I never saw that but I can guess how it went because the same thing happens to all situation comedies. The first 2 years are funny. Then they run out of material and the next two years are jokes about sex. Then the next 2 years are even nastier jokes about sex. The Dukes did the opposite. You never heard anybody joking about Enos's virginity or how many illegitimate kids Luke had, except in the first few episodes. You never see something get cleaner nowadays. I'm glad the Dukes did.
