Rob Beckett and Romesh Ranganathan take on more challenges, beginning by heading off to Los Angeles to throw themselves into the world of Hollywood stuntmen. They meet The Fall Guy stars Ryan Gosling and Emily Blunt before training with the film's director David Leitch, then head back to the UK to perform a stunt on Hollyoaks.

Scottish band Bleed from Within try to educate Rob Beckett and Romesh Ranganathan in the ways of the headbanger in time for a surprise performance of Metallica's Enter Sandman at the Download festival in front of 4,000 fans. The boys also get some extra tips from US rock stars Wheatus and Queens of the Stone Age.

The UFC offers the boys exclusive behind-the-scenes access with some of MMA's biggest icons... if they compete in the Octagon in front of a live crowd.

The duo go behind the lens and test out their photography skills as part of the Natural History Museum's Wildlife Photographer of the Year.
