The comedy lives entirely in the space between what Tanaka refuses to do and what everyone around him desperately needs him to do. These shorts understand that the funniest thing isn't a punchline, it's watching a fundamentally unmotivated person become the immovable object that everyone else's chaos crashes into. Watch this if you want your comedy served warm and your pacing glacial, because Tanaka's refusal to hurry is the joke, and the show trusts you to laugh at the silence.
A set of seven short comedy specials released in 2016 alongside the Blu-ray and DVD editions of Tanaka-kun wa Itsumo Kedaruge. They were packaged with those home video volumes, and like the main series they are light slice-of-life comedy.
