In each destination Smith must complete five undesirable challenges. If he fails a challenge, he must perform something unpleasant called a "forfeit". The more he fails the worse the "forfeit". Watch him eat things that smell bad, lose wrestling matches, struggle to understand what people are talking about, and undertake all manner of odd challenges. No matter where in the world he is – be it Iceland, Morocco or the USA – Grub manages to look equally ill at ease in all of them. Grub is everyman: you will see yourself in these humbling and amusing experiences. Don't pack your bags – laugh as Smith does all the work for you.
