ESL theme:Jack-o'-lantern

A modern jack o' lantern is typically a carved pumpkin, although originally typically large turnips.
 It is associated chiefly with the holiday of Samhain and halloween and was named after the phenomenon of strange light flickering over peat bogs, called ignis fatuus or jack o' lantern.
 In a jack o' lantern, typically the top is cut off, and the inside flesh then scooped out; an image, usually a monstrous face, is carved out, and the lid replaced. It is typically seen during Halloween.
