Wisdom and Callum set their older brothers Kenny and Adam crazy tasks to find out who the best bro is. Winning can only be compared to the greatest of accolades, while losing leads to the undertaking of an awful, embarrassing forfeit. When Kenny and Adam are sent Wild West costumes and a list of challenges, they must do all they can to become top class cowboys. They need to prove who can swing the best lasso, fire a water pistol fastest, and drink the most juice in the bar slide challenge. Yeehaw! Then, once the dust has settled on the Old West, the bros go head to head again... exercising, in a contest to see who can produce the most sweat! The overall winner will be able to hold their head high, while the loser will find their head gets covered in desert... in the long desert forfeit.

Adam and Joe go head-to-head in a challenge to spend the day living as worms! Will they like their lettuce lunch, learn to slide around worm-style, and escape the scary seagull?
