A classic, short-lived sitcom from the early 60s about a typical American family, except they just happen to be classic horror movie figures. The husband/father was Herman, who resembled Frankenstein's monster; the wife/mother was Lily, a vampiress; their son was Eddie, a werewolf boy, Eddie's grandfather (Lily's father) was Grandpa, the original Count Dracula (my avatar this year)... then their was Herman and Lily's niece Marilyn, who was a normal, everyday girl, yet to them, she was the "unfortunate" one in the family.
