The chapter where Mitsuhashi picks up the little foreign girl, which has gems such as the little girl imitating Mitsuhashi's Bishie Sparkle and Mitsuhashi's justification for it not being a kidnapping.
Mitsuhashi:I caught her off the streets!
Itou:She's not a dog or a monkey, you don't catch her!
Mitsuhashi then teaches the girl how to refer to him and Itou.
Mitsuhashi got arrested by the police for kidnapping the little foreign girl. Then the parents of the girl arrived... And berated the cops: they were black-skinned Americans, and so the girl the cops were supposed to rescue, while the one picked up by Mitsuhashi was a blonde half-Japanese half-Caucasian.
In the end, the little girl's identity is revealed: she's Serika, Mitsuhashi's half-American cousin, visiting with her mother (Mitsuhashi's maternal aunt, who married a blond American). Mitsuhashi was not amused. Itou even less.
And the reason Mitsuhashi picked her up? A teacher had threatened to shave his head if he returned to school blonde, and Mitsuhashi wanted to pass himself for half-American, with the girl assuming the part of his little sister. It worked.
Imai accidentally hits a cop in the face, Mitsuhashi, Itou and Tanigawa all ask him to turn himself in and beg for forgiveness, when he freaks out thinking of the trouble he will get into and knocks the officer's partner into a trash can running away. Hilarity Ensues.
Mitsuhashi trying to teach Itou's cousin how to defend himself from bullies, involving such things as peeling an onion to prove Itou that men could cry too and accidentally picking a fight with Kagawa-san.
Sagawa summoningMitsuhashi and Itou to fight off a group of bullies from Akehisa. Made even funnier by the head delinquent asking him if he thought he could scare them by saying their names before Itou walked to the scene and Mitsuhashi literally jumped out of nowhere. For obvious reasons, very few people dared to pick a fight with him after that.
During his manga debut, Imai declared he'd applaud Mitsuhashi if he managed to land a punch on him. Mitsuhashi of course lands that punch... And demands his applause. And Imai actually does it!
There's a stray dog who can perform tricks. Just one problem: "chin chin" is both the name of a dog trick and Japanese slang for dick, and when you try and make him perform that trick guess where it'll grab?
Mitsuhashi and The Thing That Goes Doink. He tricks Itou and Ryou into getting hit on the head by it, then tries it on Kurosaki, who dodges, brags that nobody would fall for it... And gets slapped on the chin when the thing is filled with water again.
In one story arc, the Akasaka's dojo (represented by Itou, Mitsuhashi, Imai, Ryou and Tanigawa) lost a match against another dojo due the opponents cheating and Mitsuhashi going overboard (he destroyed the entire enemy team by beating them with the tatami, and the rules stated they were to fight bare-handed), and, due the stipulations, was supposed to close. How did Mitsuhashi solve the situation? The Exact Words were that the losing dojo was to lower their sign, and Mitsuhashi had the sign hung near the ground.
In the manga Imai, Tanigawa and other Beni High students played a terrifying prank on Mitsuhashi, leaving him frozen in shock for a whole night. That event generated a series of these.
Mitsuhashi's Imagine Spot of what he'd do to Imai and his accomplices. It includes Mitsuhashi setting one of their homes on fire, and ends with Mitsuhashi discarding the plan because it's not epic enough!
Imai's epic Oh Crap! moment when he sees Itou trying to convince Mitsuhashi to let him live only to back down in terror.
It started with Mitsuhashi almost throwing Imai under a car and almost hitting him with a falling flowerpot, and getting him in trouble with a policeman and Kagawa-san, before beating up everyone involved but Imai and Tanigawa.
Then he lured Imai in an abandoned building and locked him in a room, with only a window to exit from. But Mitsuhashi accidentally locked himself in... Except he didn't: he was just making Imai believe it.
With the situation he had created, Mitsuhashi tricked Imai into doing a lot of embarassing things, like confessing he had never kissed a girl, eating a banana peel, weed, eggshells and his own shoe (he failed this because it stank too much), and drinking his own pee (the only reason Imai didn't actually do it was that he hadn't any to do).
Then he gave Imai an i-beam with a wire and a hook attached to try and recover a rope to use to escape. Imai had taken the rope with the hook... At which point Mitsuhashi exited the building and cut the wire, and gave an Evil Laugh to drive home the fact he had tricked Imai to easily.
What about Tanigawa? Mitsuhashi was doing him the very same thing in the very same building, only on the other side.
Oh, and Mitsuhashi took notes of what Imai and Tanigawa did under that experience, and spread the knowledge.
After taking over Akehisa, Suenaga sent his men to Nan High to demand a compensation of one million yen... Plus 3,000 yen for the consumption tax.
Itou's reply? To do the math: a 3% consumption tax on a million yen would have been 30,000, not 3,000. Then Mitsuhashi mocked them... And got the consumption tax even wronger.
The flashback with Kimimura's Origin Story, including him being nicknamedFundoshiMask, going from being his school's terror to becoming the local Butt Monkey, just for repeatedly trying to pick a fight with pre-delinquent Mitsuhashi and not realizing when it was time to quit.
Upon moving to Chiba, Kimimura tracked Mitsuhashi down to Nan High. He was terrified at the mere sight of the heads... And had an epic Oh Crap! when he asked Riko to bring him Mitsuhashi and she called one of the heads.
When it was finally clear he had issues with Mitsuhashi, he couldn't remember him... So he told him there had been a mistake and sent him to Itou. Itou beat him up in self-defence before Kimimura called him Mitsuhashi, and he explained the mistake.
Kimimura had a plan: faking having forgiven Mitsuhashi and shake hands with him while wearing nails on the inside of his fingers, then club him into submission as he was pained. Not only he got punched out, but he wounded himself when he clenched his fist to swear he would make Mitsuhashi remember.
Kimimura's desperate attempts at making Mitsuhashi remember got him beat up again and again, until he was bandaged in a way that made him look like he was wearing a fundoshi as a mask (what had prompted Mitsuhashi to call him Fundoshi Mask)... At which point Mitsuhashi finally remembered. Of the Fundoshi Mask, of course: he still had no idea of who Kimimura was. And made him a Butt Monkey even in Chiba.
Kimimura was happy... But after a while he realized he had forgot taking his revenge. Cue him trying again... Only to discover that Mitsuhashi had forgot about him again, and couldn't recall of him even with the fundoshi mask.
The creepy chemistry teacher of Nan High aspired to properly educate his students, but lacked the strength to stand up to them... So he hired a gigantic former Yakuza as lab assistant. Not even throwing coconuts at him could stop him.
When the teacher started having his Yakuza shave the boys' heads and cutting the girls' hair, Mitsuhashi entered in action. How did he neutralize the enemy? He talked the Yakuza into taking the students' side. Cue the chemistry teacher being so shaved he looked like The Greys...
This dialogue between Riko and two Hokunei punks.
Punk #1: "Are you Mitsuhashi's woman?"
Punk #2: "You know about him, right?"
Riko: "I don't know."
Punk #1: "I'll beat you up if you lie to me any more! I know you're his girl-"
At one point in the Hokunei arc, Nakano decides to enter the frame, and, upon being asked by a Mook if he has a grudge against Hokunei he replies he has none, and continues with: "But that idiot [Itou] is mad now. Which means you must be real baddies. I shall punish you evildoers!"
At the start of the arc, Nakano played the part of the Only Sane Man to Mitsuhashi, Itou, Imai and Tanigawa by trying to stop their impending fight.
Mitsuhashi and Imai's reaction to the discovery that Itou is rich.
The chapter where Kyouko visited Itou's home. Between being nervous by herself and the sight of Itou's home, she was so nervous she mistook Mitsuhashi for Itou's father.
The hilarity continued, and the chapter ended with Mitsuhashi stealing Itou's koi fish to eat them.
Riko's Imagine Spot of Mitsuhashi working as an insurance agent, a construction worker, a cook in a restaurant, and a Yakuza.
Takasaki's initial attempts at defeating Mitsuhashi.
After realizing Mitsuhashi was on the roof of the school, he went there, imagining a typical gang hangout... And found Mitsuhashi and Itou settling a dispute in a badminton match, with Riko and Yuuichi as referees.
After the match ended, Takasaki went to fight on Mitsuhashi. After declaring he has better looks, Mitsuhashi told Itou, Riko and Yuuichi to leave, then told Takasaki to wait for a minute... And locked him on the roof.
At P.E. there is Judo, Takasaki's speciality (he's a black belt). As opponent, Takasaki chooses Mitsuhashi... Who is caught painting his white belt black.
Before sparring, Mitsuhashi and Takasaki are warning each other of their own prowess (Mitsuhashi is obviously lying badly), when Mitsuhashi declares: "You... Sure have short legs".
Takasaki won handily in their spar, thanks to his superior skills and Mitsuhashi having no idea of how to perform a strangling move in Judo. So he tried to have a rematch... And glued his shoes to the wooded platform beforehand. Takasaki still managed to lift him, platform and all.
When a group of Tokyo delinquents show up to try and pick a fight with Mitsuhashi and Itou, they torture Takasaki to find out where they usually are. So Takasaki gives them directions... For Akehisa. With which they had already picked a fight.
Mitsuhashi temporarily taking over the Gardening Club.
In one occasion, Imai was arguing with Mitsuhashi and Itou when, swinging an arm, he knocked out a cop. Hilarity Ensues during his escape, especially after the Nan duo scared him with what they thought what would happens after the arrest.
In the end the cops don't arrest him for two reasons: they had heard of his fame as a brainless moron, and his attempt to escape had just got him ran over by a car twice.
One of the teachers' reaction to run into Mitsuhashi on his day off: "Uwoh! I ran into a boss monster without the proper gear!"
Mitsuhashi's first cold ever. Plus, the confirmation Imai is an idiot: he was the only one who didn't get a cold from him.
Mitsuhashi versus the pickpocket. Including the bit where they stole a bag of white powder (actually flour, but you can guess what they believed it was) from the Yakuza.
Mitsuhashi's stint as Warrior Poet. It all started from this, and, Mitsuhashi being Mitsuhashi...
The exaggerate description of Saipan's criminals that Mitsuhashi's classmates gave him.
Also, Itou telling Riko of how he talked with Kyouko about his travel to Saipan, and, blushing, ends with "And that's why I am the luckiest man alive!"... To Takasaki.
Mitsuhashi convincing himself that airplanes are actually cable cars.
Imai getting tan lines... In the form of seashells on his breast and sunglasses around his eyes, thanks to Itou and Mitsuhashi.
Mitsuhashi's attempt at comforting Tanigawa for being less manly than Jun and unable to go to a date with the college student Minako: he praises him for being compact and saving energy, and offers him a pair of theatre binoculars to spy on Jun and Minako.
Mitsuhashi mistaking two tourists for Riko and Kyouko. And tricking Itou in doing the same.
Mitsuhashi the shark.
Mitsuhashi's reaction to ending on a deserted island? He declares it his property and country, of course.
Nemoto's indirect attempts at befriending Mitsuhashi, ending when he realized he looked like a stalker.
The direct attempt too.
Nemoto: "I've been pestering you, because I'm really interested in your lifestyle... I'd like to reshape myself. That's why I've been following you around, I... Um... Can I be your buddy?"
Also, Nemoto verifying if his face was that scary: he smiled in a mirror... And jumped away in terror. Yes, his face was that scary, especially when he smiled.
Feeling guilty for having caused him trouble, Mitsuhashi decided to help a Beni High student from the shadows. The moment Mitsuhashi gets distracted, the Beni High student manages to get beaten up by none other than the amazing Fundoshi Mask.
The great battle between Mitsuhashi and Imai to discover the latter's treasure: hair restorers. That he had bought because of a scam.
Also, Itou and Mitsuhashi's Imagine Spot of Imai as the Bald Banchou.
Mitsuhashi getting fooled in believing he was going to be bald too.
Smoking Thief: "Officer, I'd like to start a new life."
Police officer: "You do that."
Imai had declared he'd enter college, but, once he tried the mock tests, discovered he had no way to succeed. What did he do? He went to the nearest college, entered the gate and declared success.
When she changed schools and enrolled at Nan High, Riko claimed it was because she was bullied.
In an early chapter, Riko saved Kyouko by two molesters, right before Itou could show up, and he felt indebted.
Itou: "Thank you, Riko-chan, I'm in your debt. I'll do whatever you ask me to!"
Riko: "Really?! Spin three times and bark!"
Itou proceeds to do just that.
Epic moment. An altercation between some students from Nan and Beni High has escalated, and Itou and Imai are about to show off... And then Imai is ran over by Mitsuhashi and Yuuichi riding the latter's out-of-control bike.
Hospital doctor who has to re-bandage Imai's broken pinky: "HOW COULD YOU DO THAT?!"
Imai: "I thought it could be healed by my manliness."
Itou hiding behind other people with his spiky hair popping out from behind them.
Mitsuhashi and Itou's disbelief at Imai's apparently finding a girlfriend in Yukari Sukiyama. That and Mitsuhashi's reaction at Imai saying that their quarrel was in the past (and Itou and Riko tormenting him by repeating it).
The picture of a younger Imai with a shaved head. It's so fun that Mitsuhashi and Itou laugh until they have stomach pain. Then they calm themselves... And starts laughing again as soon as Mitsuhashi tries to make peace and tell him he has a better hairdo than in the picture, and have to recite math formulas and history facts to stop again.
The brief arc about Imai's birthday. All of it. Especially when Imai gets pissed at his family and his neighbours coming over to see Riko, mistaken for his girlfriend, and Imai says so and that Mitsuhashi is his underling.
The alliance between Fundoshi Mask and the even more pathetic Takeda.
Mitsuhashi hiding behind Riko when attacked by a girl.
During the Hokunei arc, Mitsuhashi and Itou found themselves hunted down by that Knife Nut of Yanagi. Their counter? Wearing armour.
Later the police interrogates them on their intentions. These being Mitsuhashi and Itou, they declare themselves respectively a Restless Armor (and Mitsuhashi complains when the cop doesn't get the reference) and an Ochimusha (a samurai who lost a battle). Between Itou's face and having his hair down when he said it, Mitsuhashi and the cop laughed themselves silly, and they were let go (without armor, apparently: they stop wearing it).
The first encounter between Mitsuhashi and Takasaki: Takasaki approached him from behind to confront him about cheating at a race and put a hand on his shoulder, and Mitsuhashi punched him out without even looking and covered him with leaves to hide what he had just done. That's amusing, but not really worth of this page. Itou, Riko and Kyouko leaving because it's a common occurrence is.
This gem from Takasaki's introduction arc:
Police officer: "Aren't you the guys who broke into Kitagawa's residence? The trio with the blond and spiky hair!"
Mitsuhashi dressing as Robin Hood and shooting Tanigawa with a toy arrow when he tries to tell Imai that Ryouko is in love with him.
Later Tanigawa did it anyway, in spite of Mitsuhashi shooting him four times and then hitting him with the bow.
How does the arc ends? Easy: Imai didn't show up at his date with Ryouko because without him Tanigawa is bored to the point of crying before a punk (who ended up finding him a date), and one of their classmates jumped at the wrong conclusion and told Imai. Hilarity Ensued.
Takasaki's accidental stint peeping on Itou and Kyouko's date.
Ryou found himself with a female fan who goes at grade school... So went to Mitsuhashi for help to dump her. Hilarity Ensues.
End result? They accidentally dumped her on Takasaki. Poor Takasaki...
Mitsuhashi and the Karate Club: upon meeting them he dared one of their members to break two tiles, and when he did he challenged him with four... Only to take them away (because he's an ecologist and those tiles could be used for other purposes, he said) and let the karateka chop himself in the groin.
Mitsuhashi and Itou talking with a karate master:
Karate master: "What are you fighing for, what kind of path do you like?"
In the final arc, Tanigawa offers Mitsuhashi money so he'll avenge Imai on the guy who beated him up until he needed hospitalization. Mitsuhashi takes the banknote, then, when Tanigawa's not around, gives it to Itou to buy Imai a melon... Then Itou sees that the note has somehow lost one zero.
In their post-manga side story, Imai and Tanigawa try and impress a girl they saved from a rapist wannabe by telling her of their dream of being Adventures Acheologists even if they're broke. Her common sense and pointing out it's impossible turn it into an Epic Fail that cannot be described by words (aside for Imai accidentally setting his own pants on fire on the crotch).
In this chapter Itou gets a haircut that turns him into a kappa lookalike. The next chapter is Mitsuhashi's attempt at showing it to everyone-and Itou doing everything in his power to keep his hat on.
Mitsuhashi found a bowl that a little girl had said was a "keepsake from Mama", and did everything in his power to protect it, even getting beaten up by a group of punks from Chuu High. Then he found the girl... And the girl's mother explained it was a keepsake from their dog, that they had nicknamed "Mama" when she had puppies.
Right before that, Itou and Riko found out that Mitsuhashi had let himself being defeated to protect it. Not knowing that Mitsuhashi was doing something nice for the sake of being nice, Itou promptly told him that he wouldn't make any money by selling it. It's Itou's reaction at finding out that Mitsuhashi was being genuinely nice that sells it.
When he goes to take revenge for the beating with a curious Imai in tow, Mitsuhashi discovers the guys who beat him up are protected by a Yakuza. Reasoning it was just a fight between high schoolers, Mitsuhashi decided to punch out the main punk... And sent him on the Yakuza.
Seeing just how good at dodging Mitsuhashi was, the Yakuza threatened to kill Imai if he didn't come down and let himself be beaten up. It goes as well as you expect.
In the final battle Mitsuhashi gets stabbed but continues fighting so he'll remain undefeated, and takes advantage of his opponents' shock to take down all the punks. Then he turns to the Yakuza... Who, in terror, reveals he's not actually a Yakuza but a taxi driver who hangs out at their place. Beat up ensues.
Believing that his friend may die with the regret of never paying him back the 2,000 yen he owes him, Itou tells Mitsuhashi to consider the debt paid... And that's when he finds out that Mitsuhashi was faking: he had stolen a fake knife and fake blood from the theatre club...
Final consequence of the above: as they were down when the fake knife was found out, the Chuu High punks started spreading the rumour of "Mitsuhashi the Immortal".
Imai's attempt at confessing his love to Riko: he passed her on the street, turned... And, having suddenly stopped at an intersection, was hit by a bike.
Depressed after confirming that yes, Riko was in love with Mitsuhashi, Imai throws away a punk who was harassing a guy for writing a love letter to the wrong girl. The punk's companion threatens him, warning they're from Akehisa... And he does it while hiding behind a tree.
Mitsuhashi's classmates decide to punish Mitsuhashi for skirting cleaning duty by forcing him to build an arch for the youth festival, giving him only a day. Where to begin?
Itou convinces him to actually do it by praising Mitsuhashi's art assignment, a drawing of a white wall with a fissure on it, saying it represents the many struggles they face in life. He also knows that Mitsuhashi just wanted to draw something easy.
After the first attempt at building the arch gets mistaken for a failed attempt at the gate for a Shinto shrine (and beating up the guys who made the mistake), Mitsuhashi makes a more minimalistic arch. That gets mistaken for a stand to put heads on display.
After that, Mitsuhashi disappears and returns with an arch depicting a castle. The teacher criticizes him, saying it's trash and looks like the entrance of a love hotel and they couldn't expect more from him... And Mitsuhashi starts the Running Gag of hitting teachers with coconuts.
The final panel reveals where the arc comes from: Mitsuhashi stole it from a love hotel sign.
Kyouko knows that Itou is fighting Akehisa. Her reaction after being left behind? Grab a sig to use as club for protection.
