Jack-O-Lanterns have been around for centuries and probably originated from on old Irish Folktale about Jack who was pretty much a jerk when he was alive so when he died he was condemned to walk the earth with a lantern and that creeped the townsfolk out so they carved scary faces into turnips, potatoes and pumpkins, lit them up with candles, put them outside their houses and tried to scare old wandering Jack away with them.
