I knew the name, and got the pun, but never saw the show.
In the Netherlands, we had our own version with the movies and TV show Flodder. The titular Flodder family weren't farmers, but, well, white trash would be the closest comparison, who got to live in a generic high-class neighbourhood when the city council found out their old home was on top of a toxic waste dump. There were some differences, mostly in that unlike the Beverly Hillbillies the Flodders, particularly the oldest son and 'protagonist' Jonny, were small-time criminals. And rather than any overly honest or practical mentality, it was often their crooked schemes that got the plot rolling. But what it does have in common is that while the show did portray them as crooks, they tended to more sympathetic than their upper-class neighbours. They tended to be a lot more relatable than the hypocritic and posh people who surrounded them, especially in the movies.
