They are bull****. Nothing paranormal about them. Why the dead would want to communicate with us? Oh, wait. They can't communicate with us cause they are DEAD.
Edit: Actually, I'll elaborate on that. Ouija boards do work, but not via some mystical mechanism, it's a simple unconscious movement of a participator's hand that conforms to their expectations.
I used a ouijia board once with a group of friends. We asked the dead who should go get some beer and the answer was Murray. Though it wasn't the dead just 4/5 (the last 1 was Murray) of us moving the thing around. It showed excellent teamwork on the fly and you can play some decent pranks with one but other then that it is total bull****.

Reminds me of George Carlin.
Seriously, you know, sometimes I believe in ghosts and all, but why the hell would they want anything to do with us?
If I were a ghost, I'd just mess with people's **** and run off giggling.
They bring in a Ouija board to appeal to me? I'll manipulate it to "kill yourself, douchebag."
