Sometimes you click on a video and you know that it’s going to be massive. Gangnam Style, and What The Fox Says are good examples of that. So strange and unlike anything out there, that you know people are going to be sharing them all over the joint. If this video doesn’t join them (and it’s annoyingly catchy, so it should) then I don’t know what the world is coming to.
Personally I like to believe that the middle one is just a regular japanese schoolgirl who joined this idol group and is wondering why everyone is looking at her strangely.
