Chances are you've seen the viral video hit "What Does the Fox Say?"
Well, now a Halloween display at a Leesburg, Va., home is asking that very question.
The incredible light display -- powered by more than 8,500 lights -- is synced with the popular song by Norwegian comedy duo Ylvis.
The show runs on a continuous loop from 7 p.m. until 9 p.m.through Halloween.
As for that electricity bill, the family says it costs about $25 to $35 to run the display during the Halloween season.
