Does anyone know the origin of the term "gorilla bread" or "monkey bread"? Is it a Southern thing?

"Gorilla bread" was recently featured on an episode of "Paula Deen's Cooking" on the Food Network. Paula visited Jimmy Carter in his hometown of Plains, Georgia and prepared this breakfast pastry for him. It looks REALLY good, but they never explained the origin of the term.
