Factual error: When Elizabeth asks Zeb how Vanessa can be happy, Zeb has his old catalog with a bunch of flower seed packets on his lap, and as they both hold up the packets, particularly Elizabeth, the modern Universal Product Codes are at the back of the packets. The UPC did not exist until many years later. (00:10:05)

The Reunion - S1-E14
Ike: How's it feel to be a working man?
John-Boy: Ike, Mama would skin me alive! Everyone knows those two ladies make bootleg whiskey.
Ike: But they don't know what they're doing. They're just following their papa's Recipe.
John-Boy: But sometimes they sell it!
Ike: Yeah, but they're just like two little girls by a roadside selling lemonade.
Trivia: While John is reading the newspaper funnies to John Curtis, we hear Erin and Mary Ellen come home, so John puts the folded newspaper down on the couch. And as the newspaper lies on the couch, we can see the large white adhesive label with typewritten sentences adhered to the center of the funnies page. Presumably, these are the actor's lines as he was reading quite animatedly to the toddler (sweet moment). (00:06:25)
