Frank Skinner is one of Britain's most controversial comedians but even he felt the comments broadcast last year by Jonathan Ross and Russell Brand on BBC Radio went too far. As he experiments with reducing the expletive count in his own stand-up show, Frank sets out to discover if the Ross-Brand storm really was a watershed in broadcasting's debate about bad language and offence. He quizzes leading comedians, media bosses and viewers to get to the bottom of a very British subject.
