''Nichijou'' (or ''[[BlatantLies My Ordinary Life]]'') is a Japanese comedy {{manga}} by Keiichi Arawi. The {{manga}} began serialization in the December 2006 issue of Kadokawa Shoten's manga magazine ''Shōnen Ace'', and received an [[AnimatedAdaptation anime adaptation]] by Creator/KyotoAnimation that premiered on Japanese television in [[Spring2011Anime April 2011]].

It is a SketchComedy series about a group of ordinary High School students and their teachers. Except for the robot girl with a wind-up key in her back. Or the girl who keeps bringing guns to school that she [[HyperspaceMallet procures from nowhere]]. Or the Principal who has a penchant for wrestling deer. Or the Science Teacher who occasionally poisons her students (and herself)...

Once available to legally watch online in US and Canada at [[http://www.crunchyroll.com/my-ordinary-life Crunchyroll]], the licensed expired at the end of August 2014.

[[IThoughtItMeant Not to be confused with]] ''[[Manga/DailyLivesOfHighSchoolBoys Danshi Koukousei no Nichijou]]'', also known as ''Daily Lives of High School Boys''.

----
!!''Nichijou'' provides examples of:

[[foldercontrol]]

[[folder:A-F]]
* AccidentalTruth: Yuuko had no idea it actually ''was'' [[spoiler:Nano's birthday]].
* AcmeProducts: Provided by the Daiku Conglomerate.
* AgonyOfTheFeet: Fortunately Nano's toe just comes off. Her big toe does as well: It's instantly launched like a rocket when one spins the screw on her back.
* AllGirlsWantBadBoys: Weboshi likes Nakanojou because she thinks he's a {{delinquent}} due to his mohawk. [[spoiler:This is hilariously inaccurate, and his mohawk is entirely involuntary.]]
* AllJustADream: Chapter 92 of the manga. When [[spoiler:[[EmotionlessGirl Mai]] started acting ''completely out of character'']], Mio realized something was ''very wrong''.
* AmusingInjuries[=/=]SlapstickKnowsNoGender: Yuuko ends up on the receiving end of most of the slapstick gags in this series, especially when she decides to get competitive.
** It knows no species either seeing all the times Sakamoto gets hurt.
* AntiHumor: Sketches frequently end with [[DropTheCow random nonsense]], or even with [[NoEnding no punchline]] altogether.
* ArmCannon: Nano has one hidden in her right arm. It's loaded with beans, so that the Professor isn't harmed when she fires at her.
* ArtEvolution: The art in the manga gets much better as it goes on. It becomes much smoother, and some aspects such as [[CheekyMouth Cheeky Mouth]] start to vanish gradually. This is somewhat reflected in the anime.
* ArtShift:
** During a chase scene in Episode 2, as well as a quick shift to the ED style at the beginning of the episode.
** Actually all over the place, mostly during the MundaneMadeAwesome sequences.
** Extremely prevalent in Episode 19's [[OnceAnEpisode Helvetica Standard]].
* ArtifactOfDoom: Mio's wood cubes ''and'' [[spoiler: Mi-chan's 'mud pie']] (as revealed in Episode 21).
* AttentionDeficitOohShiny: The Professor. Then again, she IS a little kid.
** Also, Sakamoto, when his cat nature takes over and he gets distracted playing with something.
** Mai's dog, Oguri, in Episode 15.
* AwesomeAnimation: Drop-dead gorgeous, even by Creator/KyotoAnimation's high standards. The backgrounds are very highly detailed, seeing real-time perspective shifts in a 2D plane is not uncommon (although some ConspicuousCG is used where it would be otherwise too difficult and expensive to animate by hand, see below), the frames-per-second is remarkably high for this sort of anime.
* BabyTalk: The Professor regresses to this from time to time, befitting her age.
* BadassAdorable: Mio, of course. Misato also counts to a smaller extent.
* BattleAura: Often particularly Mio.
* BerserkButton: Mio upon hearing the compliment that Yuuko's drawing is cool.
** Or whenever [[SeriousBusiness someone messes with her food]].
*** Or if anyone sees her Yaoi manga drawings.
*** While she is a generally nice person, she seems to have a [[HairTriggerTemper Berserk Keyboard]] with all the things that make her mad.
** Mio hits several of Yuuko's during their argument in Episode 14, [[LampshadeHanging signified by a switch being flipped on]].
** Do ''not'' insinuate that robots are not cute in the Professor's presence.
** Nano frequently gets highly upset whenever the Professor installs some useless new feature in her. Later on, the Professor installs a plastic pellet ''machine gun'' in one of her arms. [[HoistByHisOwnPetard This turns out to be a mistake]].
** Sasahara's very ''existence'' is this for [[{{Tsundere}} Misato]]. To the point that you can consider yourself lucky if you manage to talk to her about him without getting hit in return. And don't even '''think''' about suggesting she should admit her feeling towards him. Not even blood relations will save you from her bazooka if you do.
* {{Bifauxnen}}: Ms. Nakamura is easily mistaken for a guy before you hear her voice.
** Even some of the subbers are fooled, making it even less obvious to the viewer.
* [[BigRedButton Big Red Fire Alarm Button]]: Mio is [[SchmuckBait tempted to push it]].
* BigSisterBully: Mio's older sister. She loves pranking just about everyone (even Nano, when she runs into her and accidentally detaches her arm), but her sister is her favorite target.
* BigWhat: The NASA people in Episode 10.
** Annaka is very prone to this; "Eeeehhh?!" is practically her CatchPhrase, and became her ImageSong. She even has a sort of "Big What tennis match" with Takasaki-sensei in Episode 15.
** She has another one with him in Episode 17. Almost the exact same set up and punchline too.
** And of course there is the occasional "DO YU KOTO?" (WHAT IS THIS?)
* BigWordShout: SALMON!
* BlatantLies: Nano learned her methods from the Professor.
* BloodFromTheMouth: When the principal tries to catch a deer that wanders onto the grounds. The deer headbutts him.
* BloodlessCarnage:
** Nano, justifiedly - she is a robot after all.
** Once averted with Sasahara, who bleeds a little after being shot in the head. Most of the time he just turns white from the smoke.
** Though, considering he was ''shot in the forehead with a pistol'', you'd think there'd be a lot more blood involved
* BokeAndTsukkomiRoutine: Yuuko's preferred brand of humor, usually with Mai. She's not very good at it, and Mai (her preferred partner) is ''exceptional'' at being stoic.
* BookDumb: Yuuko. Mio has to cheer her up so she won't feel too bad about her low grades (read: 1%).
* BookEnds: The anime series begins and ends with a section about motivation, complete with a shot of {{cherry blossoms}} popping up spontaneously.
* BookSafe: In one [[ShowWithinAShow Helvetica Standard]] skit.
* BrattyHalfPint: Mi-chan. Also Professor and Misato's little sister.
* BreatheOnTheFan: Yuuko wanted to, [[http://www.youtube.com/watch?v=Y6SSKAuggBQ but a label prohibits her]].
* BrickJoke: Several.
** In episode 2, Mai wins at the stair-climbing game by reciting a password from the original ''Franchise/DragonQuest''. Later in the episode, she's actually trying to play ''Dragon Quest'', only to realize she misremembered the password and can't start her game.
** At the beginning of Episode 8, Nano accidentally activates a RocketPunch. Her right hand then flies across the sky during Sasahara's segment (causing him to write a haiku about it), and comes back again later to sock Misato in the head.
** And at the end of the episode we see Misato cooking at home, with a bump from the head injury she got earlier visible. [[FridgeBrilliance It's also the primary reason why there's no rock-paper-scissors segment that week - that's her rock-paper-scissors hand.]]
** Right in the first episode there's the objects that go flying in the explosion at the start and, more significantly, the poor boy who only shows up atop a chimney at the end of the episode when you've forgotten all about him.
*** At the very beginning of the next episode, the boy walks in front of Mio, Yuuko and Mai as they play the stair game, showing he did, in fact, get down. Somehow...
** In Episode 22, Misato's little sister tries to hit Mio's big sister with a shinai, only to accidentally hit the assistant kendo instructor (who just happened to appear at the right moment), knocking him off of the bicycle he was riding. Later, when Fecchan tries to make the best of having dropped her ice cream by claiming that she can still eat it after cleaning it off, the bike (and the instructor) come by and ruin what was left of her ice cream. In Episode 25, while Ms. Nakamura is walking down the street, the bike is incredibly, still continuing its path without the rider.
*** However, the manga chapters these two skits were based on were consecutive; still, to bother animating the bike at all...
** A dorayaki Tanaka pulls out of his afro for Sakurai-sensei resurfaces in an appropriate 'Short Thoughts' segment later on.
** In Chapter 125, Nakamura-sensei loses control of a robot named Peace-kun, which tackles her and sends her flying through the sky. Two chapters later, both of them suddenly crash down into the principal, who was [[ItMakesSenseInContext struggling to carry a frustrated Mio to the hospital in a wooden cart]].
* BringMyBrownPants: The Professor suffers a late night PottyEmergency, and would've held out if not for a particularly fierce bolt of lightning.
* ButtMonkey: Nano, mostly due to the Professor's rather childlike inventions placed throughout her body.
** Yuuko, whether she accidentally sets Mio off, falls for one of Mai's pranks, [[HotBlooded gets competitive]], annoys her [[AbusiveMom mom]], or just witnesses something weird, the universe doesn't like her. In fact, Episode 23 of the anime gives us a small montage of the universe being mean to Yuuko.
** Mio can qualify as well, since she has to deal with Yuuko, often unknowingly, pressing her BerserkButton, her own CovertPervert tendencies landing her in a position that's far from ideal, and her [[{{TheGadfly}} Gadfly]] of an older sister.
** Sakamoto. Looks like his fate is to be the pet of a well-meaning but careless MadScientist, no matter where he goes.
** It turns out that almost anyone can can get hit with this. Two big contenders are Nakanojou (in addition to his complex about his hair, bad things continually happen to him) and Annaka (what with the universe almost seeming to hate her as much as Yuuko in terms of the weird stuff that gets thrown at her).
* CalvinBall: 'Go-Soccer', kind of. The guy who wanted to invent it (Daiku, the club president) was never actually able to come up with any rules.
** Turns out that there are some rules in the game, as Makoto Sakurai demonstrated in Episode 14. Though what they actually ''are'' is still a mystery. The Go-Soccer match that occurs between Makoto and one of the teachers does nothing except leave even [[EmotionlessGirl Sekiguchi]] with her jaw hanging open.
* TheCameo: The next episode previews are done by various voice actors, expressing the thoughts of inanimate objects that appeared in the show. Almost all of these voice actors are industry vets with 20-40 ''years'' of experience -- for example, Creator/NorioWakamoto was a set of hair decs, Creator/AyaHirano as a shogi piece, etc.
** All the airship segments are filled with cameos of ultra-famous seiyuus doing extremely trivial roles. [[HilariousInHindsight Hilariously enough]], the voice actors of [[LightNovel/FateZero Kirei, Rider and Tokiomi]] all appear one after the other within the span of 5 minutes during the airship sequence in Episode 21, the first two of whom are killed within minutes of each other.
* CannotTellAJoke: The principal tells old jokes that no one gets.
** While Yuuko's are just terrible.
* CannotSpitItOut: Mio with regard to her crush, Sasahara.
** Misato appears to have this regarding Sasahara as well, with [[StuffBlowingUp explosive results]].
** Also, Takasaki-sensei with Sakurai-sensei.
** Apparently now Sekiguchi with Daiku (the two in the Go-Soccer Club).
* CastHerd: While Nano is a student of the high school in the manga, in the anime the segments with her, the Professor, and Sakamoto are kept strictly separate from antics at the school until Episode 14 when Nano finally starts attending.
** Finally, in Episode 16 Yuuko visits the Shinonome Lab and meets the Professor and Sakamoto. HilarityEnsues.
* CaughtWithYourPantsDown: Nakanojo's mother walking in on him trying to make his hair flat is [[DoesThisRemindYouOfAnything played as if it were this trope]].
** In the manga, Yukko gets a little too excited playing with the automatic windup on their new vacuum. When her mother walks in, they both react in this way.
* CheekyMouth: Happens to Mai in Episode 10 where she is blowing a bubble that she subsequently eats.
* CheerfulChild: Professor.
* CherryBlossoms: Used to great effect at the start (and end) of the show.
* ChildProdigy: Despite being only eight years old, the Professor knows enough to build a RidiculouslyHumanRobot and constantly "upgrade" said robot throughout the story without her noticing.
** In Episode 6, when she's told she can get out of the bath when she gets to ten, she says "20 log square root 10". [[DontExplainTheJoke Which is 10]].
* CoincidentalDodge: The final episode contains a scene made of these.
* ClothingSwitch: Episode 16. Yuuko and the Professor switch outfits.
* CloudCuckooLand: Pretty much. The premise of the show is basically mixing [[MundaneMadeAwesome very normal things turned awesome]] with [[UnusuallyUninterestingSight very weird things turned normal]], causing the characters to have a totally inverted perception of what's supposed to be made a big deal.
* ColdTurkeysAreEverywhere: Yuuko swears off doing punchlines the same day Mai cranks her set-ups [[UpToEleven to eleven]].
* ColorFailure: Nearly everyone gets this, sometimes even combined with BlueWithShock.
** A lesser version whenever the principal [[CannotTellAJoke tells a joke]] -- the students are faded and have DullEyesOfUnhappiness.
** People shot by Misato tend to come out completely white as well, such as her younger sister, and especially Sasahara.
* ConspicuousCG: Used for a rotating shot of the entire classroom in Episode 6. The switch back to traditional animation is very smooth, however.
** Also happens during the [[spoiler: Dog and Pen Laser scenes]] regarding the laser fired due to pain. We are given a dramatic circle shot before Yuuko's laser [[spoiler: takes out the rest of the planets]] because she accidentally ''stabbed herself with a pen''.
* ConspicuouslyLightPatch: In Episode 3, Sakamoto walks around under an overturned box in the distant background; the box loses its conspicuous light whenever he stops moving.
* ContinuityNod: The stained glass windows in 1-Q, the main Homeroom. What at first looks like a throwaway gag has consistently been given the nod ever since. Even in the OPENING!
** Episode 23: Mio and Yuuko sport bandages where Mai's dogs bit them the previous episode.
** In the manga, you can very often see other characters in the background, living out the story they were featured in in an earlier chapter, or clearly on their way from what they'd done in the last chapter. This most often happens between consecutive chapters (for example: Chapter 78 ends with the crow flying away. In Chapter 79, you can see the crow, still wearing Sakamoto's ribbon, in the background of the first page), but can go much further in length. Chapter 80 features the Vice Principal's daughter and grandson visiting him. In the background of page 6 of Chapter 75, you can see his daughter and grandson; he's even showing his mother the ball of mud he made for his grandfather. They're also on the first page of Chapter 76.
** Episode 25: When Misato blows out the school's windows and the camera pans out to show it, we can see Yukko chasing Mio briefly... and this is "before" the scene where we see that that was her reaction!
* CoolBigSis: Yuuko seems to have earned this with [[spoiler:the Professor]] in Episode 16.
** [[spoiler: After some rough patches at the beginning, Mai's relationship with the Professor becomes this.]]
* CoolBike: [[GratuitousEnglish Super Bicycle!]]
* CoolPlane: Kenzaburou uses a Blackbird to arrive at school.
* CovertPervert: Mio. The whole chase in Episode 2 was the result of such a moment. Also, in Episode 5, she stops what she's doing immediately upon hearing that Yuuko was going to attempt to draw a cool guy and ends up getting carried away.
** She later ends up trying to turn herself in for a crime she didn't commit and bribe a police officer just to keep him from searching her bag and finding her drawings. When that fails, she beats the crap out of him, Yuuko, the "OH GENTLEMAN" guy, and Sasahara's goat.
* CrashIntoHello: Subverted. When Nano crashes into a boy from school, it results in an EarthShatteringKaboom instead, followed by both parties landing on separate rooftops.
* CreditsJukebox: The second half of the show has a collection of {{Real Song Theme Tune}}s, covered by Sayaka Sasaki and the primary cast.
* CreepyCockroach: In one segment, Nano has a cockroach trapped under a bowl, but is too terrified of it to lift the bowl to kill it (or let someone else do so).
* CurtainsMatchTheWindow: The majority of the characters, though there are a few exceptions, such as Professor.
* CuteBruiser: Mio.
* CutenessProximity: Both Nano and the Professor instantly fall victim to this once Sakamoto sits on Nano's lap in Episode 3. Also, Mai to the Professor in Episode 23.
* DeathAsComedy: The airship segments.
* DeconstructiveParody: Nakamura-sensei visits Shinonome Labs. Knowing that Nano-chan is a robot, and that the Professor is extremely intelligent, she behaves terrified, like a normal person would in a (potentially mad) scientist's lair. She even [[LampshadeHanging notes]] that the Professor appears too young to have built Nano.
* DeniedFoodAsPunishment: Nano frequently threatens the Professor with this, but then either forgets or just simply [[EasilyForgiven forgives]] her for whatever the Professor did to cause said punishment in the first place.
* {{Deuteragonist}}: While the series mostly has an ensemble cast, the first ending and second opening themes treat Yuuko and Nano as this, giving them the most prominent roles within the segments.
* DisasterDominoes: When goof-off Yuuko does her homework and her studious friends don't, they trigger this. The high school trio hides out in a nearby shrine during the rain, Yuuko tries to pay a coin to the shrine, HilarityEnsues, and ends with the entire place destroyed.
* DisproportionateRetribution: Mio [[WrestlerInAllOfUs performs disabling wrestling moves]] on anyone who saw [[MakesSenseInContext or was eating]] the manga she was drawing in Episode 16, whether it's a cop, Yuuko, or a goat.
* DoAnythingRobot: Nano, [[IJustWantToBeNormal much to her chagrin]]. She even has a ''[[FaceFault reaction]] function''.
* DoesThisRemindYouOfAnything: The build up to [[http://www.mangafox.com/manga/nichijou/v02/c025/39.html this page]] is Yuuko swearing off jokes, only for Mai to dial her 'boke'ness UpToEleven. Yuuko's reaction after letting it all out is...interesting, to say the least. Even more so in the episode this skit's featured in (17).
* DoubleStandardAbuseFemaleOnMale: Sasahara gets shot repeatedly by Misato, but the damage seems minimal, including head shots.
* DreadfulMusician: Nano.
* EarlyBirdCameo: [[spoiler: Ms. Nakamura]] is seen looking for Sakamoto in Episode 3 after the Professor and Nano adopt him. The [[spoiler: Kendo assistant instructor]] turns up to offer Mio sage words of advice in Episode 18.
* ElevatorFailure: Happens to Yuuko, Mio, and Mai in Episode 8.
* EmotionlessGirl: Mai acts this way as a vehicle for her pranks.
** Sekiguchi from the Go-Soccer Club, too.
* EpicFail:
** Jumping rope[[note]]Except for Mai[[/note]]. Yuuko's losing her shoes in Episode 14. Mio and any non-combat sport, period. Nakamura with nearly everything. Dolph killing himself.
** Also Annaka's over-sized red ribbon.
* [[EveryoneCallsHimBarkeep Everyone Calls Her "Professor"]]: No one seems to know what the Professor's given name is.
* {{Expy}}:
** Mai basically looks like a [[{{Meganekko}} bespectacled]] [[Manga/AzumangaDaioh Osaka]] with a dull expression on her face. Though many have also been relating [[http://danbooru.donmai.us/post/show/914025/azumanga_daiou-bandana-black_eyes-black_hair-brown Nano's look to Osaka]].
** In contrast to Mai being a stoic version of Osaka, Yuuko definitely gives off Tomo vibes with her similar hair style and TaremeEyes, overzealous earnestness, slacking, and ButtMonkey status, though most of the time she's a good deal less annoying when hyped up.
*** The Professor is like an over exaggerated version of Chiyo-Chan. A blue-eyed red-head ChildProdigy who relapses into childish behavior when overly happy or upset. Her being paired with the Osaka-resembling Nano only makes this ''more'' apparent.
** [[Anime/PaniPoniDash The Professor looks like Becky and her robot Nano looks like Himeko]] [[Manga/KannazukiNoMiko (no relation)]].
** Sasahara looks and acts like [[Manga/TheWorldGodOnlyKnows Keima Katsuragi]], all the way down to the collar, to the point of multiple people calling Sasahara "Keima's long-lost brother". He also reminds many people of [[VisualNovel/AceAttorney Miles Edgeworth]], with his collar and classy attitude.
* ExtremeOmniGoat: Kojirou (Sasahara's goat) is shown eating a piece of paper.
** He took a bite off one of Mio's drawings in Episode 16. [[OneHitKill Poor, poor Kojirou]].
* EyesAlwaysShut: Makoto Sakurai.
* EyeScream: Here's a useful tip: Never tease an extremely violent Tsundere when she's got two sticks of Pocky.
* FaceFault: All over the place. It's one of Nano's [[DoAnythingRobot many functions]], even!
** "Let's go all the way to Okachimachi like this."
* FailureIsTheOnlyOption: Poor Nano.
* FamilyFriendlyFirearms: Double subverted. The guns Misato uses are fairly realistically displayed, and quite powerful since they cause quite some damage to the surroundings. However, it still comes off as this trope since the characters hit are so MadeOfIron that they only end up with smoke emitting from their bodies, and occasionally slight bleeding.
* FieryRedhead: Misato, complete with HyperspaceArsenal.
* FourTemperamentEnsemble: The four main girls at the end of the TV series. Yukko is Sanguine, Mio is choleric, Mai is melancholic, and Nano is phlegmatic.
* FrickinLaserBeams: This is PlayedForLaughs, but Yuuko and Mio can shoot them if they scream in pain loud enough.
* FunnyBackgroundEvent: Oh man the background artists had fun working on this show. Take the second episode - the Go-Soccer club has recruitment posters up on the classroom walls, there's a 'don't sweat it in the hallway' poster up in the hallway, the convenience store has [[BlandNameProduct Wou~i Ocha]] [[note]]parody of 'Ooo-i Ocha', the first sound representing a shout across a field[[/note]] and 'Overcooked Soup' (the black one being sold for 100 yen - cheaper than the others!), the list goes on.
* TheGadfly: Mai. Almost makes you wonder why Yuuko and Mio are friends with her sometimes.
** Also Mio's sister.
[[/folder]]

[[folder:G-L]]
* GagSeries: Pretty much.
* GenkiGirl: Yuuko. In the manga, her introductory character description is the single word 'genki'.
** Misato's friend Fecchan.
* GeniusDitz: Yoshino, according to Misato "all she can do is kendo".
* GettingCrapPastTheRadar: Sakamoto's comment to Nano, "You look just like any other girl". He says it while looking up her skirt.
* GirlishPigtails: Mio and Misato's little sister.
** Sakurai-sensei, sometimes.
* GratuitousEnglish: LOTS.
** In Mio's ImagineSpot:
--->'''Sasahara:''' Happy New Year.\\
'''Mio:''' M...me too!
** Yuuko is prone to outbursts of gratuitous English when shocked or utterly confused.
*** '''GOD IS DEAD'''
*** '''Koucho (Principal) DEATH'''
*** When she is forced to wait a very long time for her order at a restaurant: "''[[PrecisionFStrike Goddamn!]]''"
*** Episode 11, ''Super Ultra Great Delicious Wonderful Yabai'' ("yabai" is Japanese for "bad"). Her attempt to catch a cold ''Come On, Come On'' too, which was especially amusing as she was trying to catch a cold in order to avoid having to take an English exam.
** Nano in Episode 6 when she's trapped a [[WhyDidItHaveToBeSnakes cockroach]] under a bowl.
*** '''Death or Die!'''
**** '''Good Timing!'''
***** '''R-R-R-Rock and Roll!'''
** [[TheGadfly Mai]] after catching a fish: ''Release.''
** The whole rocket launch sequence.
** Off za book
** Episode 12 has several instances, including a segment ("Killing Time") centered around ''not'' using English words.
** Also from Episode 12, two back-to-back "Things We Think Are Cool" segments each have multiple instances: "NICE CATCH!" followed by "Oh! Superball! and "WOW!" followed by "Oh! Slipstream!"
** "Oh! Gentleman!" The manga expands that joke specifically quite a bit, with several pages containing no dialogue but sound effects all written in Roman letters along with such English outbursts.
** In Episode 17:
--->'''Takasaki:''' NO FUTURE!!!\\
'''Takasaki:''' Gonna Move!!
*** "SEE YOU SOON!"
** In episode 18 we have "Trick or Treat" and:
--->'''Yukko:''' Nice timing, announcer!
** Episode 19:
--->"Domestic violence!"
--->'''Ogi:''' A final ''rabudo''!
** Episode 21:
--->'''Takasaki:''' GOOD! ENOUGH!!!
** Episode 24:
--->"Delicious."
--->'''Mio:''' [[GratuitousFrench RENDEZVOUS]]!
** Episode 25:
--->'''Nakamura-sensei:''' SHOULDER BLOCK!
* [[GratuitousJapanese Gratuitous Romaji]]: "TORETA!!!"
** A more classic example of GratuitousJapanese : In the Helvetica Standard segment of Episode 9, as Chirashizushi spells her name to the Tengu, each syllable is accompanied by its corresponding Japanese characters.
* GratuitousForeignLanguage: Yukko's defeault greeting, "selamat pagi!" is actually Malay/Indonesian. [[RuleOfCautiousEditingJudgement Flame wars has been fought to determine which of the two languages Yukko (tried to) speak]].
* GretzkyHasTheBall: Episode 7 has the Professor and Nano playing baseball with Sakamoto officiating, but neither player has any idea how the game works.
* HairDecorations: Mio's hair ties are small blocks of wood.
** With an epic story behind them. Which gets a sequel in Episode 18... [[spoiler: when we learn about where her pigtails come from]].
*** Both of which turn out to be [[spoiler: part of a trilogy that is concluded]] in Nichijou (Uchuujin), the PSP VisualNovel. [[spoiler: Maybe.]]
* HairTriggerTemper: Mio. At least she's the one who's angered most easily, due to all the things she considers SeriousBusiness, and her overreaction to them.
** Second only to [[{{Tsundere}} Misato]].
* HamToHamCombat: The Go-soccer match between Makoto vs Takasaki-sensei.
** Mio and Yukko often.
* HeadPet: Yuuko and Nano in the first ED.
* HeadphonesEqualIsolation: Mai is virtually shut off from her surroundings when using ear buds, as Yuuko finds out.
* HereWeGoAgain: The last segment of Episode 26 is quite similar to the first one from Episode 1. It even has the same title.
* HereditaryHairstyle: Nakanojou and his father (the daifuku guy), as revealed in Episode 16.
* HighPressureEmotion: Nano literally ''overheats'' as she reads Mio's manga.
* HonestAxe: Yoshino pulls a rather insane variation with fish sculptures.
* HurricaneOfPuns: The Professor uses this to test Nano's ''[[FaceFault reaction]] function'' in Episode 15.
* HyperspaceArsenal: Misato.
-->'''Sakurai-sensei:''' U-um, you're not allowed to bring that to school!
* IceCreamKoan: Pretty much every episode has at least one.
* IJustWantToBeNormal: Nano, big time.
* IJustWantToHaveFriends: Nano's main reason for her [[IJustWantToBeNormal wanting to be normal]].
* ImagineSpot: Yuuko's in-class dreams of the Fey Kingdom. Takasaki-sensei and Mio occasionally have these with their respective love interests. Mio once even comes up with an entire romantic scene for Nano and Sasahara when Yuuko convinces her they're dating, complete with a slight ArtShift.
* InSeriesNickname: "Yukko" for Yuuko.
* IncrediblyLamePun: In one manga chapter (Episode 8 in the anime), Yukko tries to get a rise out of Mio and Mai with a series of bad Japanese puns and only gives up after they get to school with no reaction whatsoever.
* InformedAbility: We never actually ''see'' the Professor do any research. She seems to spend most of her day with typical activities for an eight-year-old, like reading picture books.
** The books are sometimes vaguely science related, but it still doesn't explain much.
* InstantBandages: Yuuko sports some on her head in Episode 24 shortly after Mio finds out that she was lying about Sasahara and Nano getting a little too friendly with each other.
* IronButtmonkey: Yuuko - considering the universe that she lives, she needs to be. Sakamoto also counts, to a lesser extent.
* IwoJimaPose: Mio imagines raising a ''Sasahara'' flag this way when she talks to him at the drinks machine in Episode 24.
* {{Joshikousei}}: The series is a lot like ''Manga/AzumangaDaioh'' [[ThisIsYourPremiseOnDrugs on lots and lots of acid]].
* {{Kendo}}: Mio's sister, Misato, her sister and Sasahara practice this. Mio herself used to pratice it, too.
* LongTitle: One of the remixes of the opening song is called "Hyadain no Kakakata☆Kataomoi-C 'Forbidden Cats' sakamoto playing the Orchestronica REMIX".
* LoveHurts: Happens to Mio in Episode 25. She ends up taking a very long run in the process...
* LuckyCharmsTitle: The opening song is called "Hyadain no Ka-ka-kata☆Kataomoi-C".
* LuminescentBlush: Misato, bordering on HighPressureEmotion.
[[/folder]]

[[folder:M-R]]
* MadScientist: Both the Professor and Nakamura-sensei. The former is much nicer and much more competent, though.
* MadeOfIron: Sasahara can take everything Misato gives him and barely shows any damage.
* MagicSkirt: Oh so much. Three glaring examples are when Yuuko does a fliptake after making several horrible puns (What nice tenki (weather) today... I MIGHT BUY A TEN KEY PAD!) and yet her skirt magically stays up. Another is her time spent as the coffee shop. Several angles show her throwing herself around in frustration at being unable to buy an expresso, and most of them are at her legs yet her skirt is always protected by a wonderfully convenient impossibely cast shadow. The last major one is when Mio does a 50-foot jump into the water.
* MaybeEverAfter: The anime does this with [[spoiler:Kenzaburo/Yuria]] and [[spoiler:Sasahara/Misato]].
* MinorInjuryOverreaction: Yuuko accidentally presses the sharp end of a pen, and [[http://www.youtube.com/watch?v=OLBePOVvczs& destroys the solar system]].
* MistakenForBadass: Due to Nakanojou's natural mohawk, many of his classmates believe he's a [[{{Delinquents}} delinquent]].
* MoeCouplet: Nano and the Professor.
* MomentOfWeakness: Inverted when Mio & Yuuko get into a serious argument. Yuuko accidentally blurts out a sincere complement and the argument ends up defusing, [[CrowningMomentOfHeartwarming in a very cute way]].
* MoodWhiplash: Mio's Heroic BSOD run in Episode 25. You think this might be the show's first TearJerker.... then Mio ''jumps out of the window''.
* MoreDakka: Misato. As she gets more and more embarrassed, she pulls out bigger and bigger guns (getting as far as a bombard at one point).
** Nano uses this on the Professor after discovering she had a machine gun installed on her right arm. Fortunately it only shoots BB's, but that doesn't stop Nano from shooting the Professor repeatedly as a result.
* MundaneMadeAwesome: With its over the top jokes and everyone generally overreacting to everything, this show may as well be called "Mundane Made Awesome: The Series."
* NeverMyFault: Whenever Nano expresses displeasure with one of the Professor's practical jokes, it immediately becomes Sakamoto's idea. Nano does sometimes falls for it, though.
* NoGoodDeedGoesUnpunished: Once in a while Sakamoto will let himself fall for one of the Professor's pranks only for said prank to be more than he bargained for.
* NoNameGiven: The Professor and Misato's two friends Fecchan and Weboshi.
* NonStandardCharacterDesign: All birds on this show are drawn realistically...with the exception of the crow voiced by Creator/DaisukeOno, who could best be described as a [[LimitedAnimation two-framed]] black cone.
* NoseBleed: In an early episode, Mio suffers a subtle one after having an ImagineSpot with Sasahara in it. In the next scene her nose is plugged with tissue and her friends are carrying her away.
* NotSoAboveItAll: Sakamoto. For all his protesting he can be caught up in his catlike behaviors more easily than he likes.
** In manga chapter 141, Yuuko is repeatedly pulling out the retractable vacuum cleaner cord and experiencing euphoria when it snaps back into position. She gets told off by her mother... who proceeds to do the exact same thing.
* OffModel: Yukko's 'cool guy', George Samidare.
* OnceAnEpisode: There are actually several of these.
** One is two people wearing the daifuku "costume" from chapter 16 swinging a jump rope, and one of the characters attempts to join in.
** Then there's the Professor and Nano playing Rock-Paper-Scissors, only the Professor's modified Nano in a way that's either humiliating, or works things out in the Professor's favor. In later episodes, the two do a little dance instead.
** More recently, the "Things we think are cool!" segments.
** Even more recently, the "Like Love" and "This is..." segments.
** The Rock-Paper-Scissors segment made a comeback in Episode 26. [[spoiler:Nano finally wins! ...But Sakamoto accidentally covered the Professor's face, preventing her from seeing it.]]
* OnlyKnownByTheirNickname: Misato's two friends Fecchan and Weboshi.
* OnlySixFaces: There are only four or so unique faces, and even those are subject to [[ArtShift change]] based on the situation. This is actually the source of a lot of stylistic parody -- the school trio and scientist trip lend themselves well to being photoshopped into other character's costumes.
* OnTheNext: Delivered by something from the preceding episode that you wouldn't think would be able to talk (an apartment, coins, ''onomotopeia''), voiced by a different voice actor, and amounts to little more than bemused ramblings, [[AvertedTrope not about anything related to the next episode]].
* OvercomplicatedMenuOrder: After Yukko fails miserably at ordering off the complicated new coffee list, she invites Mio to the same coffee shop to watch her fail, but Mio flawlessly recites one of these.
* OverlyLongGag:
--> '''Professor:''' Hakase da nyan!\\
'''Nano:''' Moe desu!\\
'''Professor:''' Hakase da nyan!\\
'''Nano:''' Moe desu!
** Annaka going "[[BigWhat Eeeeehhhh?]]" [[http://www.youtube.com/watch?v=S-abIgFesWM in Episode 10]].
** The Professor's tantrum for shark sponge cake in Episode 13.
** Episode 21 features a RepeatCut of Takasaki-sensei giving Yuuko a light smack on the head with his class binder. As in, repeated over 50 times.
* PaperThinDisguise: Nano thinks she's fooled everyone into thinking she's a normal, human girl. She hasn't as seen with Mio's older sister.
* ParentalAbandonment: Seems to have happened to the Professor. Not that she minds.
** The Principal seems to have a relation to [[spoiler:the Professor, as his last name is revealed to be Shinonome]].
* PinPullingTeeth: Misato Tachibana does this in one episode.
* PocketProtector: The coin-sized cutting board that Mio recieved from a vending machine a few chapters earlier shields her heart from getting pierced from a projectile spike.
* PoisonedChaliceSwitcheroo: Nakamura inflicts this on herself in Episode 15.
* PowerTrio: Two sets. Mio (super-ego), Yukko (id) and Mai (ego) before Nano appeared. Also Misato, Fecchan, and Weboshi.
* ProductPlacement: Snickers, in Episode 14. Credited at the end, even.
* PromotionToParent: Oddly enough, Nano often plays the parental role with regard to the Professor, sometimes helped (or hindered) by Sakamoto. Well, the Professor is still a little kid after all.
* PuniPlush: Also has a bit of ''Manga/AzumangaDaioh'' influence as well.
* PurelyAestheticGlasses: Sasahara's glasses are "just for show". Misato, who accidentally broke them and thought he was BlindWithoutEm, was ''not amused''.
* TheQuietOne: Mai.
* RealSongThemeTune: In its second season, the series started using a different Japanese pop standard for its ending theme every episode.
** A portion of the [[http://www.youtube.com/watch?v=_679sSiQ4dw FIFA Anthem]] was played during the "10-yen Soccer" segment.
* RepeatCut: Episode 21 feature a single shot repeated over [[OverlyLongGag fifty times]].
* TheReasonYouSuckSpeech: Done to Yuuko by Mio in Episode 20... over [[SeriousBusiness drawing paper]].
* RidiculouslyHumanRobot[=/=]RobotGirl: Guess who.
* RocketPunch: Nano has one. And a rocket ''toe. A USB rocket toe''.
** Nano seems to have no control over the timing of said RocketPunch. It just fires when it feels like it.
* RuleOfCool: Not only does Daiku's family own an [[http://en.wikipedia.org/wiki/Sr-71 SR-71 Blackbird]], but it's also either VTOL capable or the chauffeur (or Daiku himself) is somehow capable of landing it on the school roof.
* RuleOfFunny: This series' bread and butter.
* RuleOfThree: Episodes 8 and 9 both have a "Things we think are cool!" segment, done by the schoolgirl trio. In Episode 10, it's subverted -- Mai does the segment herself, in her [[EmotionlessGirl usual manner]].
* RunningGag: Yuuko has a tendency to throw together haiku on the fly, but she consistently ends them all with "Mogami-gawa" (Mogami River). This is a parody of the rather large number of haiku by Basho that do the same.
** Whenever in trouble, the Professor tries to convince Nano that Sakamoto told her to do it or that Sakamoto was a partner in crime.
** Throughout the series, when Yuuko is having a hard time, this one dog walks up to her and puts a paw on her to comfort her. A couple times you see him running long distances (with his master in pursuit) to reach Yuuko.

[[folder:S-Z]]
* SayMyName: [[http://www.mangafox.com/manga/nichijou/v02/c019/22.html When the Professor names Nano.]]
** And after the Professor allow Nano to go to school.
** Yukko during Mio's HeroicBSOD run.
-->'''Yukko''' "MIO CHAN!" and "CHAN MIO!"
* SceneryPorn: Just the standard for Creator/KyotoAnimation.
* SchoolgirlLesbians: Mai starts spouting lines that sound very much like a confession to Yuuko. [[spoiler: But she's not serious. Probably.]]
** Mio mentions that Yuuko wakes up despite not being kissed, Yuuko questions why and Mio blushes.
* SchmuckBait: Sakamoto usually falls for these from the Professor.
* {{Sensei-chan}}: Sakurai-sensei, who acts more like a timid schoolgirl than a teacher.
* SeriousBusiness: Being a daifuku mascot, to the daifuku guy.
** Mio and drawing. Especially her Yaoi drawings/manga.
** Go-Soccer, as seen in Episode 19.
--> '''Ogi:''' Someone may even die.
** Mio and food. In Episode 14, Yuuko bought her yakisaba by mistake instead of the yakisoba she wanted, and she ''flipped the fuck out''.
* {{Shiritori}}: Mio and Yuuko play a picture version while passing notes in class. It quickly goes downhill.
* ShoutOut: [[ShoutOut/{{Nichijou}} at the subpage]]
* ShowWithinAShow: ''Helvetica Standard'', which is just as weird as the main show.
** TheGrimReaper is a recurring character. A bit of a klutzy reaper, though.
* ShrinkingViolet: Sakurai-sensei. Except around her little brother.
** The Coffee Shop girl.
* SilenceIsGolden: Episode 17. Card Pyramid.
** The Shrine Incident segment.
* SillyMeGesture: The Professor often does this when questioned by Nano about the latest weird device she has installed on her.
* SistineSteal: Mai pulls this off on Episode 4, in the ''middle of an exam'', by touching a drawn hand on a chalkboard. The manga attributes this as an homage to ''Film/ETTheExtraTerrestrial''.
* {{Slapstick}}
** SlapstickKnowsNoGender: Or species, for that matter (see AmusingInjuries above).
* SomethingCompletelyDifferent: The sketches involving the Fey Kingdom zeppelin. They're actually unusually long and elaborate {{Imagine Spot}}s of Yuuko about Mio's wooden hair ties.
** One segment in Episode 8 shows the three trapped in an elevator, resigned to the fact that no one will rescue them. [[DespairEventHorizon Their despair eventually causes them]] [[LaughingMad to go mad with laughter.]] [[spoiler:[[WhatHappenedToTheMouse It all means absolutely nothing because two segments later they're all apparently rescued but we don't see how.]]]]
*** The way the anime portraits the trapped elevator scenario treads dangerously close to NightmareFuel.
** Another example is the "MEGANE MEGANE MEGANE" scene at the beginning of Episode 19.
* SolarPoweredMagnifyingGlass: Episode 16. Used by Mai to slightly burn Yuuko's hand when the latter was playing a game of guess which hand has the eraser.
* SpannerInTheWorks: Yukko in "My Ordinary life 111" complete with Convenient Dodges.
* SpoilerOpening: It's difficult for such a wacky and episodic series to really have such a thing as a spoiler, but both openings lift scenes directly from stories that appear later in the show.
* SpringtimeForHitler: Yuuko's attempt to catch a cold would in real life have given her hypothermia. Of course, she wakes up completely healthy.
* StandingInTheHall: Yuuko ends up like this quite often.
* StatusQuoIsGod: Semi-averted for Nano in Episode 13 - the Professor allows her to go to school, which was the status quo in the manga from the start... Although outside of two gags early on, all of Nano's scenes in the manga involve the laboratory in some way.
* StrongFamilyResemblance: Sakurai-sensei and her little brother, all the way down to the hyperhidrosis.
** Misato and her sister Mihoshi.
* StuffBlowingUp: Oh so much.
* SuperWindowJump: See your crush arm-in-arm with someone else? [[http://www.youtube.com/watch?v=4K4Ry2rFWhI Jump out the window]] and keep running.
* [[SurprisinglyForeignLanguage Surprisingly Good Malay/Indonesian]]: Yuuko and Mai were greeting each other in Malay/Indonesian in Episode 1. Not only what they are saying is correct (including Yuuko correcting Mai that she should have replied "''Selamat pagi''"(Good morning) just like what she said earlier, not "''Selamat malam''"(Good night)) but their pronunciation was good as well.
** "Selamat tinggal" also. Meaning "Farewell".
** There is speculation about more surprisingly good Malay/Indonesian. It's the Kuma (bear) joke. When Mio's sister takes the money from Mio, she says "Aru toki wa kuma, soshite aru toki mo ku-ma", which means "Sometimes I'm a bear, sometimes I'm a be-ar". In Malay/Indonesian, kuma (bear) is translated "beruang". It could be separated into ber-uang (ku-ma), which means "has money". If it's [[BilingualBonus intentional]], the author speaks surprisingly good Malay/Indonesian, to the point that he can make Malay/Indonesian puns that possibly no Japanese person will understand.
** There's also a few "Gamelan" posters here and there. A gamelan is a traditional Indonesian and Malaysian instrument
* SuspiciouslySpecificDenial: "It's not like turning it will turn my thumbs into USB ports like a robot or anything..."
** [[{{Tsundere}} Misato]], ''each and every time'' Sasahara is mentioned.
---> '''Misato:''' Why do I have to marry him?!
* TakeAThirdOption: Episode 4: You've forgotten to buy your cat food because you bought a snowman on a whim and were then blackmailed by your creator into buying her snacks, so what do you do? [[FridgeBrilliance Feed him shaved ice.]]
* TalkingAnimal: Sakamoto, the Professor's pet cat, thanks to a scarf she made for him.
** Which she then "borrows" to put on a crow in Episode 17. Sakamoto gets it back later.
* TemptingFate: "I should be happy that I wasn't hit by any raw foods." Not even five seconds later...
** Mio in Episode 5: "I can't believe I drew that picture. Even though I lost control, it could have been worse." Cue naughty picture being used as part of a quiz.
* TheReasonYouSuckSpeech: Mio occasionally gets so mad at Yuuko that she rants about the stupid things the latter has done. Yuuko does it to her once in a while as well, usually in an epic, HamToHamCombat style.
* TheScapegoat: The Professor is almost always quick to blame Sakamoto for any misfortunes, or at the very least, try to make him a guilty party to it, such as when she knocked down the laundry line while it was raining, then trying to claim he told her to drop the clothes in the mud. Nano however, hardly ever finds him guilty of those incidents, and instead punishes the professor instead. [[EasilyForgiven Or not...]]
* ThirdLineSomeWaiting: The anime is currently divided between two main plotlines and multiple minor plotlines. The stories around Mio, Yuuko, and Mai and the story at Shinonome Laboratories are presented in equal measure. The running plot about the Go-Soccer Club is presented less than a minute at a time. The teachers' romance and Misato/Sasahara also get their day, but infrequently.
** Meanwhile in the manga, there's a bit more overlap between Mio and Nano, as Nano starts out as a student in the manga -- everyone knows she's a robot, but are too polite to tell her they figured it out. This was changed for the anime in order to more [[CastHerd decidedly separate]] the Shinonome Laboratory skits.
* ThirdPersonPerson: The Professor. Justified by her age -- referring to yourself in third person is markedly childlike in Japanese.
* [[ThisIsADrill This Is A Corkscrew]]: How Mio punishes her older sister.
* ThrowTheDogABone: Yuuko is sent to stand in the hallway after forgetting her homework at home - the homework she ''remembered to do all by herself, for once''- and a dog appears standing next to her. It puts its left paw on her shoulder. A universe out to get her, yet a small dog is ironically the one to throw her a bone!
** Later in that episode she gets an 80 on a test though it's [[YankTheDogsChain subverted]]: The class average was 92.
** Buddy (the name of the dog) does it again in Episode 14. [[PetTheDog Pet the Human?]]
*** Buddy also makes an appearance as early as Episode 6 on the girls' camping trip and in Episode 8 when Yuuko tells her awful jokes, where he can't reach her.
*** Looks like Buddy is a recurring character now. He even shows up in the new opening!
*** He has a smaller companion that serves the same function for Mio. His name? Kobuddy (little buddy).
*** ''Both'' of them show up after Yuuko and Mio get trolled by Mai's dogs. Unfortunately, being dogs they still scare off Sakamoto and the Professor.
** Nano gets one when the Professor lets her go to school.
*** And a really big one when Yuuko basically tells her she doesn't mind about her being a robot.
*** Episode 26 is basically one big bone for Nano.
* TitleDrop: Several times:
** Sasahara, in Episode 4, in his typical overdramatic fashion. With bombastic background music.
** Nano, in Episode 26, when she's remembering her life with her key.
** Episode 25, from the page quote:
-->''"I once overheard Sasahara-senpai talking to someone... Our everyday lives may, in fact, be a series of miracles. They just may be... no, I believe they must be..."''
--->'''-- Mio Naganohara'''
* TrademarkFavoriteFood: The Professor loves omelet rice and strawberry juice. She also loves Sharks, including "Shark Cake".
* TrainingMontage: Possibly parodied in Chapter 59/Episode 79. When Mio can't do the high jump properly, Yukko agrees to train her. This results in a training montage featuring clips of Mio and Yukko jumping set to inspirational music, and includes a clip of Mio being given inspirational words by the Kendo instructor about what hard work can do. Mio then tries the high jump one last time; but instead of getting it right, it results in her failing even more spectacularly then before.
* {{Troll}}: Mai, of course. She even trolls Hyadain [[http://www.youtube.com/watch?v=kUgqIPKMRy8 in her character song]], by inviting him to sing the male parts before letting her time cut out in the middle of one of his lyrics.
** With no one else around, Mai will [[http://www.youtube.com/watch?v=3hKqYi2E9vY troll herself]].
** As seen in Chapter 143 of the manga, not even Mio's sister can beat her at trolling.
* {{Tsundere}}: Misato is a Type A taken to ridiculous proportions.
** You could even call her a [[HyperspaceArsenal gun]][[IncrediblyLamePun dere]].
** Nakamura has a bit of this, given her flustered reactions whenever someone calls her cute.
* TwoTeacherSchool: Averted. There are lots of teachers who get the appropriate amount of attention.
* UncattyResemblance: [[http://www.youtube.com/watch?v=pi2KmRU9tcU Mai's puppy]] seems to be as big a troll as she is.
* UnsoundEffect: '''GASCOIGNE!'''
* UnstoppableRage: In Episode 16, Mio lays waste to all who sees her Yaoi drawings.
* UnusuallyUninterestingSight: A girl with a big key in her back? Who lands on a roof? Huge explosions obliterating cars? Nobody in the town seems to care.
** Misato's guns and Sasahara smoking head and charred clothing because of said guns.
** Often Sakurai-sensei subverts this and does notice, with rather odd results.
** In-universe, Yuuko is surprised when no one responds to the fact that she's saying "selamat pagi" instead of "good morning".
* UpperClassTwit: Sasahara, though given his actual background it may be more Upper Class Twit Wannabe.
* UpToEleven: In Ch. 167 of the manga, Yukko nearly dies choking on a piece of daifuku. Twice. Mio also almost chokes to death on the SAME PIECE.
* VengefulVendingMachine: Sasahara encounters one, the vending machine dispenses the drink ''then'' the cup.... and declares it a WorthyOpponent.
* WackyHomeroom
* WaveMotionGun: Mio's and Yūko's screams of pain are capable of destroying roofs, skyscrapers, and ''planets.'' "Aaaah," indeed.
* WhamEpisode: Episode 13. [[spoiler:Nano will go to school.]] Definitely worthy of a DynamicEntry.
** Episode 14 proves ''why'' this is such a big deal, as it changes the dynamic of the school scenes. Then it turns it UpToEleven with a full-scale shouting match between Yuuko and Mio, and the revelation that [[spoiler: Go-Soccer is ''an actual sport'']]. [[ArsonMurderAndJaywalking And there's a new opening.]]
* WhenSheSmiles: Mai with her usual dull, emotionless expression, becomes rather adorable the few times she smiles, or even laughs.
* WhyDidItHaveToBeSnakes: Nano is absolutely terrified of cockroaches and lightning (understandably, since she's a robot).
** The Professor can't handle dogs, she even mentions it in both of her character singles. She's also scared of lightning as well, but considering she's only eight, that's not surprising at all.
** Sakamoto is also scared of dogs, but again, that's perfectly normal for a cat.
* WidgetSeries
* WindUpKey: Nano's most noticeable feature, much to her dismay. Not only is it a dead giveaway to the fact that she's a robot, but it's also useless: its only purpose is to launch Nano's toe like a rocket when spun manually. The Professor still absolutely refuses to remove it, as she finds it cute.
* WikiWalk: One of the school faculty members has one in Episode 11.
* WiseBeyondTheirYears: Subverted. The Professor might be able to build [[RidiculouslyHumanRobot robots that can eat and feel emotion]], but she's still a little kid emotionally.
** Nano as well. Physically and somewhat emotionally she acts like a high-school student, but she is (for the most part) very skilled and mature as acting as a ParentalSubstitute for Professor.
* WithFriendsLikeThese: Yuuko, Mio and Mai all get on each others' nerves at different points. But, beneath it all, they're VitriolicBestBuds.
* WordSaladTitle: ''Helvetica Standard'', which incidentally is the [[UsefulNotes/{{Fonts}} font]] that the English component of ''Nichijou'''s logo is typeset in.
* WorldOfHam: Where preventing a sausage from falling on the floor is a breathtaking adventure, and being bitten by a dog results in an Earth-shattering nuclear explosion.
* WrestlerInAllOfUs: The principal finishes off the deer in the schoolyard with a [[SuplexFinisher suplex]] after [[EpicFail completely missing it with a moonsault]]. [[http://www.youtube.com/watch?v=ApKE01R9DyY As seen here.]]
** Mio hits Yuuko with a Dragon Screw and later a crossbody when she chokes and coughs into the food.
** Yuuko's mom performs what appears to be a modified Japanese arm drag on Yuuko during her fit in Episode 10.
** Makoto Sakurai performs a german suplex ''on himself'' in Episode 14.
* YaoiFangirl: Mio is caught a few times doodling Yaoi characters. She's also a rather big fan of drawing pretty boys in general.
** Judging by her reaction to Mio's manga, possibly Nano.
*** Of course, she could just be incredibly flustered because she's never seen anything quite so... scandalous. (She was built and raised by an eight-year-old, after all.)
* YouGottaHaveBlueHair: Mio, her sister Yoshino, and Nakamura for the trope specifically, and pretty much every other color in the known universe throughout the rest of the cast.
