After weeks of inaction... what has he been concocting in his lair? What nugget of wisdom has he been cooking up in his kitchen of doom? The tension mounts.

A video of a Super Mario level where the sound effects match the opening track of cult anime series 'The Melancholy of Suzumiya Haruhi'. Clearly my mental faculties are leaving me.

Update: It's actually a medley of anime music, 'Hare Hare Yukai' was just the only one I could recognize (or care about - Suzumiya Haruhi ftw).

Update: OK, found out a bit more about this. 1 - Kotaku posted this early May. But I am not going to read Kotaku, so meh. At least I blogged it before Boing Boing. 2 - This is the 'Nico Nico Medley' (or 'Nico Nico Douga'), a medley created on or for Japanese YouTube-ish site Nicovideo.jp. As far as I can tell it is a medley of anime themes by hard-core anime fans. The medley appears to be quite popular in the otaku underground, there is even a blog about its various manifestations... More about Nicovideo.jp and related subcultures here (although their instructions for registering sadly do not seem to be up to date).
