Mom's Annual Back-To-School Dance Video Is Particularly 'Happy' This Year

Massachusetts Mom Tracy Moutafis has made a name for herself with her annual back-to-school "happy dance" videos. And this year, she couldn't have picked a more perfect song to celebrate her sons' first day of school: "Happy" by Pharrell.

Clap along if you feel like a mom with more alone time!
