In its third year, Laugh or the Polar Bear Gets It will not only provide you with a whale of a time, but will go a long way in supporting Friends of the Earth's mission to promote a positive relationship between people and the environment.

Some superb new acts have joined the stellar line-up at this year's event at Hammersmith Apollo including Josh Widdicombe - star of 'The Last Leg' (C4) and 'Live at the Apollo' , Edinburgh Comedy Award nominee Tony Law and Danny Bhoy, as featured on The Late Show with David Letterman and 'Live at the Apollo'.

Already onboard to create another show-stopping event are Stewart Lee, Ed Byrne, Dan Antopolski and Francesca Martinez, with more exciting names to be released.

NB: Unfortunately Beardyman is unable to perform.

Tim Minchin said of last year's show: "This show's titular threat is deadly serious. If you don't come and laugh, we have an actual metaphorical polar bear and it is seriously going to get 'it'. Luckily, we are not worried, because (a) the line-up is excellent, and (b) we don't know what it's a metaphor for!"
