Robyn on “SNL’ with Katy Perry and Bill Hader. (Dana Edelson/Associated Press)

Despite looking like he’s about to collapse from lack of shut eye, Killam gives a pretty impressive performance, even recreating the backward somersault from the Swedish pop singer’s video. Vanessa Bayer, Bobby Moynihan, Abby Eliott and writer Sarah Schneider provide some background lighting effects. Writer Zach Kanin attempts to keep working.

Below, for your viewing pleasure, is Killam’s re-creation, Robyn’s original video and her performance of the song on “SNL.”
