Sayonara, Zetsubou-sensei/Shout Out

"Man: Just who is Ki-- Light: I did it."
 * SHAFT's famous quotations on the blackboard and Harumi's fangirlisms are the main culprits, but there are also stuffed toy characters and dances from several shows, as well as split-second references to other anime, games, or general pop culture.
 * Partial listing of the blackboard shout-outs, subject to change:
 * Tengen Toppa Gurren Lagann: "Use your (moe) drill to break through the heavens!" "Believe in the you who believes in you."
 * This doubles up as a reference to Lucky Star's Nintendo DS game: Lucky Star: Moe Drill. (It's Brain Age-like)
 * Azumanga Daioh: "Hang in there, Tomo-chan"
 * One Piece: "Zoro x San"
 * Code Geass: "ZEROOOOO!" and "I am not Orange!"
 * Can't remember the exact wording, but once the blackboard featured a shoutout to the guy-on-guy Shotacon Hentai Boku no Pico. Seriously.
 * There's a picture of Pico on the bulletin board that turns into Chico and then Coco later on, during the scene where Kiri offers to show Majiru her swimsuit, no less.
 * Yet another blackboard gag referenced, of all things, Sylar and Hiro from Heroes.
 * In Zan there's a caricature of Nozomu in the art style of Bakemonogatari's next episode previews.
 * "The monk who leapt trough time" is obviously a reference to The Girl Who Leapt Through Time.
 * UNINSTALL
 * In one of the first episodes: "Screw you guys, I'm going home!"
 * Dragonball Z: Not a blackboard shoutout, but when Itoshiki is bewailing all the significant historical landmarks that were dwarfed by greater ones, many examples appear in the background; one of them is "Saiyan's strength / Krillin's strength"
 * Matoi and Nozomu perform the fusion dance halfway through episode 3.
 * And Goku and Vegeta spar in the background while Itoshiki monologues during the non-athletics festival in Zoku.
 * And then there's Perry's search for the Dragonballs...
 * And Masako Nozawa saying Goku's Catch Phrase, but with Meru's name.
 * In Zan 11, Ikkyu can be seen wearing a scouter, during the tinted glasses segment.
 * Zoku even has the first appearance of the Vocaloid Hatsune Miku in an anime.
 * Also recolored versions of Kaito, Rin & Len, and Meiko seen here
 * Zoku has a whole screenful or two of various characters from other shows, and during the Honey Trap segment included knockoffs of some very popular series.
 * Death Note: Light Yagami appears briefly for one page, followed by a confused Itoshiki.
 * In episode 3 of the anime, while the class is discussing the optimal angle for viewing fireworks, Sensei colapses to the ground, briefly seeing Light Yagami (a direct shout-out to the moment of ). Pan back to the students - on the blackboard behind them is written "Death NEET," an obvious reference and pun.
 * In chapter 17 of the manga, a wanted poster for Kira (with a question mark in place of the mugshot) appears.
 * There's a chapter in the manga about people saying things they'd never say as jokes (but because it's out of character, it gets taken seriously) -- included is Soichiro saying "I'm Kira".
 * The class discusses how Nozomu's "confession training" would ruin manga, leading to several imagine spots.


 * Nozomu has a Death Note himself. He uses it to keep track of people he wants to die with him.
 * Lucky Star: "You're purposely talking about stuff nobody cares about, aren't you? Like how to eat a chocolate cornet! Nobody gives a damn!" (Zoku Sayonara episode 4)
 * Not to mention the brief classroom shot with Kagami, Tsukasa and Konata in it - but in Zetsubou Sensei's animation style (Zoku Sayonara episode 9)... or the brief "Chinese bootleg" parody.
 * Or Bob Ross painting Konata. (Zoku Sayonara episode 7)
 * In the Hot Springs Episode, Unlucky Channel can be seen behind Kafuka at one point.
 * What episodes were these in?
 * In episode 9 of the first series, with Majiru's introduction as Nozomu's 'son', Matoi goes into a rage and wields what appears to be the Flaming Tessaiga.
 * G Gundam, Ultraman. Star Wars and Neon Genesis Evangelion get referenced in a big way in Episode 4 of Zoku
 * To be specific: the mask that makes her grow giant is an Ultraman mask. She dispatches the mecha in a shot for shot parallel to Asuka mutilating the MP Eva's. Abiru even hangs a lampshade on it. "Why is she speaking in German?" The last kill is a G Gundam reference (though it's called "Bakunetsu Gold Finger," she grasps the head so it's closer to the Shining Finger). Finally, she blows up the Alien spaceship with Ultraman's cross laser thing, stock footage and all.
 * Speaking of Eva references, Abiru's bandages are a mirror flip of Rei's look at her introduction. Nami's birthday party gets a Congratulations scene.
 * In episode 11 of Zoku, each of the murders is a Shout-Out to another anime series. One features Kaere/Kaede impaled on a cross with the Lance of Longinus.
 * In episode 9 of Zoku, Ghost in The Shell gets a shout-out when Maria jumps out of the classroom window, holds her hand up as she falls, and vanishes.

 * A lock from Ace Attorney briefly appears.
 * Later on, a murder mystery spells out the names of important locations with Ace Attorney's trademark clicking sound.
 * A box of doujin labeled Genshiken appears in the classroom one day, and the table behind Itoshiki-sensei at the Comic Convention turns out to be staffed by Genshiken members as well. In Goku episode one, the Halloween cosplayers include one dressed as Ritsuko Kubel Kettenkrad. And the Tanabata chapter of the manga includes a tanzaku from someone wishing to get into "Shio University" (Genshiken's version of Chuo University).
 * Meru's "death" bed looks suspiciously like the one from Sailor Moon, including her dress.
 * During the Magical Girl opening, Meru is writing out something on her cell phone. The message? Up up, down down, left right left right B A.
 * Nozomu's defeat at the end of the sequence is a reference to the end of the Shaman King opening credits.
 * In episode 12, the practice for "soft" landing is done on an arcade-like machine. On the side in one scene, it reads "Afterburner" from the game series.
 * A Zaku tied a wish to a tree. Its wish? "To become a High Mobility Model!"
 * Part of episode 13 of Zan involves Kiri losing her blanket, and the episode section makes specific reference to the character Linus from Peanuts who is similarly known for an obsession with a blanket.

 * Tengen Toppa Gurren Lagann: Has a bunch of references in addition to blackboard gags. These include two separate scenes wherein Nozomu is punched in the face in the exact same manner as, complete with Art Shift and Punched Across the Room. In the Magical Girl parody, Nozomu's defeat mirrors . Harumi is seen with Kamina x Simon doujinshi at least twice; once at Zetsubou Sensei's funeral.
 * In the 5th Zoku episode, there is a brief picture of a parody of Eureka Seven, showing a mock Renton and typeZERO.
 * Pokémon: "Interesting anime. Boring anime. That is only the selfish perception of people. True home animation quality control managers should try to discuss their favorites."

 * In episode 8 of Zoku, Maria, Abiru and Chiri are wearing the same suits as the main characters of Cat's Eye.
 * Dr. Slump: In episode 9 of Zoku, Maria mentions that the Prime Minister riding on a "space-age Segway" doesn't look any different than Dr. Mashirito. She even brings out a blurred picture of him !
 * During Ai Kaga's introduction sequence, we can see a random moment where she's sleeping top of a red dog house, complete with Woodstock (Censored by Maedax's face) flying around. In that same introduction sequence, Nozomu, Ai, Chiri and Kafuka are having a snack at a "Ntarbucks Coffee".
