From Zap2It.com: Kindergartners sing 'Day Man' from 'It's Always Sunny in Philadelphia'

Not for nothing, but 'Day Man' is one of my favorite songs. I used to watch that episode of It's Always Sunny in Philadelphia over and over again just to hear Dennis and Charlie's masterpiece. The only thing that makes this song better is having kids sing it. If you've never seen that ep of the show or even the show, god forbid, and you think these kids are totally adorbs, I highly recommend you check it out. The song is featured in season 3, episode 9: Sweet Dee's Dating a Retarded Person. Meanwhile, I'm going to start teaching my daughter to sing this song right now, even though she can't even speak yet.
