-Konata's "pochittona" when she pushes the key is famous and overused line from the
Time Bokan anime series. The skinnier bad guy (who's name is diffrent from show to show) always says that when pressing a button in the robot.
-The TV Drama Tsukasa wanted to watch (but decided to record) is
14 sai no haha (14 year old mother) series.
-Kagami says she likes shooting games, and Konata likes gal-game and RPG.
When Japanese gamers say "shooting games", we don't usually mean FPS. The old-school shoot-em-ups where you control a flying fighter, and shoot stuff off the screen like Gradius, Xebius, 1942, R-Type, and whatnot.
-The reason why the girls are laughing about Konata being a "gari" on the sushi-fortune telling, is because gari is a side-dish and not really a sushi at all.
-As some mentioned, the horror flick the girls went to see seems to be
Saw 3.
Dunno, I don't watch scary movies. I like to sleep.
-Konata's line "Buffet... it's land of women's greed" is a direct reference to a line from
ToraDora! novel series, except in there the chararcter says "Pudding in bucket" instead of buffet. Japanese refer to buffet as "Viking" style restaurant.
-The girls keep saying "that" athelete, but they are all refering to real-life sport athletes of course.
-When Kagami said this year's championship was "that" team and "this" team, she meant
Hokkaido Nippon Ham Fighters and
Chuunichi Dragons. That's why Konata asks "isn't there something like bargain sales on ham?"
-When they introduced Tsukasa, Akira starts to say "
Kamigishi Akari from
To Heart?", which Shiraishi bleeped out by yelling out Koi no Mikuru densetsu from
Suzumiya Haruhi. It's yet another joke at Tsukasa looking just like Akari of To Heart.
-Shiraishi wimpering as he mutters "I've never been hit even by my dad" is a famous and popular line by
Amuro Rei of
Mobile Suit Gundam.
-Ending song is
Kogarashi ni Dakarete, by
Koizumi Kyouko... affectionately known as "
Kyonkyon", idol singer in the 80s.
-Konata is talking about the famous
Super Mario Bros. trick in the preview of the next episode.
Where you could stomp on a turtle shell on the stairs infinitly, and get infinite 1UPs... but when you hit 129 man, it reaches a cap, and if you die even once after you reach the cap, it's game over.
