A long time ago, in a galaxy far, far away, Chewbacca was a wookiee. He was friends with Han Solo and a tough cookie. Now, in this galaxy, Chewbacca is a can of Coke Zero. He is friends with your waistline and is a can of Coke Zero. (More like Sipbacca). You can say he went from hero to zero — Coke Zero, that is. Times, they are a-changin’; wookiees, they are a-becomin’ cans of Coke Zero. Coke Zero!
