Australian comedy has a strong tradition of self-mockery, from the outlandish Barry McKenzie "expat-in-Europe" ocker comedies of the 1970s, to the quirky outback characters of the ""Crocodile" Dundee" films of the 1980s, the suburban parody of Working Dog Productions' 1997 film "The Castle" and the dysfunctional suburban mother–daughter sitcom "Kath & Kim". In the 1970s, satirical talk-show host Norman Gunston (played by Garry McDonald), with his malapropisms, sweep-over hair and poorly shaven face, rose to great popularity by pioneering the satirical "ambush" interview technique and giving unique interpretations of pop songs. Roy and HG provide an affectionate but irreverent parody of Australia's obsession with sport.
