MarkWHO42's Universe gets into the Halloween mood this week by talking about the scariest moments in television and movies, including Doctor Who, that made us go behind the couches (yep, that's what we call sofas on this side of the pond) during our childhood. Join Eduardo M. Freyre and Zion Quiros as they give all our tricks and treats to celebrate this spooky holiday!
