On the road of life there are football fans and there are Steeler fans
I have observed over my years of football that Steeler fans are not particularly obnoxious in that Eagles fan - Raiders fan - Giants fan way, nor arrogant in that Cowboys fan - 49ers fan way. They are however like genital warts, it seems like one in five Americans is afflicted.
In related news I have also noted that Pittsburgh, like New Jersey, is a popular place to be 'from,' as in I'm from there but sure as shit don't live there anymore.
