Calling Nichijou a moe anime is like calling a pug a cat. Nichijou is troll anime: it’s about the best of friends trolling each other.
A good analogy (and not a sports one, natch). I think there was more to it, as KyotoAni persistently tried to demonstrate uglier faces of jerks that are everywhere (such as the arcade owner). Still, friendly trolling definitely was the spine. And then, debauchery, and plain crazy, too. It all was impressive, but I loved when the pug went cat, like ep.14 (Nano going to school).
