Supernatural Collective Nouns

Isn't it amazing what you can find floating around on the Web?

I thought this list was awesome!

Some of my favorite terms include: "a rumpus of phantoms," "a cackle of mad scientists," "an industry of villains," "a caper of mutants," "a rage of orcs," "a lunacy of werewolves," "a dastardly of manticores," "a rustle of reapers," and "a vexation of zombies." =)

I'd love to know more details about the "All Entries Verified" claim in the lower right corner...
