A "stereotypical Eagles fan" is basically your typical a-hole fan. I know every sports fanbase has those types of fans somewhere, but the Eagles fanbase is one of them that actually has a reputation for fan misconduct. The incident that gets the most publicity is the one where fans in Philadelphia booed Santa Claus off the field at Halftime during a 1968 game. There was also Bounty Bowl II (a game where fans threw battery-filled snowballs at opposing players and coaches during a game against the Dallas Cowboys in 1989, but some of those snowballs even ended up hitting the CBS broadcast booth, as well as Philly's own players), a riot on a nationally televised MNF game that led to a prison being installed in the stadium, and an incident where Eagles fans celebrated when Michael Irvin got injured (as it turns out, that injury ended Irvin's career).
