Sure thing but admitting defeat is not alway funny and you know the japanese they are very proud. So it would be a blame on that proud to admit you lost.
whe've got a saying here in Belgium: "Rare jongens,die romeinen." (Actually obelix says that in Asterix and Obelix
and that's a comicbook serie / cartoon/ movie.)
It means strange people, those romains. but it acually means strange people those other cultures. Don't try to understand them just leave it like that.
