Japanese Kindergarten Class Sings "DayMan" VIDEO

This is epic-cute! Yeah, I just said that! I'm a huge fan of It's Always Sunny in Philadelphia and The DayMan episode is one of my favorites. Even if you're not a fan of the show, I think you can appreciate the cuteness of of these kindergarteners in this video.

If you don't think this is cute, you have no heart.

Here's the Always Sunny crew, not as cute, but hilarious!
