One story about Jack, an Irishman, who was not allowed into He**en because he was stingy with his money. So he was sent to hell. But down there he played tricks on the Devil (Satan), so he was kicked out of Hell and made to walk the earth forever carrying a lantern.
Well, Irish children made Jacks lanterns on October 31st from a large potato or turnip, hollowed out with the sides h**ing holes and lit by little candles inside. And Irish children would carry them as they went from house to house begging for food for the village Halloween festival that honored the Druid god Muck Olla. The Irish name for these lanterns was Jack with the lantern or Jack of the lantern,
