Lucky Star OVA

During the MMORPG sequence Kuroi-sensei asks, why Kagami is playing the game. Konata explains that the screenplay for the anime, which promoted the game, was written by the creator of one of Kagami's favorite light novels. This refers to 'The Tower of Druaga: the Aegis of Uruk', which was produced to promote the MMORPG 'The Tower of Druaga: the Recovery of BABYLIM'. The Screenplay for the anime was written by Shoji Gatoh, creator of the 'Full Metal Panic!' novels, which Kagami has been seen reading during the original series.

At ~ 11:25, the decisive victory pose is the last pose of the suzumiya haruhi Ending.

The magician costume Konata starts wearing at ~ 13:50 is the same Yuki from Suzumiya Haruhi wore during the cultural festival

When Konata and Kagami are driving to the ball, the character Konata changes Kagami into after the shrine maiden is Tohsaka Rin from Fate/Stay night

At around 30:29, when Konata's cellphone rings, the ring tone was "Koi no Mikuru Densetsu" from The Melancholy of Suzumiya Haruhi

At 4:00, Patricia shouts the punchline "Zetsubou shita!" (I'm in despair!) from Sayonara Zetsubou Sensei

At about 21:40, Konata tries to have her teammates perform the Jet Stream Attack, trade move of the Black Tri-Stars from the first Gundam series (it is also seen in Gundam SEED Destiny). The move consists of three DOMs lining up to close the enemy at high speed and then attacking simultaneously with two ranged attacks and one melee attack.

The last costume Kagami gets changed into by Konata is that of Hatsune Miku, mascot of Yamaha's singing synthesizer software Vocaloid2 and famous character in moe subculture.

At 5:20, Yutaka sings about the dog Cherry being cute; the melody she sings is from "Santa Claus is coming to town".

At around the 9:10 mark, the game franchise that Konata and Nanako discuss is .hack.

At 3:28, the song that Konata sings is "Sasoriza no Onna" (Scorpio Woman), a mega-hit of the early 70s by Japanese singer Mikawa Ken'ichi.

At 22:43, Konata uses the line "dakedo namida ga dechau... onna no ko damon!" ("but tears are coming out... I'm just a girl, after all!") This line was originally spoken during the opening sequence of the classic volleyball anime Attack No. 1 (by its main character, Ayuhara Kozue). In fact, the song that plays in the background while Konata is doing her impersonation is the opening theme of Attack No. 1 (sung here by Fukuhara Kaori, the seiyuu of Hiiragi Tsukasa).

At 23:43, Misao's thumbs up "guuu" is a parody of the trademark gestures of popular Japanese comedian Edo Harumi.

At 25:09 and 28:40, Konata's line "ten wa warera wo mihanashita!" ("the heavens have abandoned us!") is lifted straight out of the 1977 Toho film "Hakkoudasan" (Hakkouda Mountain), a movie about survival under extreme conditions that was based on a true story. In the film, the line is spoken by Captain Kanda, who was played by famous period drama actor Kitaooji Kin'ya.

At 28:26, Konata says to Kagami: "ii ka? Ano shichousei ga zujou ni ochiru hi made seippai ikirou!" ("Hear me? Until the day the star of death falls upon you, live to your fullest!") This line was originally spoken by Rei to Mamiya in the anime Hokuto no Ken (Fist of the North Star).

At 33:15, Konata calls Miyuki "ginga no utahime" (galactic songstress) and says that "Motteke" is now different. This is a reference to Macross Frontier, in which Endou Aya (Miyuki's seiyuu) plays Sheryl Nome. One of Sheryl's songs, "Iteza☆Gogo Kuji Don't be late" ("Sagittarius 9PM Don't Be Late") has the line "motteke ryuusei chirashite date", which certainly features different wording compared to "Motteke! Sailor Fuku" (the opening theme of Lucky Star TV).

At 33:23, the frogs brought out by Minoru resemble Keroro and Tamama from Keroro Gunsou (Sergeant Frog) and are, in fact, voiced by Watanabe Kumiko and Kozakura Etsuko, the seiyuu of Keroro and Tamama, respectively.

At 32:57, Minoru proclaims "koko made no serifu no kazu... watashi wa zero! Watashi wa kaetta kita!", which can be read two ways: "the number of lines so far... I've had zero! I'm finally back!" (a lamentation about Minoru's lack of lines in the OVA) or "the number of lines so far... I am Zero! I have returned!" (an obvious reference to Code Geass: Hangyaku no Lelouch R2). Konata's reply "omae wo borozoukin no you ni tsukatte yaru!" ("I'm going to use you like a tattered rag!") is also from Code Geass: Hangyaku no Lelouch R2.

In the segment that begins at 34:22, Anizawa Meito/Tencho appears to be wearing a Gold Cloth (from Saint Seiya) underneath his apron.

At 34:40, the weapons that Anizawa Meito/Tencho puts up for sale are all legendary weapons that appear in numerous anime and games (a large number of them appear in the Fate franchise, and Seki Tomokazu -- Tencho's seiyuu -- voices Gilgamesh, a character who can summon legendary weapons at will, in Fate/Stay Night). From top to bottom, the weapons are: Excalibur, Caliburn, Durandal, Laevateinn, Dainslef, Gram, Claiomh Solais, Caladbolg, Fragarach, and Hrunting.

The theme song of the Lucky Channel segment in this OVA is an Akira/Minoru version of "Ai wo Torimodose" ("Take Back the Love"), the first opening theme of the Hokuto no Ken (Fist of the North Star) anime.

At 35:50, the melody that Minoru is singing "wa wa wa~" to is from the song "Roppongi ~Giroppon~" by Japanese singer Nezumi-senpai. Minoru's outfit is, in fact, an imitation of Nezumi-senpai, a fact alluded to when Minoru later says that his is a popular "senpai" look.

At 8:34, the "meat" action used by Tsukasa is a reference to Monster Hunter.

At 11:12, Konata makes a remark about "Lodoss tabletalk." She's referring to the Dungeons & Dragons campaign replays published by Group SNE (classified as tabletalk role-playing games/TRPGs in Japan) that later became the basis for the Record of Lodoss Wars anime/game franchise.

The Aegis of Pizza-la used by Nanako at 12:12 bears the logo of Pizza-la, which not only exists in real life but is, in fact, Japan's #1 delivery pizza chain. The Aegis of Pizza-la itself exists in exactly the same capacity indicated in the anime -- as an exclusive limited item for The Tower of Druaga MMORPG obtainable only from Pizza-la.

The programs being watched by Kagami around the 13:00 mark are the variety show "Sanma no Karakuri TV" and "Gyouretsu no Dekiru Houritsu Soudansha", an educational program about law presented in a variety show format.

The move used by Nanako at 16:51 to win her match is a triangle choke, which is a submission maneuver often used effectively in real-life mixed martial arts.

At 24:11, Konata says to call her "Kasukabe no Majo" ("the witch of Kasukabe") after making a rolling dig. This is a reference to the Unitika Kaidzuka Women's Volleyball team, which achieved a 22-match winning streak on an European tour in 1961. The team was retained in its entirety to represent Japan in the 1964 Tokyo Olympics, where it won a gold medal and earned the nickname "The Oriental Witches" ("Touyo no Majo" in Japanese) from foreign media. Konata substitutes "Kasukabe" in place of the word "touyo" ("oriental") because Lucky Star is set in the town of Kasukabe in Saitama Prefecture.

The logo used at the start of the OVA (which features a shot of Konata in profile against a blue background) is a parody of the Totoro logo commonly found at the start of Studio Ghibli films.

At 12:26, Konata holds up a bowl of ikura-don (salmon roe noodles). This is another exclusive item for the Tower of Druaga MMORPG, obtainable only by participating in the game's "Ikura-don Tabemakuri Campaign" promotion.

At 18:17, Misao says "kenka yohou no jikan da yo" ("it's time to forecast the fight"). This is the name of Hiiragi Kagami's character image song.

At 1:30, the episode title "JK" stands for "joshikousei" ("high school girls").

At 19:37, Tsukasa's "po popopopo..." line is also a reference to the song "Roppongi ~Giroppon~" by Nezumi-senpai.

The clock-ticking sound effect heard around 19:38 is a reference to the American TV drama "24".

At 24:31, Tsukasa says "butsukatteru yanaikai~" ("ain't it no fun to crash into that...") upon crashing into the net. This is a punch line often used by the manzai comedy duo Hige Danshaku.

At 25:55, Konata answers a question about why she felt like climbing the mountain with "soko ni yama ga aru kara" ("because the mountain is there"). This is the translated version of famous English mountaineer George Mallory's response to a question about why he wanted to climb Mount Everest: "because it is there."

At 27:14 and 30:17, Konata calls Miyuki "Miwiki-san". She's comparing Miyuki's capacity as a know-it-all to the popular web encyclopedia Wikipedia.

At 30:30, Konata answers her phone with "hai, Sazae de..." ("hello, this is Sazae..."). This is a reference to the anime/manga Sazae-san.

The entire segment that begins at 31:50 is done in the style of the anime/manga Sayonara Zetsubou-Sensei.

Starting at 32:45, Kagami and Konata have an exchange about a black cat, which Kagami says "is not a witch" and Konata says "won't take your soul." This is a reference to the cat witch Blair from Soul Eater, who happens to be voiced by Katou Emiri, Kagami's seiyuu.

At 34:11, Minoru shows up dressed like Mujaki, the dream demon from Urusei Yatsura: Beautiful Dreamer.

At 34:56, Anizawa Meito/Tencho shouts "ne-AFK ka yo~!!!" ("she's doing a sleep-AFK!!!") as he realizes what's going on. This is a reference to some MMORPG players' habit of leaving the game running while they sleep, thereby being AFK/Away From the Keyboard for the whole night.

At 41:25, Minoru's pose and voice comprise an impersonation of Japanese singer/songwriter/musician/personality DAIGO.

The "Yaranai ka" necktie worn by Shiraishi Minoru during the ending sequence is an obscure reference to the explicit yaoi manga Kusomiso Technic.

The "sta~ff~!" call used by Shiraishi Minoru at 39:18 is a signature gag used by Japanese comedian Kano Eikou.

At around 10'42", Tsukasa doesn't understand the word "sute" (for "stats") used by Konata, and thus, she wonders if her friend meant "Sutepuri"... which looks like a reference to the manga & anime "Scrapped Princess" ("sutepuri" is its abbreviated name).

At 19:32, the censored "undo" spell Kagami reluctantly shouts in her dream is: "Konata to gattai shitai!" ("I want to unite with Konata!") -- a close parody of "Anata to gattai shitai!" ("I want to unite with you!"). The latter was a highly-promoted catchphrase from the TV series Genesis of Aquarion, in which flying mechs and their human pilots literally merge into one gigantic entity. This joke is lifted from a karaoke setting in an earlier Lucky Star manga. In that version, Konata embarrasses Kagami with a line from the Aquarion theme song about having "loved you for 12,000 years". Following the same anata/Konata confusion, Konata takes advantage of Kagami's slip by gleefully mauling her.

At 21:15, the "super ultra miracle eccentric special serve" used by Konata is a move that first appeared in episode 6 of Suzumiya Haruhi no Yuutsu, where it was used by Suzumiya Haruhi (voiced by Hirano Aya, Konata's seiyuu) in table tennis.
