> > I think the ad is for JC Penny's...kids going back to school. I know it has kids of different ages dancing to the song on different commercials (one for grade school, one for high school). Some of it goes "Rock your body, (something?>"step") one, two". One of the kid dancers was in Missy Elliott's video. She is good. A little brown haired girl. Anyone know what it is? Thanks.
