Portland, Ore. ? It might be the only time this season that fans are allowed to shred their own documents at the ball park.

The Portland Beavers, the Triple-A affiliate of the San Diego Padres, are sponsoring “Arthur Andersen Appreciation Night” to poke fun at the beleaguered accounting firm.

At the July 18 home game against Edmonton, anyone named “Arthur” or “Andersen” will receive free admission. And the first person named “Arthur Andersen” will get a gift package that includes a party inside a luxury suite for 80 friends.

Fans are encouraged to bring old documents to be destroyed at several “shredding stations” throughout the park. The team also will tuck away certificates for a game of “massive debt hide-and-go-seek.”

Arthur Andersen, based in Chicago, was convicted of obstruction of justice last month for shredding and altering documents related to an investigation into energy trading company Enron’s complex accounting practices.

When telecommunications giant WorldCom, which also is audited by Andersen, announced it had concealed $3.9 billion in losses, the Beavers decided to have some fun with the scandals.
