im not going to get in to voice casting im taking about the genreal content of the Show
the sheer amount of Culture references in Lucky star make no sense to 90% of western anime fandom

When Konata tells the story of how she saved Tsukasa from an evil foreigner, the video of her beating up the foreigner shows her using the Tatsumi Senpuu Kyaku (Ryu and Ken's special move) on a Foreigner who looks like Street Fighter 2's Guile in Ryu's Japan Stage from the same game. Also the Street Fighter 2 Interface is used for this scene as well.
- The ending theme sung by Konata is the opening from an old 1976 Metal Hero Series called Uchū Tetsujin Kyodain.
-The newspaper article Kagami was reading, is lifted from the Yasuyoshi Kobayashi case. Kobayashi kidnapped and held a girl in confinement with a dog leash on her. He confessed to wanting to keep her as his slave.
His nickname among some people was "prince Kobayashi", due to his looks. On Internet, many referred to him as "confining prince".
The newspaper Kagami is reading says "confining princess", as a reference to this incident.
-Many of the stores you see in the show are slightly modefied names of stores near the Kasukabe train station.
-The way Shiraishi calls out the next episode preview is mimicking how the popular cartoon series Sazae-san introduces the previews.
he two-handed heart gesture the girls made during the OP dance is a signature move for Morning Musume, requently made by two of the "cute" members, Michishige Sayumi and Kusumi Koharu. The gesture is also part of Kusumi Koharu's PV dance for "Balalaika", the OP of the extremely popular young girl's anime, "Kirarin Revolution".
