Celebrate the kid inside with Oreo's 100th birthday. When did everything get so serious? Since 1912, we've made it our business to make life a little less serious. In a world that's become far too adult, a couple of Nabisco Oreo Chocolate Sandwich Cookies, a glass of milk, and a shared twist, lick and dunk is all it takes to get back to that carefree feeling of childhood. For our 100th Birthday we're here to remind you that there's a kid inside all of us who deserves to be set free every now and then.
