Comedian David Baddiel reveals his father's struggle with Pick's disease in this documentary, which is a rare form of dementia that makes him prone to extreme outbursts of swearing, aggression and sexual inappropriateness. Filmed over the course of a year, it charts David and his brother Ivor's attempts to care for their dad in the aftermath of their mum's death. Speaking to Radio Times, Baddiel said: "The comedy of the documentary is that he was always unbelievably rude, sweary, antisocial, impatient, moody and sexually disinhibited, so it was very difficult to understand it as a disease."
