 During the CBS network run, the closing credits showed Andy and Opie walking  back from their fishing trip. Opie drops the fish, and runs back to get them.  One of the original sponsors products (Sanka coffee, for instance) would  appear in the corner of the screen. The syndicated reruns show a plain gray  background (or blue, during the color years) with a drawing of the town  square in the corner of the screen that once displayed the sponsors product.
