This makes me scared to think what Kou might be like for Detention.

Although Kou sets up a small classroom, the only people who come to ‘learn’ (save for the ones that come to watch tauntingly) are the Iron Brothers – and all attempts to teach them anything don’t go over well. Kou tries to teach them about ‘common sense’ first – to little avail – and eventually decides to have a ‘fun’ science lesson instead. Which is soon interrupted by Stella, who seems a little angry about Kou ‘taking away’ her ‘friends’.
A conversation with P-ko which eventually turns to the Mayor (and his amazing changeable hair)soon causes Kou to question exactly what ‘common sense’ is itself.

I wonder where Hoshi got that uniform, and why he'd go through all the effort to wear it.

Favourite Nino cap of the episode.

They mistook Kou's 'science' for supernatural powers, hence the mask. This part actually made me snort.

I didn't find Stella that great before, but she's pretty awesomely hilarious like this, when her voice goes all deep.

Arakawa’s forte is visual and situational humour, and SHAFT do this very well. It is not, sadly, as good as verbal and dialogue-based humour, and these parts never seem to work very well when animated, either. There are some moments pulled off quite well, but there were quite a lot of parts in this episode that just drag on too long with banal and only mildly amusing conversation – which is something disappointing when this series can otherwise be so brilliant.
The whole classroom segment was great, though; full of the type of humour the show excels at whilst keeping itself relatively low-key. (Until, at least, Stella arrived on the scene; a part I found quite brilliant with her mafia-boss getup and slurred voice) There was also just something so very nice and homely about seeing Kou as a teacher – mostly due to his Zetsubou-sensei voice. From the way his class was going, I actually expected him to do a ‘zetsuboushita!’ about the students right there.
P-ko is adorable, and the idea of her driving is terrifyingly funny and all, but this scene just didn’t work for me. I think I would appreciate the dialogue scenes more if SHAFT could find a way to ‘spice them up’ rather than continually showing close-ups of Kou’s blinking eye. It’s really…dumb. I know they did this in Bakemonogatari with the dialogue-heavy scenes but they also used a lot of alternating angle shots to at least keep things visually interesting. Arakawa doesn’t have quite this variety, and I always feel that these scenes would be funnier to me in manga format. On the plus side, the whole conversation was a build-up to the hilarious moment with the Mayor’s changeable hair.

She actually looks cute here...

Sister with this pretty sparkly background just looks so wrong.

I really do love the way P-ko's hair is coloured. And her hair in general.

The funny thing is, I know a guy who looks just like this only without the kappa-ness. I'm pretty sure everyone knows at least one.

I had my problems, but it was still a decent episode with some great moments. Out of 5,
