This video is too adorable to pass up! Watch these twins dance along to the childhood nursery rhyme "If You're Happy and You Know It, Clap Your Hands."

It's been a rough week. And after it all, the sight of these adorable twin babies getting into it over who knows what warmed my heart. From the looks of their interactions and body language, it seems like their understand each other.

Watch the little girls communicate in a language all their own.
