Lots of good stuff here. Shino helping out with the judo club, some unusual preparations for the sports festival, Takatoshi being a hero for stomping out a fly (very Obama-like, good move) and Mutsumi being used in the opening gag. Kaede also debuted, though she really only got about one scene. Plenty more episodes left, though.
However, one thing in this episode I have to commend is the art. The notepads are getting stamped with increasingly more stamps that require artificial extensions. The crayon drawing that started off Suzu's segment. And the art shifts to Shino's fantasy and the judo girl/boy love match. All very well timed and executed, turning the medium of animation itself into a storytelling tool. Always something I can appreciate.
