Corbett is suggesting that if you can’t go up those long MRT steps, perhaps you should Grab Your Ass . . . I’m thinking, that looks awfully weird . . . the video is quirky and strange particularly for its seriousness . . . I suspect the system would work much better though if instead of grabbing your own ass, folks were encouraged to grab their neighbor’s ass . . . that makes for a much more entertaining system . . . but don’t come crying to me when you get picked up by the police for grabbing the wrong person’s ass.
