So in the first game of the post-Favre era against their arch-rivals from Chicago, the Green Bay Packers are administering an old-fashioned butt whipping to the Bears.

As of this posting, the Packers lead by 31 points, 34-3.

If that score holds, it’ll be the  largest margin of victory in the series since 1996, when the Packers blasted the Bears at Soldier Field, 37-6.

UPDATE:  With a final score of 37-3, the difference of 34 points is the most since the Packers beat Chicago at Lambeau in 1994 by 37 points, 40-3.
