ROSEMONT, Ill. (AP) -- Steve Bartman has refused yet another offer to cash in on the moment he became the most famous -- or infamous -- Chicago Cubs fan in history.

Bartman friend Frank Murtha says that Bartman won't accept an offer of $25,000. For the money, all Bartman would have to do is attend the National Sports Collectors Convention in Rosemont and autograph a photograph taken of when he tipped a foul ball that seemed destined for Cubs' outfielder Moises Alou's glove during a 2003 playoff game with the Florida Marlins.

Bartman was vilified by Cubs fans, who thought that he helped prevent the team from reaching the World Series. Alou has since said he wouldn't have caught the ball.

Bartman has declined all offers to appear or make money off his brush with fame.
