Why did Paula Radcliffe apologise to the nation? What sports have been played on the moon? What did Muhammad Ali trademark?
And do Roisin Conaty, Judi Love, Joel Dommett, Dane Baptiste, Kerry Godliman and Tom Allen have any idea of the answers to those questions? Jimmy Carr hosts a big fat night of pointless sports trivia.
With Charles Dance, some inimitable performances from the kids of Mitchell Brook Primary School, and a whole host of celebrity question setters.
Big Fat Quiz Of Everything: Sports Special airs Sunday 14th May at 9pm on Channel 4.
