From the arctic conditions of Iceland, to rural India, Mexico, Germany, across America and to Tokyo, Karl's turning his attentions to life's other big issues.
Tonight, he'll ponder the point of art in America. He'll meet artists who make sculptures out of dog poo, try to make a masterpiece out of his own vomit, and strip down to his pants for some performance art in Times Square.
Other issues he'll be investigating this series include delving into the rules and values we should live by, fighting crime on the streets of San Diego with real-life superheroes, and experiencing the day in the life of a polygamist.
