Squirrel Attacks Deer, Squirrel Wins, AFV Video. This crazy squirrel does not care who, or what you are. All it cares about is you getting out of its personal space. The Deer goes crazy after the squirrel pulls a Clark Griswald on him. Do you remember when the squirrel attacks Chevy Chase in the Christmas Vacation. It is almost Christmas time. Gratuitous Christmas Vacation video is below the squirrel video.
