You may have heard of Haruhi spinoff/parody manga 涼宮ハルヒちゃんの憂鬱 / The Melancholy of Suzumiya Haruhi-chan (see below), by ぷよ / Puyo, a superb and most amusing manga using the SOS-dan, but eschewing the ridiculous story and serious elements of the original in favour of parody and absurdity (famously Nagato is a determined erogamer, for example).
It has gained great popularity, and even the authors of the original have stated that they should probably made the main story like it; the popularity has allowed an anime adaptation, just announced.
However, in something of a twist the anime will be distributed online via YouTube (Nico must be weeping), rather than be a conventional anime. Quite disappointing; really it is better than the original and deserves a full series, though maybe one will be forthcoming later. At any rate, even a YouTube anime may be better than none, perhaps.
In case you’re not familiar with the manga in question (it comes highly recommended):
