Halloween is relatively young as far as holidays are concerned, but by the mid-20th century it was so popular with adults and kids alike that everyone agreed they couldn't live without a night of costumed trick-or-treating.
But over the decades Halloween has become virtually unrecognizable, and much more terrifying...
In the beginning Halloween costumes were simple and homemade, but as the holiday became more popular so did the idea of buying a licensed costume off the rack, and then some adults started buying off the wrong rack.
Soon the madness spread to other Halloween traditions, as simple and smile inducing gave way to complex depravity, and the world was exposed to the horror of a jack-o'-lantern giving birth.
But despite the changes Halloween is still pretty much the same as it ever was, only these days people tend to show a lot more skin.
