After another flat first half by Brett Favre and the Minnesota Vikings, Randy Moss riled them up and Percy Harvin heeded the message. The Dallas Cowboys went home again unhappily, wondering what is happening to what was supposed to be a special season. Harvin's 95-yard kickoff return for a touchdown was just the spark the Vikings needed to overcome another uneven offensive game in a 24-21 victory over the Cowboys on Sunday. "We were desperate. You heard the panic word all week," said E.J. Henderson, who intercepted Tony Romo twice to set up 10 points for the Vikings. http://scores.espn.go.com/nfl/recap?gameId=301017016
