Ding, Dong, the Boss Is Dead - S5.E15

A mobster named Calloway is out to exact revenge on "the fat water buffalo" (Boss), for sending him to prison on his testimony. To thwart Calloway's plans to have Boss killed, the Dukes and Lulu announce that Boss has died and stage a phony funeral so that Calloway will back off. But then Calloway arrives at Boss' "funeral" to make sure his old enemy really is dead, forcing the Dukes to come up with another plan to foil the mobster's plans.
