"We are number one" is a song performed by Stefán Karl Stefánsson in the 2014 LazyTown episode "Robbie's Dream Team". The song represents Robbie Rotten's (Stefánsson) desire to unite three inept clones of himself in order to achieve greatness. I believe this song represents what the United States is all about - uniting to become ONE to achieve a goal, as the UNITED states of America. We Are Number One
