This happened down the road in Austin where a family set up their Christmas decorations to look like the scene from "National Lampoon's Christmas Vacation." They used a dummy of Clark Griswold hanging from the gutter. Then someone saw it a few days ago, thought it was a real person, and called 911.
Side note: Cops are not making them take down their decorations, they had to put up a sign letting people know NOT to call 911!
In case you never saw the movie reference, here it is below:
