Ah, the show that makes us all feel better about ourselves. The first mistake people who appear on this show make is trusting someone who goes by the name Dr. Pixie McKenna. This week it's off to the mobile clinic in Cardiff, where they offer advice on flatulence and, with half of the Welsh population failing to visit the dentist regularly, they are also joined by Dr James Russell and his pop-up dental clinic. Plus, Dr Christian Jessen advises a man with a bent penis. Watch if you dare.
