I was close to dropping Nichijou after the first epsiode - you could say it's Azumanga on crack, but I didn't like the cast nearly as much as Azumanga or Lucky Star's. But somehow, episode after episode, it manages to grow on me all the same - last week's principal doing a German suplex on a deer was one of the funniest scenes I've seen this season, and this week we get the epic wooden cube drama at the beginning and Wakamoto Norio at the end. Got to think they could have done more with Wakamoto-sama's talents in the preview, but still a solid episode.
Minion #6 figures out which way the wind is blowing first.
If it's voiced by Wakamoto Norio, it's an ancient superweapon.
