Bull pooties.

I have a copy of the Necronomicon right here. I got it in a small shop in Arkham, Massachusettes. It's stamped right on the back, "Property of the Yog Sothof Memorial Library. Bound pellagra humanorum by Chthulu Bindery -- 'Chthulu: Bound To Be A Better Binding'."

It's just a book -- why would you think otherwise? And a library discard at that.
