The U.S. Open wraps up today, with Rafael Nadal and Novak Djokovic facing off in the men’s singles final. While we here at Audubon are divided on which player we’re rooting for (and some are still hung up on Roger Federer’s semifinal defeat), we can all get behind the U.S. Open tennis ball recycling program (though maybe not the rather lame commercial above with Alec Baldwin and tennis-ball puppets...he's so funny on 30 Rock, what went wrong?).

Of course, a few balls—the ones hit by tennis stars into the stands—are more likely to end up on lucky fans’ shelves than in Rover’s mouth.
