Before there was FLCL, before there was Excel Saga, the undisputed champion for out of control funny anime was All Purpose Cultural Cat Girl Nuku Nuku. Although "Nuku Nuku DASH!" is a strangely serious take on the story, with some weird changes to continuity, Nuku Nuku TV carries on the tradition of belly laughs started by the original 1992 OAV series.
This is anime as if it was done by Mel Brooks and/or Zucker Abrams and Zucker. You have an andro-robot with the brain of a cat who is trying desperately to act human. You have a mad scientist and his super-smart, sarcastic son. You have a corporate president who has watched too much Anime and Sci-Fi movies and now fancies himself an Evil Genius. And you have a high-school class filled with the oddest group of misfits you're likely to see this side of "Square Pegs."
Anime cliches get absolutely no mercy here, nor do quirks of Japanese Pop Culture. Transforming robots, fighting Mechas, earnest psychic girls, mad scientists, scheming villains, heroes who fight for love and justice and say the most bizarre things while doing so...they all get savaged here. Add to this a little girl with the weirdest pets, and the weirdest karaoke contest ever, and you have an anime that's a must-get.
This is even a title you can share with the whole family. Nothing the least bit suggestive here, perhaps a mild bit of cussing in the subtitles but nothing that wouldn't get a PG or PG-13. Any kid who can read well enough to read the subtitles should have fun with this. I didn't watch the dub all the way through because I really don't like it, but the subbed version is lots of fun.
