John Mayer is a bit of a tool, but his new music video is fantastic. He got the Prancercise lady to be the star. Joanna Rohrback, 61, created the exercise which she describes as A springy, rhythmic way of moving forward,similar to a horse’s gait and ideally induced by elation. It looks ridiculous, but must work. Who else do you know who can wear a belt with Spandex? I know people in passing cars must be asking themselves, “What the hell is that lady doing?” This video will go viral, but does anyone hear the song?
