As our quintet of cowering comics head out into the wilderness, Alex takes notes and records numbers with admirable (bordering on irritating) efficiency. It's the penultimate episode of the series, and Alex Horne's notes show that Dara O Briain holds a very slender lead in the race to claim television's most prestigious prize: Greg Davies's golden head on a plinth. John Kearns blunts the business end of a sausage, Fern Brady struggles with a raspberry, and Munya Chawawa unwittingly forces Sarah Millican into finding a novel use for a ping-pong ball.
