There are no words to describe this incident if it happened as described.
The primary reason I put the little disclaimer "if it happened as described" is that I have been to games in opposing team stadiums, and I'm not seeing how these guys if they did what is reported lasted into the fourth quarter.
Think of Heinz Field on a Sunday. Try to imagine a handicapped kid with his grandmother waving their terrible towels and watching the game. Imagine 15-20 Ravens fans calling him Timmy and making fun of him.
Now imagine what Pittsburghers would do to those guys.
But considering that this week I saw a report that a mother and daughter wrote a fake letter about a husband and father dying in Iraq, so that they could win Hannah Montana tickets, nothing surprises me.
Either way, true or not, we live in a fucked up world.
