It's a bird! It's a plane! It's not Perry doing a Superman impression – the singer is simply "planking," an Internet trend in which people share photos of themselves lying flat in unlikely places. Perry first planked on a yacht on the Fourth of July, and then again on the mermaid-themed set of her new video. "PROPER planking FTW! #itswhatArielwoulddo," she Tweeted.
