John Mayer "Paper Doll" (Prancercise version)
While Jazzercise tries to maintain its coolness (Ed. really?), the lovely Joanna Rohrback keeps things real with a lovely Prancercise routine (Ed. technically, she's romancercising) set to John Mayer's new tune.
And yes. Prancercise is a real thing. Giddy up.
