* AwesomeMusic:
** "Concentration" is a piece from the soundtrack 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, it would be seen as boring and uninteresting, too.
** "Cool & Crazy", when stuff is going in favor of the Sket Dan.
** Any song sung 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's made to pump 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 in Bossun, the ObliviousToLove hero who wouldn't notice that Himeko also had a crush on him (whose relationship was beyond "LikeAnOldMarriedCouple" status). [[spoiler: She later confesses her feelings to Bossun (and she hinted it to Himeko as well, due to the School Trip Rhapsody arc's [[FreakyFridayFlip circumstances]]), and eventually gives up when she finds out that he gives a "special" attention to Himeko that he doesn't notice besides their friendship.]]
* EnsembleDarkhorse:
** Surprisingly, Switch's Bossun drawing, a non-character that has its own popularity inside the series, made up to have a place in the Top TEN of the first Popularity Poll.
** The series has a lot of non-characters that are popular with the readers, as the second popularity poll revealed. Among the other notable ones are Anthony (an action figure from "Slender", a tokusatsu-parody show) and Tanabe-kun (a "character" that was created by Bossun and Tsubaki in their attempt at fixing the writings in a banner).
* FriendlyFandoms: With ''Manga/{{Gintama}}'' (although they also borderline 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, they also both play off their respective 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 said the [[CreepyDoll doll]] looks like his 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 even though he speaks through his laptop. [[spoiler: Until it is showed 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.]]
* HoYay:
** Soujirou Agata and Michiru Shinba's relationship. They have been best friends since they started High School, and Michiru often worries about Soujirou, even more when he gets obsessed into something and doesn't work like his usual self, such as that time he thought there was a LoveDodecahedron involving his little sister, Saaya. The anime, in fact, plays a lot more into ShipTease with them as they use [[AdaptationDistillation scenes that weren't in the original manga]].
** The UndyingLoyalty that Kiri develops towards Tsubaki sometimes goes into exaggerated extremes, where he is agreeing with him in anything, saving his own butt, and he stands ''too'' close to him. Eventually, even Tsubaki gets used to it.
** Switch's loyalty towards Bossun can be interpreted as such, especially when he initially romanticized [[spoiler: how Bossun "reached his hand" towards his room's window to save/help 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.
%%* 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 of "drawings".
** Bossun whenever he makes his [[http://iridescence.typepad.com/.a/6a013486c59c61970c01543894fda6970c-800wi "nervous face"]].
