Student Council's Discretion (TV)

The title of the second ending theme (first heard in episode two) translates to "Up Up Down Down Left Right Left Right B A", which is the classic Konami Code, used for video game cheats.

The game Mafuyu Shiina plays is a game named Monster Hunter.

In episode 1 around 0:56, the characters make a reference to Dragon Ball, collecting 7 balls of whatnot and powering up. Another reference was made about DB: Evolution around 1:45.

To elaborate on the two Haruhi references, in episode 1, at 1:50, Kurimu wonders how to write the word "yuuutsu" (melancholy) after writing the word "Suzumiya" on the board (for "Suzumiya Haruhi no Yuuutsu" = The Melancholy of Haruhi Suzumiya), saying that everyone would watch the show if it was called that. What's ironic is that the whole debate on what the anime's title should be was because they didn't like how the anime was named after the first novel of the series, yet both seasons of The Melancholy of Haruhi Suzumiya (both having the same name) were named after the first novel of the Haruhi series. On the second reference, Ken recites a phrase that Haruhi used during her High School introduction, only to be interrupted by Kurimu as she puts a sign that says "kinsokujikou" (classified information), which is a phrase that Mikuru Asahina (also from the Haruhi series) says on many occasions, in front of Ken's face.

In episode 1, at 0:18, the website they are referring to is a reference of Amazon.com.

In episode 1, at 19:32, they mentioned the approval of castanets for the light-music club ("kei-on bu"). This is a reference to K-ON!, when Yui thought that the light-music club would play "easy" instruments such as a castanet.

In episode 1, at 8:18, Kurimu says that Ken Sugisaki is not one of the popular main characters, but is more like the main character's best friend that is used only for jokes. Then, she writes the kanji for "Sunohara" on the board and says to pronounce it as "Sugisaki", but Ken corrects her as says the kanji should be the ones for "Okazaki". This is a reference to Clannad, where Okazaki is the main male protagonist who is loved by all of the girls, while Sunohara is Okazaki's best friend (that is used only for laughs).

In episode 1 around 1:35, the "survive" title they used is similar to the style used in Kaiji
