"Christmas Special: Horrible Christmas" 17 December 2010
Christmas is a time for good will, family and presents. However, in Horrible Histories it's a time for farting jesters from Henry II, Christmas cards full of bacon and a Christmas dinner confiscated by Oliver Cromwell, and William the Conqueror's soldiers, believing that appreciators were attackers on Christmas Day, burned Westminster Abbey. Merry Christmas, Horrible Histories style! Viewers tuning in will discover that William the Conqueror was crowned on Christmas Day 1066 but, when the congregation cheered, his soldiers thought it was a riot and burned down Westminster Abbey. Other tales include that of King Henry II's famous medieval jester, Roland the Farter, the man whose sole job was to break wind on Christmas Day. The show also explores some weird Victorian Christmas cards, which could include anything from a slice of bacon to a dead mouse.
