We’ve all suffered the Twelve Days of Christmas carol ad nauseam, but have you ever stopped to consider the history of this excessively generous barrage of gift giving? And could you remember the full gift register of disparate live poultry and hired performers, in reverse, under pressure that if you forfeit it could result in a lingering, beery pash from your druncle? This silly season it’s not all swans, lords a leaping and gold rings; get those chestnuts roasting on an open fire and prepare yourself for a jolly visit by three creepy, merrymaking friends disguised in festive-yet-ghoulish pillowcase masks.
