At this time of the year, newspapers are always on the look-out for a story which will provide them with a Halloween headline. So when the Daily Mail reported that 58 year old presenter Kirsty Wark ended the late-night BBC current affairs TV programme Newsnight by joining 10 dancers to perform part of the routine to Michael Jackson's hit Thriller, the headline read: 'The Wark-ing Dead', a play on the American horror series The Walking Dead which is shown on Channel 5.
