On February 3, the San Francisco 49ers and the Baltimore Ravens will take the field in Super Bowl XLVII. A football game will be played. Passes will be caught, assignments will be blown, groins will be pulled. And one team will win.

But that doesn't mean everything can be predicted. Certainly the game's organizers couldn't predict it in 2004 when, during the halftime show, Justin Timberlake ripped off part of Janet Jackson's outfit and a boob came tumbling out.

That wasn't the first time forbidden celebrity skin had ended up in primetime. If anything, the pace is picking up. We're seeing more pop-outs and slip-ups than ever. 

BeyoncĂ© is booked as the headliner of the halftime show for Super Bowl XLVIII. Could history repeat itself? We'll see, but first, take a moment to get to know that history with this look at great moments in accidental nudity on live TV.
