Around a week ago, Ooi Futou (大井埠頭) uploaded at Nico Nico Douga a parody video of GIRLS und PANZER, replacing much of the dialogue with dialogue from other anime (often by characters voiced by the same seiyuu); interspersing and editing together footage from other anime (e.g., Gundam, Yamato, Gunbuster, Hayate, HoiHoi-san) and live action films (e.g., Back to the Future), etc.:
【ガールズ＆パンツァー】小ネタ、没ネタ、パクリネタ臭 ぱーと死地
For whatever reason, Nishizumi Maho seems to have had the most dialogue replaced and added in this parody video with dialogue by characters her seiyuu Tanaka Rie has voiced in other anime, such as Suigintou from Rozen Maiden, Maria from Hayate the Combat Butler, Minna-Dietlinde Wilcke from Strike Witches, and Combat-san from Ichigeki Sacchu! HoiHoi-san.
Well, at least Maho expresses her real feelings for Miho.
