I met a strange man who claimed to be a time traveller from the future, researching the collapse of human civilisation.
He asked me where it all went wrong.
I said, the Americans thought they could sell Sesame Street to the Russians.
He said, I know what Sesame Street is, but what are Americans and Russians?
I explained as well as I could, and he nodded sadly, and went on his way, apparently satisfied with the explanation.
