A one-off return for the light-hearted show in which comedians and other famous faces reveal how they struggle against that unique combination of being a Brit facing up to all that 21st-century life throws at them - only this time they're complaining about the festive season and all it brings. Julia Walters narrates, while the likes of David Tennant, James Corden, Romesh Ranganathan, Catherine Tate and Danny Dyer ponder how much to give carol singers, how to leave a party early and bad singing during midnight mass - with US comic Rich Hall giving an outsider's view of how daft Brits can be.
