The Hack of Hazzard - S3.E22

While she's away, Bo and Luke run a taxicab service owned by Miz Tisdale, and their first customers are two men with a special briefcase. After arriving at their destination, the two men leave a stolen gold certificate in the back seat of the cab and try to retrieve it without getting caught. Boss Hogg, meanwhile, wants to make sure the briefcase is still in the cab when federal authorities arrive--the main goal (of course) being to implicate Bo and Luke.
