It had to be a graphic or something but it was a perfect representation of someone flipping the bird right down to the curved thumb and longer index finger. Ain't no way that was a natural cactus, it was too perfect. I ever rewound the DVR to let the wife see it and she agreed, just to good. I am sure some smart guy in the graphics department thought it would be funny. They went to the shot a second time just before the announcers came on for the pre race show.
I know what they do to drivers for displaying the proctologist's friend, I suspect Fox will have to issue an apology or something. I thought it was pretty funny.
