This funky rocker was written by Pink together with Tony Kanal of No Doubt and his writing partner Jimmy Harry. Pink said on her website that she "fell in love working with them."
Pink explained on her website that this song is, "about when the box you're in doesn't fit anymore, burn that f---er down and start a new one."
Pink explained the album's title on her website: "I look at life like a carnival. Clowns are supposed to be happy, but they are really scary. Carnivals are supposed to be fun, but really they are kind of creepy. But, we go and we buy cotton candy and we force our laughter and we get on rides and we strap ourselves in and we do it. And that's like life to me, and love. Love is supposed to be fun, but it can sometimes be really scary. And the funhouse mirrors that make you look so distorted that you don't recognize yourself and you ask yourself, 'How did I get here? How do I get out of here?' But, you think that you want to do it again. That is the same as love and life. It's a metaphor for being in love and for life."
