David Ortiz and Dustin Pedroia are participating in the fifth Lindt Gold Bunny Celebrity Auction—which takes place between now and April 14th. All of the proceeds from the event go to Autism Speaks. This year, Lindt will also be matching contributions—up to $20,000. The auction brings together almost 100 athletes, actors, chefs and other top celebrities who lend their signatures to a porcelain Lindt Gold Bunny. You can participate in the auction by clicking HERE.
