Kung Fu Kapers AKA Ecky-Thump - S5-E7
Trivia: In the previous episode on the wall of the Goodies' office was some graffiti reading "it's gibbon time". In this episode the graffiti now says "it is still gibbon time". This was to promote their single "Funky Gibbon" which was released when this episode was first broadcast, the Goodies released five novelty songs in 1974 and '75 - Funky Gibbon was the most successful, reaching number 4 in the charts, the opening line of Funky Gibbon is "Come on everybody, it's gibbon time".
