Is Your 'Stache Worth the Cash? Dairy plays such an important role in fueling active minds and bodies. Now dairy can also help you earn a college scholarship. Simply take a picture of your best milk mustache for the chance to win. Make sure a dairy product (milk cheese yogurt) is visible along with your mustache. The contest is open to students who are 17 years of age or older and are (or will be) enrolled in a post-secondary (university college or community college) in the state of Arizona for the fall term with at least 12 credit hours.
