Get Your Own Back

Get Your Own Back is a British children's television game show created by Brian Marshall. Each episode staged a contest between teams of children – attempting to score as many points as possible – and their respective adults – attempting to make tasks as difficult as possible for their child contestants – playing a variety of games. The winning child earns a right to get revenge on the adult by ejecting them into a tank of gunge; adult contestants in the show are somewhat embarrassing, for a variety of reasons, to their child counterparts.
Airing on BBC One's children's television block, it ran from 26 September 1991 to 1 January 2004, and was hosted by Dave Benson Phillips. Lisa Brockwell also presented the final three series of the show alongside Phillips, and Peter Simon served the role of voice over in 1995.
Format.
The show consisted of two teams (the first series had three), each comprising one child contestant and a parent/relative/older sibling/teacher/celebrity (aged 16 to around 70) who in the child's eyes had committed some sort of crime that they wanted to seek revenge for. These 'crimes' were usually trivial, such as singing badly or asking the child to tidy their room. Dave and the audience always showed bias against the adults by booing them as much as possible.
Throughout every series the final round was called the "Gunk Dunk", where the losing adult was always thrown into a pool of colourful, messy gunge.
