Here's Janet singing the decade-old Rhythm Nation, complete with canned crowd noise. If you've ever been to any live halftime show, you KNOW the crowd is doing everything except relentlessly cheering the hooha on the field. You're looking for the beer guy, the bathroom, any hot chick in your section, your keys, your kids, your wife, your wallet - but you're NOT cheering. And neither is anyone else.
I will say that even though CBS has its head up its ass as far as what commercials it deems acceptable, their HDTV really genuinely rocks.
