Sulverna - My kids and I happened to watch that episode of Scooby Doo on Netflicks a few weeks ago. I can't remember the exact name of it but I know Witch was in the title. At first I was like "oh brother, here we go." But I was pleasantly surprised by it. I hadn't heard Lisa Simpson is Wiccan but then again I don't allow my kids to watch that show. There used to be a Druid website years ago that detailed the similiarities between the Smurfs and Druidism. I will have to go try to find it now. I think it is great that we are getting little hints of exposure in cartoons. I think it helps children being raised Wiccan or Pagan to feel like their religion is being accepted a little by the media.
On a side note, I see you are in Ohio. I am in Cincinnati!
