Sket Dance

The Sket Dance watch order is about as easy as long-running series get: the full 77-episode run, Episodes 1-77, followed by a single OVA. Start at Episode 1 and watch straight through the entire TV series, which follows the Sket-dan club's mix of comedy, drama, and slice-of-life antics as one continuous run. Once you've reached Episode 77, cap things off with the Sket Dance OVA, a standalone extra meant to be watched after the main series. There are no movies, no branching seasons, and nothing to reorder — just the show in numbered sequence and then the OVA. This 2011 Tatsunoko Production adaptation rewards watching in order, since the cast and running gags build over its long episode count. If you were unsure where to start or whether extra content existed, that's the complete picture: 77 episodes plus one OVA at the end.
