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.
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!"
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.
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. 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 ground beforehand.
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.

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.
