Other mistake: When Erin leaves The House to go with Ashley Jr., Elizabeth states to the kid that it's 3 a.m. When Ashley stops The Car to propose to Erin moments later, it is sunrise between the trees or early daylight, meaning this was a moment shot in different increments.
The Waltons (1972)
1 mistake in The Lost Sheep

John Walton: I hate this draft job, Liv. I can't stand playing God to my neighbors' sons.
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)
