I know right! Frankly, I find this kind of parody much more pleasant than Gangam style (which is starting to be incredibly annoying these days...) Oh well, I'm a hopeless pacifist so songs like these make me smile straightaway.
And about the bagel people: it's so funny how the stereotypes about Japan are about a society that pushes people to be ordinary however at the same time everybody's like wtf japan... I mean, look at the awesome street fashion!! A country of contradictions after all.
