There is a new commercial for The Finish Line sporting goods store that has track runners racing around an auto track(think Daytona). The quirk to this is that there appear to be two busty women in the clip. The first is probably a large C or D(yellow "Meb" shirt), the other is in some sourt of zip up skin-tight suit(also yellow) and she is just jiggling and wobbling all over the place.
Keep your eyes open, you might just see(or cap) it.
