Maybe you know that Bruce Harper wore number 42 for the New York Jets from 1977 to 1984 and that he is the all-time leader in punt return yardage in Jets history. It's more likely, however, that you know that Fireman Ed wore number 42. He didn't back Joe Namath or Wesley Walker or Curtis Martin. The Jets' most famous fan wore a fireman's hat and a punt returner's jersey, until this year, when he threw his support behind embattled starting quarterback Mark Sanchez. Who knows what he'll wear next year? Fireman Ed retired last week as the team's superfan, vowing to lead a normal life and no more chants.
