!!From ''Haruhi-chan'':
* AdaptationDisplacement - The animated series is far more widely known in the West than the [[{{Yonkoma}} manga]] it's based off.
* BigLippedAlligatorMoment - The beginning of episode 17.
** The beginning of episode 25. [[spoiler:At first.]]
* CrazyAwesome - Yuki and Tsuruya.
* CrowningMusicOfAwesome
** [[http://www.youtube.com/watch?v=YzXt7Krhoj4 This]] plays during the dodgeball match.
** [[http://www.youtube.com/watch?v=BnRu1_q6n7c Myaa, Myaa, Myanko-logy de Jinrui mya?]]
* EnsembleDarkhorse - Achakura and Kimidori.
** The famous Mikuru sheep from episode 1.
* MemeticMutation
** "You made Mikuru cry!"
** ''Honya~!''
** Yuki's bunny headphones have become synonymous with her Haruhi-chan incarnation.
* SuspiciouslySimilarSong - The theme for the DatingSim intro sound like the ''Nursery Rhyme'' intro "True My Heart". An especially generic example, since "True My Heart" is already memetically generic.
* TearJerker - Episode 24 subverts this when it turned out [[spoiler:Achakura and Kimidori]] were just goofing around.
* WhatDoYouMeanItsNotSymbolic - [[http://static.tvtropes.org/pmwiki/pub/images/haruhichan20090425120029.jpg This part]] in episode 14.
* TheWoobie - Ryoko Achakura.
* {{Woolseyism}} - When Kyon's little sister [[DynamicEntry kicks Kyon upon his opening the front door]] in the first episode, she says ''death'' instead of ''desu'' (they're both pronounced "dess" in Japanese). This joke makes zero sense in English, so the subs give her the vaguely threatening "Nice to see you alive, Kyon!"
** In the dub, she says "Welcome Back Attack" in which Kyon says that she changed a simple greeting into an attack. It works.
** The [[BigBadFriend Yasu]] is the culprit[=/=]TheButlerDidIt change mentioned under ShoutOut on the main page.

!!From ''Nyoron Churuya-san'':
* MemeticMutation
** What caused the series to be made.
** And of course, [[http://knowyourmeme.com/memes/nyoro-n Nyroro~n.]]
* MostWonderfulSound - "Nyoro~n..."
* NightmareFuel: That damned final scene. "[[DerangedAnimation Sumochi banzai!]]"
* TheWoobie - Churuya and Ashakura.
