The Dukes of Hazzard S04 E19 Nothin' But the Truth

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

When Boss Hogg learns that a state investigator is on his way to Hazzard to check out a claim of an illegal casino, he shifts the blame to the Duke family. But just as the Dukes are being formally charged, Boss sits on a syringe filled with truth serum. Boss lets slip the truth, and his cronies are none too pleased, forcing Bo and Luke to ride to Boss' rescue.
