What it is: An underappreciated goofy short comedy 
series available dirt cheap on DVD from Bandai.  
It's about three kids and the various ghosts that 
haunt their school; keep an eye peeled for some 
hysterical anime and Iron Chef parodies in ep. 4.

I've seen cels from this show turn up at Nichibei 
recently, too, but it doesn't seem like too many 
dealers carry it (not popular enough to take a risk 
on buying, I guess).  I myself wouldn't turn down a 
chance for cels of some of the spirits, 
particularly Bones and Guts...
