 The constant references to gibbons date back to the 1960s radio  series "Im Sorry, Ill Read That Again" which starred the Goodies  alongside John Cleese, David Hatch and Jo Kendall. This explains the  huge laugh in the "Radio Goodies" episode where Graeme calls their  pirate ship "The Saucy Gibbon". The 1975 season contains graffiti  references to "Funky Gibbon", scrawled on the wall near Graemes  computer. This was a novelty single recorded by the team that  reached number four on the British charts.
