After Sideshow Bob Roberts, this is the second episode that featured no chalkboard gag or couch gag in its original airing ("Sideshow Bob Roberts" originally had the short opening on its original broadcast, but has the very short opening on repeats). However, unlike the former, this episode is missing the opening sequence altogether, with the credits that would normally appear on the TV appearing as subtitles during the first act.
This is one of the several episodes to be rated TV-14.
FOX Broadcasting Company said that this episode was running too long, so they chose to skip the opening sequence. Instead, it begins with the Simpsons going peach farming, marking this as the fourth episode to not have the sequences, along with "Bart the General", "Life on the Fast Lane" and "Sideshow Bob Roberts" (repeats only for "Sideshow Bob Roberts"; that episode originally used the short opening on its original broadcast)
According to Marge, they had to pay for the peaches they take home, so Homer could have left the peaches in the farm without having to pay for them.
When Lisa does the milk trick, Nelson is seen telling God, "God, if you don't bring my Lisa back safe, ants will burn tonight!" This is from when the pair dated in "Lisa's Date with Density". Clearly the writers wish to remind us that Nelson still has feelings for her 14 seasons later.
When Ewell takes the guitar to play it, the pegbox goes through his face.
When Lisa goes out of the bush, one bush has a different green tint.
When Marge lays again on the massage bed, her left arm becomes of a dark yellow tint.
When Bart walks on the corner, Dolph does not have his fringe. Later, it reappears.
When Raymondo opens the sarcophagus, the pommuls of the swords cannot be seen.
After Lisa says "Looks like there's magic between you two", Raymondo and his wife in the photo don't have pupils.
It is unknown why Marge does not say something after Lisa and Bart throw away the peaches. Although it could be that she grounded them offscreen.
