Barry Humphries and a team of senior investigative reporters tackle the generation gap as they try to fathom youth culture. From super foods to swearing, political correctness and social media, Barry and his team are breaking down the barriers of age so any OAP can keep up with the grandchildren. Tonight, 94-year-old Bobby gets his grey matter around political correctness, octogenarian Laura gets to the bottom of reality TV fame as she chats to Geordie Shore star Charlotte Crosby and best friends Trish, Margot and Daphne go to Amsterdam to try marijuana for the first time. They say youth is wasted on the young, but will our seniors really want to swap gardening for Grindr?
