The Super Bowl halftime show is arguably as big a spectacle as the actual game. And back in 2015, it launched an unwitting star.
Katy Perry was the halftime artist, but one of her dancers stole the spotlight. During her performance of the song "Teenage Dream," she was flanked onstage by two dancers dressed in enormous blue shark costumes. The one on the right seemed to dance in sync; the one on the other side flailed as if he'd been encased in that costume against his will.
"Left Shark" became an instant sensation.
