Best Ever Win Against: Dallas Cowboys

For me it was the 2006 game when Payton came up with a game plan that used Karney for 2 TD's. Completely had Parcells confused on how to stop the Saints.
This is the first one that came to mind. Because this was the moment we all realized the Saints were actually good.

But 2010 Thanksgiving game when Jenkins stole the ball. I was there in Dallas and it was just insanity.
