I've left Macchiko sensei on as a trigger (auto-search / auto-download) on SHARE for the past few days, here are some of the clips I found:

Machiko stripping for a shower (happens quite frequently, and more often than not she'll end up chasing someone out of the shower room naked, not realizing she's undressed until halfway across campus):

This is kinda an experiment, I am not sure if YouTube will allow me to keep these clips et all up. If they don't get deleted, I'll try to start uploading some of the episodes as I find them.
Edit: So much for that, they're ALREADY being deleted:
