There was a pastie
That's partly why I don't see it as a big deal.
Drudge had a close up of the infamous boob and it was wearing a fairly large metalic star pastie.
The whole thing is ridiculous. The SB halftime is not and has not been family fare for years. They had just finished a suggestive song and a sugestive dance. If there was any offense it was well before the flash.
