Argentina ... From the cosmpolitan streets of Buenos Aries to the dramatic landscapes of Patagonia, this country is writhe with breathtaking extremes. In the first episode of the series, the Wildboyz along with Johnny Knoxville find out if they have what it takes to be gauchos (Argentinian cowboys), view an orca feeding frenzy, and try to keep goals against the Boca Juniors soccer team. Other activities include the boys having a duel with cow-prods, eating bulls testicles and Steve-O taking a pack of dogs for a 'walk'.
