The Ouija has a long and rather interesting history.  Here are a couple of accounts to check out:

The History of the Ouija Board
The Infamous evil Ouija Board
Apparently, all the bad press about the Ouija came out when the movie “The Exorcist” was released, back in the 1970’s.  It also sounds like that’s when the Christian fundamentalists jumped on the bandwagon.

At least I now know where to put the blame, as if that would help…..  😐
