From Greek Mythology, by Gordon Lawrie

In Greek legend, the twins Noxos and Cretinos argued from earliest childhood. Later, they branched out into politics, invariably taking opposing positions simply for the sake of it.
 
Soon, they headed national campaigns: leading opposing parties, for or against independence, in abortion, gun control or gay marriage debates, their unpleasant faces came to be familiar household fixtures on live TV debates.
 
But this being Greek legend, the Gods had a suitable punishment in store. Noxos and Cretinos were condemned to sit together for ever, gazing silently at endless TV debates in the one place that never tired of them: Pluto.
