The Dukes of Hazzard S06 E20 The Ransom of Hazzard County

"You're in Hazzard County where the lawmen are crooks, the good guys are outlaws and ever'body's in-laws!"

Fed up with the honest deputy Enos ruining Boss and Rosco's schemes, they promote him to a civilian job and replaced him with a crooked deputy who plans on Flooding Hazzard County by opening up the Hazzard dam unless Boss gives him all the county funds.
