No one's entirely sure where the Southern treat called the Goo Goo Cluster got its name.
The iconic candy from Nashville, Tenn., celebrates its 100th birthday this year. The confection of marshmallow, peanuts and caramel wrapped in milk chocolate may owe its longevity in part to another Nashville icon: the Grand Ole Opry.
Goo Goo Cluster sponsored the venue's radio broadcasts from 1966 until 2006. In one popular advertisement, stage performers crooned, "Go get a Goo Goo ... it's gooooooood!"
