If you go to an NFL game this year, you better watch your temper or you'll be banned from any NFL game by the league until you take anger management courses.
I came across this one over at BTSC and then watched the video over at ABC News.
You will have to pay for your course, between $50-$100 and when you pass the league will be notified and then you can return to games. They didn't mention anything about repeat offenders but I would guess that you'll be on a short leash in that respect.
Word to the wise, let the mornic Ravens, Browns, and Bengals fans start the fight and then call for security and laugh as they get thrown out.
