Kindergartners sing 'Day Man' from 'It's Always Sunny in Philadelphia' - Watch

From the bizarre and fun file comes a video of Japanese kindergartners singing "Day Man," a song written by Dennis ( Glenn Howerton) and Charlie ( Charlie Day) on "It's Always Sunny in Philadelphia."

It sounds better coming from the children than it ever did from Dennis or Charlie, but one has to wonder where this video came from. Who had the idea of teaching these kids the song? Most importantly, why is Peter Griffin from "Family Guy" drawn on the dry erase board behind them?

In the end, none of those questions will be answered and they don't really need to be, because the above video simply existing is enough. Enjoy their version of "Day Man."
