Episode 17 is out by a number of groups.

Shiranui gets more and more pissed at being paraded around as the queen of the delinquents, and Mawari just keeps more fervently blowing her little whistle. Every episode, I think, "These characters can't possibly get any more insane and stupid." Yet, every successive episode, they just keep getting worse. This episode didn't disappoint at all.

I love it.

(As a side note to episode 15, we had to have realized the Iinchou had a dynamite body and face. It wouldn't be cliche enough otherwise.)
