Rob Beckett

Guest host Claudia Winkleman welcomes Hollywood star Chris Pratt, actor Toby Jones, Northern Irish actor Saoirse-Monica Jackson and comedian Rob Beckett; musical guest Rachel Chinouriri performs.

Celebrities Al Murray, Sara Pascoe, Paul Chodhry, Dave Gorman and Rob Beckett face a set of bewilderingly brilliant tasks involving snowmen, vegetable propulsion and Swedes.

Alex Horne spends an hour cooped up inside a shed and someone must take his place when he emerges. Rob Beckett uses cement to fill a shoebox, and Dave Gorman appears a little bitey.

Al Murray takes extreme measures to maximise his points after being confronted with an eggcup, while Sara Pascoe performs extraordinary feats with a few balloons and a loaf of bread.

To impress taskmaster Greg Davies, the five comedians are challenged to give an item of clothing to a passing cyclist and interview an 83-year-old man.

Jimmy Carr hosts, as Sean Lock and Rob Beckett take on Jon Richardson and Claudia Winkleman, along with special guests Nick Mohammed and Joe Wilkinson.
