Put on your Christmas socks, make yourself a turkey sandwich, and clear a space for the whole family in front of the telly because Ant and Dec will be opening their doors and inviting you in for mulled wine and a big barrel of pre-scripted laughs. Set inside Santa's Cabin, complete with roaring fire, stockings and a talking moose head, and filmed in front of a studio audience, the boys will welcome a whole host of showbiz friends to join in the celebrations. Donning their Christmas jumpers, Ant and Dec will be in full festive mood as they welcome special guests, including pop legend/their golfing buddie Robbie Williams. Britain's Got Talent judges Piers Morgan and Amanda Holden will go head to head in some traditional Christmas party games and X Factor winner Alexandra Burke will be performing the Christmas song, All I Want For Christmas Is you. You can, if you wish, consider this more of a warning to avoid than a recommendation. If you want to see how it used to be done, switch to BBC2 at 9.10pm for The Morecombe and Wise Christmas Special. Expect festive fun from 1973, with guests Vanessa Redgrave, Hannah Gordon, Rudolf Nureyev, Laurence Olivier and Andre Previn, all proving they are game for a laugh.
