Shake It Off Aerobics video

SWIFT MOVES: As long as we're on the subject (and when aren't we of late?)... Lest you believe 1989 is a mere homage of a title, this YouTube mash-up miracle—in which Taylor Swift's mega-smash "Shake It Off" (Big Machine) is synced to the 1989 National Aerobics Championship, brought to you by Crystal Light—will help you understand how accurately Swift captures the zeitgeist of that bygone era. And if you don't have a sick grin on your face while watching it, well, we just feel sorry for you. And now, a word from our sponsor. (11/7p)
