Barbarosa for the general idea. Old outlaw Barbarosa--Willie Nelson(!)-- hooks up with punk Gary Busey. Everyone knows Brabarosa is a villian, even though he was old when flowering plants appeared. The villagers nail Barbarosa, and then go into a funk because there's no one to fear. Busey shows up and shoots someone's hat off, and there's about 5 seconds where everyone stares, and then they start yelling "Barbarosa!" and chase after him. They're all overjoyed and angry as they take off after him.
