Noticing headlines in a newspaper stating that Rolf Harris had been seen in the Outback, the Goodies go there in search of their quarry (to the strains of "Waltzing Matilda").
The Goodies are upset at losing their latest star attractions, and are also very worried — Rolf Harrises used to be all over Australia, and they were prolific breeders.
Another year has passed, and England is overrun by millions of Rolf Harrises who proceed to make life uncomfortable for other people by their actions — including frightening small babies in their prams, taking over television broadcasts and completely dominating some sports teams.
The Rolf Harrises also constantly splash paint everywhere (even onto people) and sing "Tie Me Kangaroo Down, Sport", accompanied by wobbleboards.
An anonymous Queen makes a proclamation — whosoever could rid England of the Rolf Harrises could marry her eldest son (Prince Charles), or receive a thousand OBEs.
