There are several confusing elements that take place in this video:
1. Of all the songs available in the world, why did some adorably cute Japanese kids end up singing DayMan from It’s Always Sunny in Philadelphia?
2. Why is there a drawing of Peter Griffin hovering over those children on a whiteboard?
I don’t know if we will ever find the answers to those questions but at least there is video evidence that the world is in love with Charlie, Dee, Dennis, Mac and Frank.
Video after the break.
