It's A Knockout

It's a Knockout! is a British game show first broadcast in 1966. It was adapted from the French show Intervilles, and was part of the international Jeux sans frontières franchise. It featured teams representing a town or city competing tasks in absurd games, generally dressed in large foam rubber suits. Games were played in the home town's park, with weather often turning grassland into mud. The team scoring most points would advance to the next stage. Teams could double points in one round by choosing to "play their Joker". The games were originally refereed by Rugby League's Eddie Waring but eventually refereed by former international football referee Arthur Ellis from 1969 to 1982.
