In this season finale, the Wildboyz return to Mother Russia.

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'.

Tonight the boys travel to Moscow where they are joined by ex-Jackass costars Johnny Knoxville and Loomis. Amongst other things tonight they achieve zero-gravity in a jet over Russia.

Thailand ... A kingdom renowned for ornate temples and exotic wonders, this country has maintained centuries of tradition with a culture all its own. Tonight the boys check out some crocodile wrestlers, race buffalos, get Angelina Jolie tatts and try some local cuisine. Steve-O meets a scissor, knife and spoon thrower and Chris gets a massage from an elephant.

After traveling the world, the Wildboyz wind up in their own backyard: California, home to ferocious animals and celebrities.

The Wildboyz go south of the border to mingle with America's next door neighbor.

Don't cry for them, Argentina! The Wildboyz return to further butcher the traditions of this exotic country's native people.

Steve-O and Pontius return to Thailand to take on tigers, tranvestites and titanic toilets!
