light blue jeans. The exact hue of the shirt varied across the seasons - early on it was a deeper yellow; mid-run it was more of a cream color, and late examples saw it being more of a grey tone. The second episode produced and broadcast, "Daisy's Song", is notable for Bo instead wearing a red shirt for much of the story. A sequence in the fifth episode, "High Octane", sees Bo dressed in a light blue shirt, and many early publicity shots see the character dressed in a darker blue denim shirt. The character of Bo was best known for his rebel yell exclamation of the catchphrase, "Yee-Haa!"; cousin Luke sometimes also performed such a yell, but on a less regular basis. (Actor Tom Wopat had trouble mastering the high-pitched yell early on, and in the opening credits and many examples within the episodes, it is actually a recording of John Schneider's version used twice to represent both Duke boys' yell). Most of the time, it was Bo who drove The General Lee, with his cousin Luke riding shotgun (although these roles were swapped more regularly in later seasons); very early episodes suggested that the General belonged solely to Bo (Luke is said to have had a car that was wrecked very shortly before the start of the first episode, "One Armed Bandits"), but by mid-first season, it was more implied that both Bo and Luke owned the General Lee evenly between them. After Bo graduated high school in-and-around 1976 he became a stock car driver (though he joined the NASCAR Circuit for most of season 5 with his cousin Luke), and he was typically the one known for taking the General on most of its legendary jumps. Because its doors were welded shut, Bo and Luke always had to climb in and out of the car through the windows. Actors John Schneider and Tom Wopat have admitted that, on occasions that the roles were reversed and Luke drove, they found it much more difficult to climb in and out of the opposite window to which they were accustomed. Bo later left Hazzard County, along with his cousin Luke, to join the NASCAR circuit (coinciding with Schneider's and Wopat's decision to walk out of the show during the fifth season over a dispute over royalties owed to them), although how they managed to do this with the probation conditions
