Chevy Chase and his wife, Jayni, are auctioning off items donated by their famous friends to raise funds for the Center for Environmental Education's Web site.

The online auction at www.charityfolks.com starts today and continues through May 6. Backstage passes and tickets to a David Bowie concert, a two-week internship at Rolling Stone magazine and lunch with former President Clinton and Chase, a former SNL star, are among the top items up for bid. They hope to raise at least $250,000.

"One of the fortuitous things about this is that I'm a movie star," Chase said. "And I have a lot of friends who are rock stars and movie stars, so I wrote to them personally and told them about the auction and asked for their help."

Chase and his wife founded the nonprofit education center in 1989 in California. The center has since moved to the Environmental Studies Department at Antioch New England Graduate School in Keene, N.H.

They plan to upgrade the center's Web site with the funds so that resources are more available to elementary school teachers, and students can share their environmental work and ideas online.
