As the lads' epic adventure enters its final leg, Freddie, Jack and Jamie drive into Sin City for three last make-or-break challenges. With the thought of having to perform live on stage with the Chippendales hanging over them and with Jack and Jamie nursing hangovers from a big night on the town, their first stop is James's favourite restaurant, Heart Attack Grill, where victory will come to the first man to polish off a calorie-laden Quadruple Bypass Burger and Flatliner Fries.

Then with stomachs full and heads still pounding, it's off to the race track for a high-speed NASCAR challenge. Finally, Fred, Jack and Jamie are joined by James for their last chance to pick up some points when they are made to perform in Cirque du Soleil spectacle Zarkana.

Following their (less than agile) acrobatics, the points are totted up and it's revealed who will be stripping live on stage with the world-famous Chippendales. However, even then, James has one last Las Vegas surprise in store.
