Russian Around

There needs to be a family sitcom called "Russian Around"; it would be set in the cold war, where a bumbling Russian spy rents a spare room from a stereotypical American family, and we laugh as he fails to grasp concepts like "freedom" and "thanksgiving", and he also fails to actually spy on anyone; but despite the strong Russian accent and behaviour, people all think he's just a quirky friend, not suspicious at all (mostly because that would cause a sudden violent and depressing end to the series...)

My first analysis of that brainwave is "Amusing mental image, probably wouldn't be very successful in practice"; but then I look at other sitcoms and think "oh wait, everything else is worse". So, anyone want to invest? :P
