What's the point of dressing up on Halloween? To frighten the dead, people originally wore animal skins and heads.
It was anticipated that roaming spirits would mistake strangely dressed people for spirits and let them go. Nowadays, Halloween costumes aren't quite as gory as they once were.
Pumpkin carving on Halloween—why? The first Halloween tradition was to carve turnips. The custom originated with the story of Stingy Jack.
On the condition that Jack would never go to Hell, he captured the Devil. Unfortunately for Jack, he found out after he passed away that Heaven was off limits to him because of his shady transactions in life.
He became a ghost forever. The Devil sent him a chunk of burning coal in a turnip to light his journey. Because pumpkins were more affordable than turnips, they were used when Irish immigrants brought the Jack O'Lantern tradition to America.
