A Buffalo Bills fan thought it would be a good idea to slide down the wall of the upper tier of the Ralph Wilson Stadium. Of course it ended in disaster when he fell down into the crowd beneath him.
He suffered a shoulder injury but also caused a head injury to the person he landed on. Neither were life-threatening but the last thing you need when enjoying a game is for some eejit to come flying down on top of you.
Keep an eye out for the bright spark in the top left of the video.
