it's a mystery. i find it very similar to Austin Powers whole issue with mojo. when Favre has it, he is simply amazing and has a great sense of humor. however, there is a conspiracy that Dr. Evil managed to infiltrate Favre's home at night, keep him asleep, and managed to steal his mojo. This happened shortly before the season of 2005 began, you know, when he threw 29 interceptions. he wasn't having much fun that year with a horrible OL and no wr's. thanks to the English and Austin Powers, they used their extra groovy time machine to go back in time, stop Dr. Evil's hedious plan, and returned Favre's mojo back to Favre, thus helping create this shaggadelic 2007 season.
