You may not have the $2K to bid on a paddling adventure with Christie Brinkley, but who could resist the temptation to go for a rare Caddyshack tee shirt autographed by both Bill Murray and Chevy Chase? (it could be yours for $150.00). These are just a few of the darned nifty celeb offerings available via the Third Annual Chevy Chase Earth Day Auction hosted by clever online fundraisers Charitybuzz. This year's auction will benefit a trio of good causes: The Center for Environmental Education Online, Earth Day Network, and The New York Coalition for Healthy School Lunches. If kayaking the waterways of East Hampton with Christie doesn't do it for you, there are plenty of other fun options: VIP Tickets and backstage passes to a Dave Matthews show; Brunch with Blythe Danner; Meet Martha Stewart; A Tennis match with Chris Evert; Daily Show Tix; An internship with TreeHugger; and many many more!
