Rusty Hampton, of the Jackson Clarion-Ledger says this picture of Brett Favre—offensive coordinatin' for the Oak Grove Something Or Others—shows the Ol' Gunslinger voicing some displeasure with the referee in the foreground.
But really, there could be any number of reasons why offensive coordinator Brett Favre is upset. Maybe his playbook ("Go deep.") is too complicated for his high school charges and they keep screwing up. Maybe his head coach is named Rodgers McCarthy. Maybe he was driving to the game that night and some asshole cut him off so he had to jam on the brakes and his wife said "I really hate that you have a small penis."
It could be anything.
