The Big Fat Quiz of Everything returns and it's bigger, fatter, and quizzier than ever - letting loose on not just the year-gone-by but well... everything. In this brand new episode, quizmaster Jimmy Carr asks questions from the last 100,000 years of human history giving a unique Big Fat Quiz spin on History, Music, Film, TV, Science, Crime and Scandal from every epoch. Jonathan Ross, David Walliams, Katherine Ryan, Aisling Bea, Noel Fielding and Richard Ayoade join Jimmy to compete for the Big Fat Quiz crown. Jonnie Peacock drops by to test the panel's sporting memories, and The London Philharmonic Choir are on hand to add a touch of class. Jimmy is ably assisted by Big Fat favourites Jon Snow, Mitchell Brook Primary School and Joey Essex as well as a whole host of celebrity question setters. So what diet did William the Conqueror attempt? What is Bill Gates' hidden talent? And why do tennis players wear white?
