NBC’s Thursday night block of comedy is home to one of the most magnificent mustaches ever seen on television. That mustache, of course, belongs to the character of Ron Swanson, head of the Parks Department in Pawnee, Indiana, on the sitcom Parks and Recreation. Swanson, played in real life by actor Nick Offerman, is a burly stereotype of masculinity and creator of the Swanson Pyramid of Greatness. When describing the perfect office atmosphere he states, “The less I know about other people’s affairs, the happier I am. I’m not interested in caring about people. I once worked with a guy for three years and never learned his name. Best friend I ever had. We still never talk sometimes.”

But epic mustachery aside, actor Nick Offerman has pledged to utilize his most prominent feature for the good of mankind: to encourage water preservation. Offerman is teaming up with Budweiser, the famed beer company, for its “Grow One. Save a Million” campaign, which began on May 17. On average men use between 3-10 gallons of water every time they shave. So, in preparation for World Environment Day (this Sunday, June 5), Offerman is encouraging all men to drop the razor and save water. Budweiser’s goal is to conserve at least a total of 1 million gallons (or roughly 5 gallons per person) of water by June 5 through this program.

In a press release Offerman stated: “The only thing manlier than growing a big, burly beard is ripping a big, burly beard off of a charging grizzly with your bare hands. That, and saving the planet. Since no grizzly has had the balls to charge me since I went through puberty, I’ve decided to focus on saving the planet by joining with Budweiser to promote the ‘Grow One. Save a Million’ campaign.

Men, if you want to look manly and feel good about conserving water, join me and take the pledge on Budweiser’s Facebook page. And grizzlies, charge me. Just do it. I’m waiting, you babies.”

Every strand of hair left on your face is one drop of water not wasted. So, this weekend start growing the beard you knew you were always capable of…for a good cause. And while you’re at it read about several water conservation breweries.
