Deadeye Dick - S5-E9
Visible crew/equipment: In the scene where Trampas says, "You can bet no matter what happens, I will be blamed for it," as Sara Lane turns to ride away you can see a Chevy truck for about four seconds. The time left on the counter is between 29 and 28 minutes.
Audio problem: Season 3, Episode 68, "The Duel". Sometimes the tank's co-axial machine gun is firing, but no gunfire sound is heard.
Factual error: In the opening scene, the Clampetts are driving home from Malibu. From Malibu to Beverly Hills is east. But as they head home, the ocean is on their left, which means they are driving west.
Revealing mistake: When Albert and Harold are fighting over the cracker Albert's face goes into the trifle, and if you look carefully we can see that he just lets go of the cracker and puts his head in the trifle deliberately.
Water's Edge - S3-E3
Factual error: Pete Taylor's corpse is a bare skeleton after just two years in the sea-shack's attic, though it shouldn't be. There should at least be traces of hair and clothing surrounding the bones. (00:40:00)
Continuity mistake: Halfway through the show, they get caught not having the boat, and McHale gets taken by boat to the commander's office. As he leaves the pier, he drops the rope on the seat next to him, they do a close-up and the rope is behind him about 5 feet away.
Continuity mistake: We see that the XL18 pilot is sitting in the right seat of the cockpit. In the next shot he has changed to the left seat.
Revealing mistake: While Lucy and Vivian are on the boat we can see the two long tracks on the floor in the boat's galley, so when Viv falls asleep in the chair she brought from home, the chair legs are able to keep gliding along the tracks on the floor from one side to the other. (00:19:45)
Audio problem: When Judy asks "But Grandpa, why didn't you tell us what was going on?" towards the end of the episode, she is speaking with Jane's voice.
