If you stare at something long enough

I was trying to get the camera situated on the tripod and totally unprepared to make a picture when I realized that Bentley had been intently staring at the television for quite a while.  Baylee briefly joined him, then left.  I was not really surprised when several minutes later Shadow walked out from behind the television.  Then they had an eyeball to eyeball stare off. 

So, how did it end?  The spell was broken when I knocked over the tripod and they both scrambled for cover. No winner, no loser.
