages and using those afterimages to tutor each student. One student is worried that it would exhaust him. Koro-sensei tells the student to not worry, [[ComicallyMissingThePoint because one of his afterimages]] [[RefugeInAudacity was in charge of resting]].

* Korosensei demonstrating the effects losing a tentacle has on his speed. It starts with a few of his copies becoming kiddie versions, and eventually devolved into a family drama about a single mother.

* As a result of Class E's good results during the final exam, Korosensei has to let them shoot off three tentacles as his part of the deal. He thinks to himself that it's fine, only for Terasaka and co. to march up to him with four more exam scripts showing they all placed first in ''home economics''. Upon realizing he has to let his students shoot ''seven'' tentacles, he starts panicking like crazy!

* In chapter 59, as part of their assassination preparations, the class prepares a film for Koro-sensei... and it turns out to be his most embarrassing moments, which includes cross dressing in order to get into an "all you can eat cake" event, and using his speed in order to get free tissues so he can fry them later.

** The best one? "Can someone find a dirty old man; I wanna stick this inside his underwear!"

* Chapter 81: During the tag game, when Karasuma-sensei is drowning Bitch-sensei, her face is fucking hilarious.
** Sugaya doesn't believe Okajima when he tells him that Karasuma-sensei is going to catch him. ''[[http://www.mangahere.com/manga/ansatsu_kyoushitsu/c081/17.html Turns out he's right behind him, Spider-Man style.]]''
* The students various acts of escape in chapter 82. From bribery, to playing at Koro-Sensei's emotions.
* Chapter 83: The class pull [[Manga/SoulEater Excalibur faces]] on Koro-sensei when they thought he's an underwear thief.
** Isogai defends Koro-sensei by listing some examples of how his teacher is just a "normal pervert" which then prompted him to change his mind instantly.
* How Itona joined the Terasaka's gang is both this SugarWiki/{{Heartwarming Moment|s}}.
--> '''Itona''': Hey, Muramatsu. I don't have any money. I'll hold in my puke, so let me eat some ramen.
* Chapter 88:
** Itona builds a mini-tank with a camera to kill Koro-sensei. The boys realize that they can look under skirts of the girls with that tank instead, and the boys create an operation how to develop the perfect tank for that matter. All of them have act with ''serious faces'' and have specific roles.
** The tank is destroyed by a weasel, which got 7th place in popularity polls.
** The boys' efforts are busted by Okajima declaring out loud his intent to look under the girls' skirts by March, right as the girls are behind them. He gets chewed out for his trouble, while Itona walks away, whistling innocently.
* Chapter 89: All of the {{Code Name}}s are ridiculously [[MaliciousMisnaming funny and fitting]].
** People in the hospital reacted to the name JUSTICE!! Kimura.
** Karma: That must be rough, getting stuck with weird names
-->Everyone SpitTake.
-->Karma: What? I like my name.
** Korosensei also has a complaint about his name, Karasuma and Bitch-Sensei refuse to call him by name.

* Koro-sensei drops in from out of nowhere*\\

* Chapter 109: Karasuma manages to avoid the God of Death's "Invisible Scythe" actually a hidden gun in his finger with a little help from Koro-sensei. How does Koro-sensei maintain the illusion that Karasuma is bleeding out? By drinking tomato juice non-stop. The fight is then decided with [[GroinAttack a single punch to the God of Death's nads]].

** And the caption for the next chapter: Kiss of Death! ... Ultimate Tongue-nique Taught By a Bitch!

** When they reveal no one was in danger the whole time, and the 'bomb' they were using as a threat was actually full of bean jam as a gift from Korosensei. Nagisa being polite and apologetic is also funny.

* Chapter 175 has a minor but welcome tension reliever: After Kayano is saved, the other overjoyed students all make a mad dash to glomp her, with Hazama and Okajima respectively crawling like a spider, and ''drooling''. Poor Kayano, who barely had time to collect her thoughts, understandably freaks out, while Nagisa instead flashes a meek and embarassed smile.

** Karasuma proved himself to be not so weak after all and scared the shit out of Irina and ''Koro-sensei''. So much so that Koro-sensei prepared full body armour under the off-chance he had to stay perfectly skill for one second for Karasuma to knife him.

-->'''Lovro''': ... but I wonder if you could explain to me this business of "psyche attack".
-->'''Nagisa''': Well the idea is to throw him off guard and slow him down.
-->'''Maehara''': Oh, he likes porn. Makes no bones about where he gets it either, figure we'll use that on him.
-->[''cue flashback of Koro-Sensei passing out popsicles to Nagisa and a few other students'']
-->'''Koro-Sensei''': Look, just promise not to tell your classmates, ''alriiiiight''?
-->[''cut back to present day'']
-->'''Maehara''': He bought our silence with a round of popsicles. [''suddenly with shining red eyes''] But it's gonna take ''a lot'' more than ''that'' to keep us from spilling the beans!
-->'''Terasaka, Muramatsu, Yoshida, and Hazama''': Let's gang up and teach the perv a lesson he won't soon forget!
-->'''Nagisa''': It would ''really'' get in his head if we threatened to blackmail him. He'll be so freaked out by what we got.
-->'''Lovro''': ...these children are ''brutal''...

* In chapter 59, as part of their assassination preparations, the class prepares a film for Koro-sensei and it turns out to be his most embarrassing moments which includes cross dressing in order to get into an "all you can eat cake" event, and using his speed in order to get free tissues so he can fry them later.
** In the English dub, once Koro-sensei sees what the film is going to be, he screams a hilarious line which is funny both [[ItMakesSenseInContext in-context and out]].

-->'''Mimura (voice-over from video):'''... and that's not all. To truly plumb the depths of this creature's depravity, we've prepared a full hour of shocking footage.
-->'''Koro-sensei:''' '''THERE'S A WHOLE HOUR OF THIS TRA--'''
-->''*One hour later...*''
-->'''Koro-sensei:''' ''*in a raspy voice*'' No point of killing me class, I'm already dead - emotionally, intellectually, socially, dead...

* After everything has been solved (and Koro-sensei has survived yet another assassination attempt) Koro-sensei states they are going to have fun now... only for Kiruma to point out that they are leaving the following day. Cue Koro-sensei trying to do all the usual summer things (watermelon piñata and making a sand Tokio Tower) in the next few seconds... only for Karma to shoot him. Most everyone joins in shooting their teacher.

* Irina complains that Karasuma didn't invite her to the beach, and asks if he would like to be alone with her. Karasuma ignores the offer, and Takabayashi and Terasaka's gang mock her. Cue the five teens running along the beach, persecuted by an angry Bitch-sensei.

* In chapter 59, the class prepares a film for Koro-sensei and it turns out to be his most embarrassing moments which includes cross dressing in order to get into an "all you can eat cake" event, and using his speed in order to get free tissues so he can fry them later.

-->'''Koro-sensei''': '''I GAVE YOU POPSICLLLLLLLLLLLEEEEEEEEEEEEESS!!!'''

* The whole chapter 74. Highlights include:
** Koro-Sensei playing the (Incredibly bad) ShipperOnDeck for Class E.
** Koro-Sensei having an utter shit-fit when his plan to scare the kids winds up scaring ''him'', beginning with Kirara Hazama's NightmareFace. Especially when he runs into an "Eyeless monster". Better known as [[BlindingBangs Ryuunosuke Chiba]].
--->'''Chiba:''' I ''have'' eyes...
* Chapter 75: Karasuma-sensei's first weakness: [[ObliviousToLove Super dense]].
** He's also an AmazonChaser. Poor Bitch-sensei.

* The English dub of episode 22 has a funny line in regards to Okajima's antics. As everyone starts to cut loose after Nagisa's triumph, the girls start to play in the water. Okajima, being... well, [[LovableSexManiac Okajima]], ends up trying to join in.
-->'''Okajima:''' Here I come, ladies! (''[[NakedPeopleAreFunny disrobes]]'') Geronimoooooooooo!\\
'''Girls:''' [[PervertRevengeMode PERVERT]]!!\\
'''Nakamura:''' [[TeenyWeenie Oh, shrinkage]]!

** Also a FunnyBackgroundEvent, but during the ending narration for the chapter you can see Karma giving Terasaka a flying kick in the side

'''Everyone''': *reactions of shock and horror*\\

** After getting caught on Karma's first trap, Koro-sensei spends the whole next hour - while the teens are doing an exam - weakly punching. The kids shout at him for breaking their concentration.

** When Sugino is worried whether Karma will get into fights, Karma tells him not to worry - [[ComicallyMissingThePoint he makes it a policy to make all witnesses remain silent]].

** Koro-sensei spends the night making encyclopedia-sized travel guides for everyone. They come in with a small toy building.

** Koro-sensei got distracted building snacks, so he arrived late to the station.

* Koro-Sensei in general is also pretty funny.

* When Irina joins the class as a teacher, the class wonders what he looks like when he is captivated by big breasts, and were disappointed by how plain his lovesick expression was.
* When Irina tries to tell the class to call her Jelavic-Oneesama instead of Irina-sensei, the class decide to instead call her Bitch-neesan (due to Vic and Bitch sounding similar when spoken with Japanese phonology). Irina is not amused. She is certainly even less amused when they proceed to call her Bitch-sensei after she finally manages to win over their approval.
** Before she reforms, Irina had talked down to the Class E students, only having them give her ideas while she would take the kill. [[https://www.youtube.com/watch?v=S-0OJDGY1aI&app=desktop The result?]] Also counts as a SugarWiki/MomentOfAwesome.
* The first English line Irina taught to her students was "You're incredible in bed".

** Karma just beaten his opponent. What would he do? Why, torture the poor guy with mustard and wasabi, of course!

** Karasuma proved himself to be not so weak after all and scared the shit out of Irina and ''Koro-sensei''. [[spoiler: So much so that Koro-sensei prepared full body armour under the off-chance he had to stay perfectly skill for one second for Karasuma to knife him]].

** [[spoiler: He can't swim.]]

* In Chapter 60, [[spoiler: after they fail to kill Koro-sensei, Karma proceeds to bully him while he can't move at all.]]
** The best one? [[spoiler: "Can someone find a dirty old man; I wanna stick this inside his underwear!"]]

** He's also an AmazonChaser. [[spoiler: Poor Bitch-sensei.]]

* How [[spoiler: Itona]] joined the Terasaka's gang is both this SugarWiki/{{Heartwarming Moment|s}}.
--> [[spoiler: '''Itona''']]: Hey, Muramatsu. I don't have any money. I'll hold in my puke, so let me eat some ramen.

** [[spoiler:Itona]] builds a mini-tank with a camera to kill Koro-sensei. The boys realize that they can look under skirts of the girls with that tank instead, and the boys create an operation how to develop the perfect tank for that matter.

* How does Nagisa stop [[spoiler:the berserk Kayano? He hits her with a 15-hit combo kiss to [[PostKissCatatonia knock her out]]]].
** And the reactions! While everybody else is being shocked, Karma and Nakamura whip out their phones to take pictures! [[spoiler:Which they pull out in Chapter 159 to flaunt when they find out she has obligation chocolates for him.]]
** And the caption for the next chapter: [[spoiler:Kiss of Death! ... Ultimate Tongue-nique Taught By a Bitch!]]
** [[spoiler: Kayano's]] been [[http://www.mangahere.co/manga/ansatsu_kyoushitsu/c142/9.html shot through the heart]] and [[http://www.mangahere.co/manga/ansatsu_kyoushitsu/c142/10.html Nagisa's to blame]]
* In chapter 143, [[spoiler: when Nagisa and Karma get into a fight, Isogai and Maehara had to hold back Karma and Sugino had to hold back Nagisa. While Isogai and Maehara are having some trouble holding back Karma and even commenting that he's incredibly strong, Sugino had absolutely no trouble at all as he is holding Nagisa back with one arm while Nagisa is flailing his arms and legs trying to break free.]]

** As a FunnyBackgroundEvent, you can see as they go home, Karma playing on a gaming device [[spoiler:while in space]].

* Chapter 175 has a minor but welcome tension reliever: [[spoiler:After Kayano is saved, the other overjoyed students all make a mad dash to glomp her, with Hazama and Okajima respectively crawling like a spider, and ''drooling''.

--> [[spoiler:'''Kayano''': [[ACupAngst AND JUST WHAT DO YOU MEAN BY THAT?!]]]]

** Irina tries to flirt with Karasuma who is her new boss [[spoiler: and husband]] as he is about to send her on a mission. Only for him to be in Business Mode, quickly dismiss her, and suggest a replacement if she can't handle it. Cue her to lose all composure and plead she can do it like a child who was told she can't go see a movie.
* Chapter 180: Nagisa hit a massive growth spurt and became the teacher of an eager class... is what he would have liked. [[spoiler: The reality turns out that he didn't grow an inch since middle school and he wound up teaching a class of delinquents.]]

** Some of Koro-Sensei's ridiculous counterattack when being attacked. For instance in Episode 1/Chapter 1, Karasuma tries to strike Koro-Sensei with a knife and he gets his eyebrows meticulously trimmed. Koro-Sensei even mentions a fighter jet tries to shoot him down only for him to wax it.

'''Matsukata''': ''[[TheScream GYAAAAAAAAAAAAAAAAAAAAAHHHH]]!''\\

'''Matsukata''': '''[[TheScream GYAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHH]]!!!'''

* Episode 1 -Assassination Time

* Episode 1 of the anime adds a line that's a major CallForward to the nickname game from chapter 89.

* Episode 19/chapter 69
** Korosensei starts enjoying the infiltration too much, so the others yell for Nagisa to spin him around, which he does so with a staight face before Karma asks for Terasaka so he can AssShove Korosensei up his pants
