I read that in the booklet that come with the Student Counsel Saga of the remastered DVDs. In the episode note for the curry episode, Ikuhara stated that it was originally intended to air as episode 6, but since it wasn't ready in time they aired the kangaroo episode, which was intended as episode 8 instead, then aired the curry episode as 8. He also said that the kangaroo episode was meant to tie in with the following episodes.

I found that rather interesting when I first read that, and started to wonder why the episodes weren't put back into their intended order for future video releases. Maybe it would have been a little odd for those that watched the original TV broadcast, but from what I understand, Japanese TV very rarely airs reruns so wouldn't they get used to it. And for people who watched it for the first time on a video release, they would probably never know. Although I guess it can also be argued that without having read the booklet, I probably would have never known the episodes were switched. Although I did wonder why Tsuwabuki wasn't in the curry episode after being introduced in the kangaroo episode, and that recap episode that showed him spying on Nanami during the events of the episode just mystified me more since I thought that she already knew him due to the order the episodes were aired.

So knowing this I have wondered if I should started watching the episodes in this order from now on, but in the few times I've rewatched them since learning this I just couldn't be bothered. I think it's just a pain to go to the menu inbetween each episode just to watch them in the intended order. Plus they are both filler episodes with little connection to the actual plot. It may have been different if they had been discussing the result of Juri's duel in the kangaroo episode, but as it is, there just isn't much anything in either episode that makes watching them in this order confusing. What do the rest of you think about this?
