And, it's a sad day in the neighborhood.

I think it was Fred Rogers who taught me the concept of "other worlds." There was his, and then there was the world of King Friday.

My favorites episodes of Mr. Rogers were the ones where they met Lou Ferrigno, and he showed Fred and the kids at home how he turned into the Incredible Hulk. I also liked the one where they met the lady who played the Wicked Witch of the West in the Wizard of Oz.
