The goal is to get men to take a pledge to stop shaving in the days leading up to World Environment Day, which is on June 5. The average man will waste 3-10 gallons of water each time they shave, and, through this campaign, Anheuser-Busch aims to save 1 million gallons of water.
Anyone interested in making the pledge can visit the "Grow One. Save a Million" Facebook page and get more information about how to help. Offerman and the rest of the "Parks and Recreation" cast will be back for Season 4 this fall.
