It appears that Jerry Jones did indeed think of everything.
I don't know that that little structure qualifies as an actual cage, but Al Michaels referred to the ladies inside as "cage dancers." I guess that's what Jerry wants them to be called, so who am I to argue?
When a man spends a billion dollars on a stadium, that man is entitled to cage dancers. The game's actually not over as I write this, so I don't know what's coming next. Does the end zone roll back to give way to an oil-wrestling pit? Are there private viewing booths in the luxury boxes? I don't even want to think of the decadence and depravity that takes place in Jerry's owner's box.
Here's the national television debut for the cage dancers. If you happened to be at the game, and found yourself peeking at the cage dancers from an unseemly angle, and you feel a little bit bad about it, don't worry: Cris Collinsworth approves of your perversion.
