......This late mid sixties show has been poping up in my mind lately. I remember it always opened with a skulls head moving side to side with a sort of toupee on then it was snatched from it's head .....anyway iwas very young and the show scared the pants off me ........oh the parenting skills of yester year. Anyhow does anyone remember the prog? you'd have to be knocking on 50 to remember.
