Visible crew/equipment: At the mill, when John tells Buck that Willie Brimmer might be at the Montgomery cabin with Jim-Bob, in the next closeup of John we see a billowy trail of cigarette smoke at the bottom right corner of the screen, but the only people standing there are Elizabeth, John, and Buck, and none are smoking. Presumably, it was someone offscreen smoking too close to the camera (similar to a mistake in 1978's "Halloween"). (00:26:05)

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 everyone is at the table eating supper and talking, little John Curtis taps on John's shoulder, then John turns and asks "What?" John Curtis points to his pants and excitedly says, "I got new pants," and John says, "I see that. Who got you those? Your mommy?" Then John Curtis looks offscreen, away from the other actors on set, and replies, "No, from Pat," (no characters named Pat are on the show) and without missing a beat, John responds, "From Pat? Where does she live? On the next farm?" And John Curtis answers, "Yeah," amidst all the giggles we can hear, so John answers with a smirk, "Okay, good!" This is such a hilariously precious unscripted moment, and great they decided to leave it in the episode. (00:26:15)
