* AwesomeMusic:
** "Concentration" is a piece from the background score that is absolutely wonderful and it's used whenever Bossun is in "Concentration Mode". That is partially due to the fact that the animation wouldn't work if Bossun was just sitting in there thinking and connecting points he missed at simple sight. InUniverse, his "Concentration Mode" is boring and uninteresting for his peers.
** "Cool & Crazy", when stuff is going in favor of the Sket Dan.
** Any song played by The Sketchbook that was used in the anime. Especially "[[http://www.youtube.com/watch?v=HQycEhfmhfM Clear]]" (the last opening of the anime), since it pumps you out.
* DieForOurShip: Initial reaction from the fandom towards Saaya Agata was bad (she is a parody to the {{Tsundere}} character archetype, for starters), but it got worse when she developed a crush on Bossun, the ObliviousToLove hero who wouldn't notice that Himeko also had a crush on him (whose relationship was beyond "LikeAnOldMarriedCouple" status). [[spoiler: Saaya later confesses her feelings to Bossun (and she hints them to Himeko beforehand as well, due to the School Trip Rhapsody arc's circumstances), and she eventually gives up when she finds out that he gives a "special" attention to Himeko that he can't notice besides their friendship.]]
* EnsembleDarkhorse: Several non-characters are so popular they ranked well in the popularity polls, which gets lampshaded in the popularity poll chapters when the characters are flabbergasted to learn about how popular they are. These include:
** Surprisingly, Switch's Bossun drawing, a non-character that has its own popularity inside the series, which was ranked 4th (aka after the main trio and more popular than ''Tsubaki and Agata'') in the first Popularity Poll.
** Anthony (an action figure from "Slender", a tokusatsu-parody show) -- he got 13th (Bossun was only expecting him to be about 75th).
** Tanabe-kun (a "character" that was created by Bossun and Tsubaki in their attempt at fixing the writings in a banner), which got placed 22nd aka the same as ''Shinzou''.
* FriendlyFandoms: With ''Manga/{{Gintama}}'' (although it borderlines into FandomRivalry). Both series have been constantly compared on and off from time to time ever since ''Sket Dance'' was first published, due to their similar premises (resolving problems through an Odd-Jobs Shop) and comedy (BokeAndTsukkomiRoutine, BreakingTheFourthWall, etc.), especially since Kenta Shinohara may have been inspired by ''Gintama'' at the time he was working as an assistant to Hideaki Sorachi. However, both series play off each other's weaknesses and strengths in their own styles, according to their narrative storylines and characters' relationships.
* FunnyAneurysmMoment: Chiaki, "Captain", in episode 4 wants to win the Pelollipop contest because her little brother mentioned to her that the [[CreepyDoll mascot doll]] looks like their deceased mother[[note]]That is because of how similar both of them stick their tongues out[[/note]].
* HarsherInHindsight: Switch's LargeHam personality is a way to show off his emotions to his friends and other strangers as well, and to make him look normal, although he speaks through his laptop. [[spoiler: Until it is mentioned in "Switch On" that he developed it (and his pop culture references' knowledge) when he was a [[{{hikikomori}} shut-in]], as a way to maintain his mind busy at the time he was still mourning the loss of his younger brother.]]
* HilariousInHindsight: Switch, the tech-savvy otaku, now [[NamesTheSame shares his name]] with a [[UsefulNotes/NintendoSwitch video game console]].
* HoYay:
** Soujirou Agata and Michiru Shinba's relationship. They have been best friends since they started High School, and Michiru often worries about Soujirou's well-being when he focuses his attention into an obsession, such as that time he thought there was a LoveDodecahedron involving his little sister, Saaya. The anime, in fact, {{ship tease}}s them a ''lot'' as it uses [[AdaptationDistillation scenes that are nonexistent in the original manga]].
** The UndyingLoyalty that Kiri develops towards Tsubaki sometimes goes into exaggerated extremes -- he agrees with him in anything he proposes, and he has saved his own butt a couple of times. Eventually, Tsubaki gets used to it.
** Switch's loyalty towards Bossun can be interpreted as something ''else'', especially when he initially romanticized [[spoiler: how Bossun "reached his hand" through his room's window to save him in the past]].
* {{Moe}}:
** Obaanyan, a character created for the Sket Dan's reimagined version of ''Literature/{{Momotaro}}'', thanks to Switch's suggestion of changing the old foster mother of the protagonist to someone younger, who ''happens to be'' half cat.
** Koma-chan, who despite being a tall girl seen as a "giant" by her classmates, is incredibly shy and some of her poses in some scenes are a little suggestive to highlight her "moe-ness".
%%* NarmCharm: The show can be really cheesy at times. And yet, it somehow works.
* RelationshipWritingFumble: A chapter in the series, "Brother and Sister", explores the ambiguous ties between Bossun's [[NotBloodSiblings not-blood]] sister, Rumi, and his biological twin brother ([[SeparatedAtBirth who had been separated at birth]]), Tsubaki. They were supposed to see each other as brother and sister, but the way their relationship develop is almost exactly like a romantic set-up of romance mangas (i.e. they have a movie "date", hung out together the whole day, and it ends with Tsubaki saving Rumi from falling off a bunch of stairs).
* UglyCute:
** The mascots from ''"Can Mommy Come Too?"'', a show where Remi Onee-san was its host, have their charm. InUniverse, kids simply adore them despite their appeareances.
** Roman's failing attempts in "drawing".
** Bossun whenever he makes his [[http://iridescence.typepad.com/.a/6a013486c59c61970c01543894fda6970c-800wi "nervous face"]].
