Ah, Endy, glad that you are still here and feeling purplish. I think that I just coined a word.
O'George may know this bit of history:
Halloween first was celebrated in the United States in the 1840s, when Irish Catholics, fleeing from the potato famine, brought Halloween customs with them to America. The tradition of carving jack-o'-lanterns originated with Irish children who first carved out the centers of rutabagas, turnips and potatoes and placed candles inside. This symbolized a mythical ghost doomed to walk the earth forever because he had angered both God and the devil. The new Americans found that pumpkins made even better jack-o'-lanterns than the other items they had used in Ireland.
Great video featuring the banshee, who by contrast, is a woman.
