Yes, there were a couple reasons. First, Sonny (Enos ) had a return clause in his contract, if his own spin-off series "Enos" failed. It did. So for the first few eps of Season Five, Enos returns while Cletus is still around, and we get to see them on duty together. The episode, "Coy Meets Girl" is the last episode to include Cletus. Rick Hurst left Dukes in order to take a role on a new CBS series. Unfortunately Rick's new gig cancelled within 3 months. I always thought Cletus was a lot of fun to watch. It's a shame the Hazzard payroll didn't allow both deputies to remain. Brian
