Though not specifically Halloween related, The Addams Family could nonetheless be classified as a quintessential Halloween mainstay. A totally creepy family, the Addamses were ahead of their time in that they did what they wanted and didn't care what anyone else thought. In fact, most of their adventures centered on the outside world infringing on their world. Rather than conform to society, the family always found their own way.
Today, the family is still remembered and loved. They might seem strange at first look, but they're actually more interesting and fun than so-called "normal" families. So if you happen upon their "creepy, kooky, mysterious & ooky" mansion, it's probably safe to knock on their door.
