What can be said about these? Are you full of sugar, and want to see something that makes no sense - but shown at high speed?
Intended as what? A recap of the series? A quick reminder? A teaser of what is to come? Extra scenes for the true fans?
Who knows - but they're always fun.
Might as well say it here: AzumangaDaioh is kind of fun to watch with the fast-forward button pressed down. The voices are even squeakier and on my computer it wasn't so fast that I couldn't read the subs.
