Roy and HG are an Australian comedy duo, comprising Greig Pickhaver in the role of "H. G. Nelson" and John Doyle as "'Rampaging' Roy Slaven". Their act is an affectionate but irreverent parody of Australia's obsession with sport. Their characters are based on stereotypes in sports journalism: Nelson the excitable announcer, and Slaven the retired sportsman turned expert commentator. In his 1996 book Petrol, Bait, Ammo & Ice, Pickhaver summarised the duo's comedic style as "making the serious trivial and the trivial serious".
