Feud for Thought is a 1963 Deputy Dawg cartoon.
Things are just too quiet in Deputy Dawg's territory till a feud breaks out between the Hatefields and the Le Roys. Feuding hillbillies shoot the car out from under the sheriff, who orders Deputy Dawg to stop the feud. He demands that Deputy bring them in to jail. Deputy would rather give up his job. Deputy steals the hillbillies' guns and replaces them with watermelons. The feud continues with them throwing watermelons- one at the sheriff.
