Tricky TV is a magic and illusion show aimed at children and teenagers, presented by magician Stephen Mulhern. Each episode combines close-up magic, practical jokes, and large stage illusions. A feature of the show is that, each week, viewers are shown how to perform a simple magic trick using common household items. Each show ends with a performance of a classic stage illusion, such as Sawing a Woman in Half. During the show's first season, Mulhern was joined each week by a different guest celebrity, who usually acted as his assistant in the final illusion in addition participating in other parts of the show. From the second season onwards, his Ministry of Mayhem (2004) co-presenter Holly Willoughby joined the show as Mulhern's regular assistant for the final illusions.
