There are a lot of black people in South Africa, but there are also an unusual number of white people (but Stephen Colbert doesn't notice, because he does not see color). The black people were already there, assuming that Africa is real, while the white people arrived on a flaming meteor sent from Australia. This explains the similarities between how Australians and South Africans speak. Also contributing to this is the fact that South Africa is upside-down, as is Australia, and while South Africans typically aren't as drunk as Australians, they do enjoy their liquor. In fact, the South African Breweries ran a recent beer commercial that attempted to portray South Africa as the center of the world (and remember, it might not even exist!) using Johnny Clegg's song "Osiyeza (The Crossing)" i
