* GodNeverSaidThat: When Chapter 83 revealed the cup sizes of the female students, it caused a HypeBacklash from the [[ColdSniper Rinka Hayami]] fans because they knew that it's impossible for Hayami to have a D-cup. The ''Shounen Jump'' redaction admitted that their editors made a mistake and accidentally switched Hayami and [[FatGirl Sumire Hara's]] cup sizes (C-cup and D-cup, respectively). Unfortunately, the English fan translators didn't correct that mistake.

* IKnewIt: A lot of people called it that the end of the classroom civil war was going to be a duel between [[spoiler:Nagisa and Karma]].

* ActorAllusion: Yuzuki Fuwa shares the same [[Creator/KanaUeda voice actress]] and character type of [[Manga/MajinTanteiNougamiNeuro Yako Katsuragi]], the heroine and kid detective of [[Creator/YuuseiMatsui the author]]'s previous series.

* MinimalisticCoverArt: The volume cover art is usually nothing more than two solid colors and Koro-sensei's smiling face. Special mention goes to Volume 5, which resembles Koro-sensei's [[http://fyeahassassinationclassroom.tumblr.com/post/83714736434/heliohapt-assassination-classroom-volumes-1-9 poker face]]: a blank cover and the ._. emote.
** Volumes 1-7 are actually Koro-sensei's emotional colours. In order; normal, smug, sleepy, happy, indecisive, disappointed, and angry. Volume 8 shows his Ultimate Defensive Form.

* CastingGag:

* TooSoon: Episode 3, which featured "a character swinging a knife to kill a monster", was delayed by a week due to a hostage situation in the Middle East. Two Japanese men were being held by hostage by the terrorist group ISIS, and the deadline for the ransom happened to be on the same date (almost right down to the minute) as the episode's scheduled premier. However, due to a mistake by the Australian simulcasting website, the English subtitled version was still released (and pirated) at the normal time, leading many fans to mistakenly think that the next week's episode was actually the one delayed.

* OffModel: Karma in chapter 70 and Kayano in chapter 129 both have panels where their left hands have thumbs on the wrong side.
