Visible crew/equipment: When Mork and Mindy are walking away from the lake after they first meet, there is a set of 8 lights in two rows of four in the background.
Unicorn Club/Go Gomez! Go! - S1-E2
Continuity mistake: When the cats are entering the race the height of the sign lowers when Waffle walks up.
Continuity mistake: Just after Otis makes the ghost sounds from inside the house, it shows the gang standing together outside the house. Otis is with them outside, which is impossible, as he is inside the house pretending to be the ghost.
Diana Ross - S4-E23
Continuity mistake: When Diana Ross finishes her first song, the bird has both his feet on the ground; in the next shot, the bird has one leg raised, without enough time passing to do so. (00:08:45)
Fiend is Like Friend Without the 'R' - S1-E4
Continuity mistake: Mandy hits a baseball with one of Grim's bones, yet when we see Grim, there are none of his bones missing from his body.
The Secret Of The Juice - S1-E10
Continuity mistake: When Tummi goes looking for Zummi, Gruffi and Cubbi, he arrives right outside the barrel room. When first seen, the barrel room door is smooth, but in the next close-up the door suddenly has an iron grill window in its surface.
Half-Baked - S2-E2
Continuity mistake: There are three boxes of cupcakes stacked on the coffee table. However when Trixie picks them up, as the shot changes there are now five boxes of cupcakes. (00:12:10)
Continuity mistake: In the scene where Mr. H. Makes Bloo wash his hands, Mr. H takes off his gloves and washes his hands then dries them. Notice that as soon as he takes his hands out from underneath the towel his gloves are back on.
Revealing mistake: As Delta Tango 19 takes off from the airport, there is a shot where it is actually landing. This can be seen from the fact that there is no runway behind them, as it is in front of them.
Heart of Ice - S1-E3
Other mistake: When Batman is watching the security footage of Victor Fries' accident, at first Fries is addressing the camera directly which follows him and pans according to his movements and Ferris Boyle interrupting him, which would suggest a second person was in the room with a handheld camera. But after Ferris Boyle enters the room and orders Fries' experiment terminated, there are several cuts from various angles in the room suggesting surveillance cameras. The surveillance style footage also often conveniently cuts to the face of whichever person happens to be speaking or will cut to a certain angle in order to put emphasis on the action, all of which would require multiple mounted cameras and purposeful editing by either Boyle or one of his subordinates, which would be completely illogical since they don't want anyone to see the footage in the first place. (00:12:20 - 00:13:55)
That Little Old Matchmaker, Martin - S1-E12
Character mistake: In Bill's office, after Tim talks about the acoustics in the building, Bill calls Tim "Bill." (00:15:51)
Character mistake: When Alex mentions to Mallory that he's had sex before, he tells her he was 17 and that it was leap year. Not correct, this event occurred in 1982 (during one of the first episodes when Alex was 17), which was not a leap year.
Sky: Part 1 - S5-E1
Continuity mistake: The baby carrier little Sky is in as the group heads towards the car changes between takes. When they are walking down the driveway, it is open, and Sarah Jane quickly closes it when Gita comes up. Gita opens the carrier, to discover the baby, and Sarah Jane closes it again. There is more dialogue and Gita goes back to cooing at the baby. When did the carrier open again? Then the car alarms go off and if you look closely, you can see it's closed again, which is confirmed when the baby is handed off to Clyde.
Revealing mistake: Very obvious copy and pasted dogs (even standing in the same position) whenever there's a general view of a crowd in the main hall.
Neogenic Nightmare Chapter 11: Tablet of Time - S2-E9
Factual error: When Peter is walking Alissa home, the traffic signal at the intersection they stop at goes from red to yellow to green. Not what US traffic signals do - they go straight from red to green.
Suggested correction: Not entirely true; although they are rare and may no longer exist now, I've seen traffic lights that followed the red, yellow, green pattern as recently as the mid-1990s.
Interesting. What state (s) did you see this in? I'm assuming going from red to yellow was to encourage cars to cautiously enter the intersection in case someone was running a red light?
Traffic lights in the UK do this - it's more to give you a second to get ready, in gear, etc., then as soon as the lights turn green you can go. Otherwise you get no warning of when the lights are about to change.
In Illinois; as I said, such traffic lights are rare, but they did exist at least as recently as the time this episode of the series aired, and they may still possibly exist in larger cities such as New York City.
This traffic light set-up (red to yellow to green) still exists today in the UK. From what I understand, it is to alert the driver that the light will be turning green imminently and to prepare themselves to put their car in gear, as manual cars are still pretty common in Europe. I'd wager this light cycle was phased out of North America due to the abundance of automatic cars today. Could have been different in 1994 though.
It should be noted that traffic lights that go from red to yellow before going green keep the red light illuminated so that both red and yellow are lit up. However, that's not what happens in the scene. I've never seen a traffic light operate the way it's shown. And Massachusetts still has traffic lights that go from red to yellow, however, when red and yellow are lit up together, this allows for pedestrian crossing.
Visible crew/equipment: When Kathryn tells John that staring at his phone won't make it ring, in the next shot facing John the boom mic can be seen in front of him, bobbing around at the top of the screen. (00:02:55)
Other mistake: A time card reads 6,000,002 BC, when it should've read "60,000,002 BC". (00:07:12)
Continuity mistake: When Lin lifts the rocks around the house in the final scene, there are eleven of them. But in the last shot, there are only eight rocks.
The Robbery - S4-E4
Plot hole: Towards the end, Jake (Shirley's boyfriend), hangs the girls on a coat rack by the hoods of their coats. They try a few comical ways of trying to escape, when they could have simply unbuttoned their coats and slip away.
Episode #2.8 - S2-E8
Audio problem: When Cathy and Trisha are walking to the post office with Mr Hargreaves walking behind them their mouths are not moving in sync with their dialogue. (00:09:55)
