Let’s ask Jason Gay of the Wall Street Journal. I love his response.
“Cowboy partisans were miffed that Mr. Favre threw a fourth-down touchdown pass to give the Vikings a 34-3 lead with little time left. They considered it unnecessary and obnoxious, and they're right. Anyone who's taken a gander at the new, billion-dollar Cowboys Stadium, with its $40 million scoreboard, knows that if there's one thing that the Cowboys don't like, it's something unnecessary and obnoxious.”
