History Funny / OnePunchMan

* Saitama tries to help Flash free his trapped arm by clearing away the rubble around it, among which is a small cube he tosses away, landing in front of Manako, where it cracks the earth from the impact. Manako tries to pull the cube out, but can't budge it.

* Neo Leader, Zaedats, shows off his battle suit which he spent 200 billion yen on and boasts that if the other suits are like "cars", his is a "space shuttle". He then gets defeated by a Demon-Level threat '''[[EpicFail off-screen!]]'''

-->[[ComicallyMissingThePoint Saitama: If that's no good, how about I give you my kitchen knife? It's stainless.]]

* Sonic cooks a monster cell before eating it, because it is not healthy to eat meat raw. He even adds vegetable garnish and a bottle of wine and sits down as if at a restaurant. It [[JustForPun gives him the]] [[ToiletHumor runs]] instead.

* The first opening, [[https://www.youtube.com/watch?v=atxYe-nOa9w THE HERO!!! ~Set Fire to the Furious Fist~]] ends with the sunlight shining off Saitama's bald head

* The first opening(The Hero) ends with the sunlight shining off Saitama's bald head

* Tatsumaki's anime-only segment in Episode 10 can be considered this. A giant Godzilla-like monster starts attacking a mountain range and Tatsumaki gets airlifted in to fight him. Just as she lands, however, she gets a phone call from the Hero Association calling her back, and she starts arguing with them, completely ignoring the monster. He starts speaking over her on the phone, and she gets angry and insults him and his chin before killing him. Also doubles as a SugarWiki/MomentOfAwesome.
** One exchange implies that the monster [[TalkingIsAFreeAction was waiting for her]] [[PoliteVillainsRudeHeroes to get off the phone before taking a swing at her]].
--->'''Tornado''': HEY! Shut your snout! Can't you see I'm talking on the phone here?!
--->'''Ancient King''': ''[growls]''
--->'''Tornado''': ''[hangs up]'' Ugh, I am so tired of this. I mean, who does he think he is? Annoying...
--->'''Ancient King''': Are you done?
** There's also the way that Tornado kills the Ancient King. When the monster [[TemptingFate claims that the only thing that's capable of destroying him is]] "[[ExactWords a giant meteor]]", she decides to take him up on that challenge by doing exactly that.
--->''(Tornado pulls an asteroid out of space and drops it down to Earth. Cue a large crater containing [[{{Gorn}} what's left of Ancient King]].)''
--->'''Tornado''': How about another 300 million year nap?

* Speaking of Tatsumaki in ep 10, there's also her {{Art Shift}}s to ONE's webcomic style. Turns out seeing them animated is just what's needed to make them utterly hilarious.

** Genos rushing off to grab duct tape when given a choice to pay for or repair Flashy Flash's sword.

* Saitama's lackadaisical demeanour as debris from the meteor engulfs the city in chaos. [[http://mangafox.me/manga/onepunch_man/v04/c021.4/46.html]]

* When Sonic and Pri-Pri-Prisoner meet, Pri-Pri-Prisoner [[PrisonRape tells him why he was keeping himself in prison]]. Sonic remarks that he should stay in jail. Also when Pri goes [[FullFrontalAssault "Angel Style"]] and declares that no one has seen him in that form and lived, [[ScrewThisImOuttaHere Sonic thinks that he'd better go home.]]

** "Angel Style" itself in the anime, just from how Pri-Pri-Prisoner visually evokes ''Manga/SailorMoon'' while doing it.

* During his fight with Boros, Saitama punches Boros across the city-sized spaceship they were on as soon as the alien stops talking. Boros ''survived'' a full on, serious attack from Saitama, but at the cost of his armor. The clincher? The armor acted as a PowerLimiter.
-->'''Boros:''' This set of armor, which was used to seal in my immeasurable, irresistable power, has now been broken.\\

* After the invasion is over, Tatsumaki starts chewing out Saitama for rushing ahead into the spaceship and not respecting his lowly station as a B-Ranked hero, but most importantly calling him a [[BerserkButton "baldy"]] over and over again. Saitama then instructs Genos to tell her off. Genos tells her to shut up or he'll crush her. [[GilliganCut Cue Genos getting smashed into a giant pile of rubble.]]

* In Chapter 47, Saitama meeting Tank-Top Master in the hospital when he joins in on Saitama and License-less Rider's conversation.

'''License-less Rider''': He's the S-Class hero, Tank-Top Master.\\

*** The anime makes the OhCrap moment even funnier by having Garou's sweat go ''upwards'' when realising his attack just had no effect.

* Saitama asking the half blown apart Monster Bakuzen's corpse who he was before quickly saying "meh forget it."

* Genos has already shown to be distrusting towards the Hero Association, has been invited to join Neo Heroes and finally tells Saitama about it and asks if he would also like to transfer to Neo Heroes. Naturally this is his response:

* Saitama's plan to get Flashy Flash a new sword is to let Sonic attack him, defeat him and confiscate his dangerous weapon as the good hero he is. Naturally Genos is impressed at this and writes it down.

* While talking to the other 3 A-Class heroes about getting recruited by a certain organization, Saitama himself gets recruited... by the "Hero Name Victims Association" which is comprised of heroes with terrible names. They want Saitama as their executive due to him having the most terrible name among the A-Class. Saitama legitimately thinks they are the association who will cause a major power shake up and bides his time to tell Genos about it.

* In the first episode, the giant "strongest man in the world" fight. Saitama jumps onto his shoulder, and the giant's brother on his other shoulder commands him to "squash the guy on your shoulder". The giant crushes his brother. His reaction at realizing he just killed his brother [[BlackComedy is priceless.]]
-->'''Giant:''' ''[beat]'' '''NIIIIII-SAAAAAN!!!''' / (Dub) '''BROTHER, [[BigNo NOOOOOOOO!!!!]]'''

* Saitama actually joined the Hero Name Victims Association as their leader no less and participates in their protest.

* The beginning of the OVA has Sonic fighting a monster that looks like the Sea King and the battle about to end with a GroinAttack that causes the scene to shift and reveal that it was a nightmare...that Sonic had of Saitama. Considering how different Saitama looks from the nightmare Sonic fought, it's funny that [[IdiotHero he traumatized him despite his lack of effort in trying to fight him.]]

* When Saitama encounters a B-Class criminal known as Men's Esthetician Man, despite the criminal remembering Saitama for beating him, Saitama [[ButForMeItWasTuesday doesn't remember him]]. When the criminal mentions that he's been trying to find him, Saitama jumps to the conclusion that he's the stalker who stole his French fry and turns his face serious before one punching him into a wall. The criminal has a OhCrap reaction before it cuts to black.

** After a week the group has pooled funds through part-time jobs. And then Fubuki walks in having snagged 2 million yen by herself. This leads to the group thinking she was getting it through...illicit methods. Turns out she was out bounty hunting, which was what she actually meant when talking about using flyers to get money quickly.

* Neo Leader, Zaedats, shows off his battle suit which he spent 200 billion yen on and boasts if the other suits are like "cars", his is a "space shuttle". He then gets defeated by a Demon-Level threat '''[[EpicFail off-screen!]]'''

* Atomic Samurai's ultimatum following this takes things a step further. By getting King to use a katana to cut an apple, he can understand what kind of life he's lead. King spends 2 minutes and 40 seconds just sitting there staring at the apple before putting the sword down, too nervous to actually do anything, then walks away. Atomic Samurai becomes convinced that King [[ImplausibleFencingPowers cut the apple so fast that not only did he not see it, but the sword passed through the apple without harming it]].

* Nyan using his powers to slip into small places to come in and come out of Drive Knight's armor, resulting in his opponent hitting himself, is something coming straight up of a ''WesternAnimation/LooneyTunes'' cartoon.

** When Fubuki first introduces herself, she asks if Saitama knows who the Blizzard Group is. After a brief moment of thinking. he responds with the goofiest smile on his face saying he has absolutely no idea who they are. When she explains she's the 1st Rank Hero in B Class he congratulates her and simply asks "So?" with the same goofy ass smile on his face!

* After passing the hero exam, Saitama meets teacher Sneck, who, as you might expect, is a very SmugSnake. After hearing that Saitama and Genos are MUCH stronger than him, he goes off to disprove this by [[BullyingADragon attacking Saitama]] while the latter is walking about, deep in contemplation. We see him throw one punch about to land... and [[GilliganCut the next frame]] is [[CurbStompBattle him buried headfirst in the ground, with Saitama carrying on as if nothing happened]].

* Saitama watches television and sees the Paradisers cause chaos, lead by a B-class criminal who has a reputation as a OneManArmy? Boring. The local law enforcement can handle this. They're all... [[BerserkButton bald?]] [[SeriousBusiness Unacceptable!]] They stole his looks, and he'll be treated as a villain because of them!

** Tank-Top Tiger has the nerve to call Saitama "[[BaldnessAngst cueball]]", clearly scoring an emotional crit on Saitama.

* Tank-Top Tiger has the nerve to call Saitama "cueball", clearly scoring an emotional crit on Saitama.

* During Saitama and Genos' training match, it looks like Saitama is actually going to get serious and completely rock Genos' face off... only to end his punch about an inch away and then flicking Genos in the forehead. He then does the goofiest little march away after declaring that they're going out for some udon while the panel cuts to show that the ''blowback'' from Saitama's punch decimated the entire mountain range behind Genos.

* Nyan using his powers to slip into small places to come in and come out of Drive Knight's armor, resulting in his opponent hitting himself is something coming straight up of a ''WesternAnimation/LooneyTunes'' cartoon.
* Saitama is bored while riding a mine cart and tells the monster with them he should at least act like a tour guide. The monster nervously starts to act like one before Flashy Flash tells him to ignore him.

* During the fight between Tatsumaki and Psykorochi, Tatsumaki manages to utterly fluster the monster by managing to get inside her body from the ground while she was distracted and travel all the way up to main body...and ends up [[ThanksForTheMammary pushing out against Psykorochi's boob while commenting on how surprised she is it's hollow]].

* Bang's fight with Fuhrer Ugly. Bang has the upper hand, successfully creating holes in the other's body. Then Homeless Emperor shoots out his energy balls to his direction. [[OhCrap Bang unsuccessfully calls time out and gets caught in the explosion]]

* The reason why Saitama is late: He was buried with Lightspeed Flash when Tatsumaki pulled the MA headquarters to the surface. Lightspeed Flash says that something will break and our hero thought it was his arm that was pinned under the rocks, so he had to manually move the rocks in order to remove it. But what Lightspeed Flash is refering to is his sword, which promptly breaks after Saitama accidentally breaks it after pulling it out in frustruation.

** What makes it even funnier is how it happened. Saitama punched Flash's head, which hits the back of the sword and it breaks in two. Flash's expression sells it even more.

* During the fight between Tatsumaki and Psykorochi, Tatsumaki manages to utterly fluster the monster by managing to get inside her body from the ground while she was distracted and travel all the way up to main body...and ended up [[ThanksForTheMammary pushing out against Psykorochi's boob while commenting on how surprised she was it's hollow]].
