Football?

The past two nights (ever since the UT game on Saturday), Abby has been asking to watch football.  It comes out of nowhere.

Here was our conversation tonight as we were playing in the living room.

Me: Abby, look on TV it's dancers (Miss Universe Pageant is on)
Abby:  Football
Me: See the pretty costumes
Abby: No, football
Me: But look at the dancers!
Abby: NO, NO, NO, NO FOOTBALL
Me: *changes channel to Monday Night Football*
Abby: *huge smile and a giggle*

Where did this come from???
