Sittin' around and havin' a laugh

Why should this lot be happy? Can't they see that things aren't going their way? Don't they know they're going to find themselves on the wrong side of history, forevermore to have their motivations questioned and their actions tossed about by revisionists? Or is it simply that they're happy because they're not at home ? You know how it goes..."I'm just stepping out to get some cigarettes...back soon dear". Or is it the company of men brings a certain relief? Is the fresh pine scented country air? Or is it that Germans are actually the (secret) happy people of Europe?
