Something about Northeastern fans... Boston, NY, Philly... I dunno. Although, I never got that from Buffalo fans, so maybe just literally big city East Coast fans...,but the obnoxiousness is noxious...
From the city of Brotherly Love... Philly fans are the only fans to ever knock out Santa with an Ice ball... Santa riding around the outer ring during an Eagles game and a fan...BOOM...KO Santa. Who chunks a hunk of ice at Santa? Philly fan. It wasn't the only piece of ice or snow thrown, it's just the one that hit.
Philly fan has also on occasion throw batteries, etc. Not to mention the conduct at the game. Old Veteran's stadium? hooo man. I knew plenty of grown men who wouldn't go to see an Eagles game...AS FANS!!! (I have plenty of family in the Lehigh Valley and on the Jersey side as well). Philly used to be my second team for a lot of years because of the family connection.
And once I got on the internet? holy moses... That guy, EDP, who loses his mind about all things Eagles...isn't far off from the average Philly fan from Philly.
I feel bad for Cleveland fans, but those folks are devoted and they just want to see a decent product on the field. They actually show up in that gawd awful weather and they've been served crap sandwiches for so many years now. It wouldn't surprise me if Hue Jackson turned them around, actually. Better them, than the Eagles or the *gag* 9ers...
