7. "They're Coming To Get You, Barbara!" - Night of the Living Dead (1968)
Johnny and Barbara come to rural Pennsylvania for their annual visit to their father's grave. Barbara gets the creeps and Johnny teases her. There is a figure walking in the cemetery. He looks innocuous at first, but has sinister designs on Barbara. The man grabs Barbara and tries to take a munch out of her. Johnny goes to defend her but falls and cracks his head on a grave stone. Barbara flees. What makes this episode so scary is the fact that Johnny believes this man to be an ordinary guy but then the guy goes all zombie on Barbara's ass. We have witnessed the emergence of the modern day zombie and it is pant wettingly scary.
