Karl aims to get to the bottom of his relative lack of a vocation, and visits an 85-year-old Japanese inventor to discover whether he has what it takes to become a genius. When the results prove less than encouraging, he sets his targets a little lower by trying his hand at becoming a traditional Japanese handyman. On the opposite end of the spectrum, he hangs out with a self-made millionaire in South Africa and jets off to Los Angeles to strut his stuff in a Hollywood fashion show. Karl makes a favourable impression on brazenly ostentatious South African playboy Kenny. Kenny's the kind of guy who sits on a throne at home and is keen to show off his wealth to the cameras, so Karl receives the full rap-star treatment. He sips champagne by the pool, rides in a helicopter and gets a facial. And then moans about it all.
