That's because of the super creepy guy standing behind Smith during most of it. The man, who appeared to have a credential to be on the field, appears to be very interested in what Smith has to say and doesn't at all try to hide it. His eyes grow larger at times and it feels as though he's looking directly in the souls of the viewers at home.
He also manages to hang in the picture for the chat with wide receiver Michael Crabtree before the camera finally shifts the spotlight away and onto defensive end Justin Smith...much to the appreciaton of countless folks watching all across America. All in all, this could go down as the videobombs of all videobombs. I'll let you be the judge of that.
