Well, I will say that when I lived for a few years in Germany, a lot of them did smell really bad. Especially in close places, like elevators and subways. And the men's hair was very greasy, because they didn't bathe very often.
Whereas you could usually spot the Americans in the crowd, because they had that "fresh scrubbed" look the Germans lacked. But that was 30 years ago, and I'd have thought more had gotten into the habit of showering by now.
As for British romance, I once made a silly video, with a pair of Japanese martial arts experts fighting with wooden staves, like samurai, screaming and yelling all kinds of Japanese at each other. Had a real job finding a couple of guys who could do that authentically, BTW.
And I subtitled it, except the words matched an English drawing room scene, and went something like this:"Oh, Roger, I feel us growing apart. Do you feel it, too?"
"Yes, Clive, and I don't know what to say, or to do about it."
"Perhaps a weekend in the country would help."
"But we ARE in the country, don't you know, old man."
"Oh, righto, so we are, how silly of me. Then perhaps a weekend in town would do the trick."
"Afraid not, old fellow. Not until I break a bone or two, what?"
"Well, that's not very sporting of you, is it? Hardly the way to win my affection, wouldn't you say?"
"Well, there are different kinds of affection, old chap. There was a time I fancy you rather favored that sort of thing, what?"
"Yes, but a fortnight or two in hospital rather cured me of it. All those tubes and casts become a most frightful bore, don't you know."
And so it went, until I cut away to another bit of video nonsense. I really do adore the British, don't you know, dreadful love making and all.
