An OVA (original video animation) to Sket Dance was released a few days back. It is a nice continuation to the whopping original 77 episode series, in case you didn't get your fill.

This OVA starts where the plot left off at Episode 77 and is a nice "re-visiting of the series. The exchange at the beginning with the cast breaking the fourth wall is quite hilarious.

If you have not been introduced to the series I highly recommend it. Although it is a lengthy 77 episode series, it has great comedy and slice-of-life elements. If I am not mistaken, it may the longest anime in the "slice-of-life" category but I could be wrong on that point.
