Like Jennifer said, if you come across some kind of everyday item that:
a. is indestructible
b. does something weird
and/or
c. gives you the willies,

O. If you come across one, get it to Jennifer pronto. Or me, if you want.
I guess I can return them to the Room. I don't want to say much more, because frankly, I don't really know how many of you belong to cabals, and I don't particularly want to be acquired.
