Liked it almost as much as the third one
I'd added the "Possessed II" one to my favorites, and on rewatching it again I realized it might actually be funnier if the possessed Mary looked a little more like the non-possessed one. The way you had her with that trademark "Mary Poppin's hat" in this episode was just about perfect. I love it either way, but it's just a thought. Keep 'em coming! :-)
