In an inspired piece of scheduling, Channel 4 bins the Come Dine With Me repeats and dedicates the whole of Christmas Eve to Graham Linehan's honkingly funny sitcom. Set in a terrifyingly realistic man cave in the basement of a dysfunctional London company it is, according to those who know their ethernet cables from their elbows, almost a documentary.

Surrounded by empty boxes, unopened manuals, stickers and plastic desk toys, Moss (Richard Ayoade) and Roy (Chris O'Dowd, before he was Bridesmaids famous) skive, snigger, talk about girls and tell anyone with an ailing computer to turn it off and on again. Noel Fielding lives in the cupboard. Their female boss knows nothing of these annoying computer thingies and is preoccupied with her car crash love life.

In honour of this festive extravaganza, fans have voted for their favourite episode and Linehan has nominated his. There is also a repeat of the final one-off show from earlier this year and a documentary featuring interviews with cast and A-list fans.
