Carolyn the Undead

Still the most shocking development in House of Dark Shadows:  though our beloved Nancy Barrett found herself on the wrong (or right, depending on your POV) end of Cousin Barnabas' fangs in most of her incarnations on DS, she never succumbed to vampiritis on the daytime serial.  So it was with a strange combination of horror and titillation (anyone can become a vampire in this bizarro world!  anyone!) that we watched vivacious Carolyn lower herself to attempted cousin chomping.  It's still one of the most effective scenes in 1970s horror cinema, right up there with anything Hammer ever did, even in their heyday.
