It is almost a reverse dictionary query for "Jack O'Lantern" and his legend, which is another version of the one who mocks the Devil and when he dies they do not want him even in Hell not in Paradise; so I'm going to skip that story. But I do comment that his lamp with an eternal ember was made of hollowed-out turnip, common vegetable in his native Ireland. Irish immigrants did not find abundance of turnips in North America, but pumpkins, so they followed their tradition of remembering Jack with a candle now inside this berry. As american cultural penetration was the one who popularized Halloween, we know the pumpkin version more than that of turnip.
