Woo hoo! I have some (um, you-know-what-type) episodes on DVD. My favorite was the one where the parents made up the story about the Grither, an evil monster that lives at the North Pole, to scare their kids on Christmas Eve, and just as they're trying to comfort the children and tell them that it was just a story, the Grither's hands burst through the window and snap the parents' necks. What an absolutely delightful, f*cked up Christmas tale. And Six from Blossom was one of the kids.
I also love the one with Eileen Heckart. And the one where Phyllis Diller and (I think it was Laurence Tierney?) pretended to be exorcists to get money and ended up possessed themselves.
The one where the girl was stuck on the train with all the dead people used to scare the crap out of me as a kid, though. That and the one with a very young Alison Sweeney as a kid who would say goodbye to people as a sign before they died.
