Celebrity Big Brother is a British reality television game show in which a number of celebrity contestants live in an isolated house trying to avoid being evicted by the public with the aim of winning a large cash prize being donated to the winner's nominated charity at the end of the run.

For charity, comedian Ricky Gervais and celebrity and husband of Anthea Turner, Grant Bovey train as boxers for a month before taking each other on in a boxing match of 6 rounds. The winner gets £5,000 to go to a charity of their choice.
