Luke and Bo Duke were the cool country-boy cousins who raced about in their famous 1969 Dodge Charger, "the General Lee" avoiding capture by their nemesis Boss Hogg and his brother-in-law Sheriff Coltrane.
Most episodes of the Dukes of Hazzard featured a high speed car chase, lots of sliding across bonnets and jumping in car windows and an occassional visit to Uncle Jesse and cousin Daisy.
The Duke's car was very distinctive with a confederate flag painted on the roof and a horn that played the the first few notes of "Dixie" and was so popular that in the 80s it was quite common to see Ford Capris painted up with the flag on the roof or Ford Escorts beeping their "Dixie" horns at passers-by.
Sherriff Rosco P. Coltrane had a Beagle named Flash. Other characters in The Dukes of Hazzard were Crazy Cooter - who owned the garage in town and made a small fortune recovering police cruisers from Hazzard Pond, Deputy Enos Straight - who had the hots for Daisy (who didn't?), Deputy Cletus - who replaced Enos during the actors union dispute and occasionally Huey Hogg, the Boss's nephew.
During one season, there was a lot of industrial action in Hollywood and Luke and Bo were replaced by Coy and Vance - yet more Duke cousins.
