I am 35 years old. I love the dukes. And have since I was a little kid. Which kind of leads me to my question. I have a memory of a Dukes episode where Bo and Luke are standing back talking about something and looking at a sign, or maybe a barricade? One of the boys, Bo I think, walks up and unscrews something with his knife. I know that's not much to go on. I have seen most all episodes many times since then. But I have never seen whatever this was again.
