Come Back, Little Googie - S1-E25
Other mistake: When Eddie's naughty little friend goes to shake hands with Herman they insert a quick close up of a hand buzzer in his hand, only it's obviously an adult's wrinkly hand.
Other mistake: In the inside of the flat where Jack and Victor dine with Frank McCallum, on the left wall there is a window on the left and a door on the right. However, this is impossible in their block of flats as we see in the exterior shots - there are no balconies and the layout of the building makes it impossible for a door and an exterior window to be on the same wall. From the cast commentary.
Dutch Art and Dutch Courage - S7-E4
Other mistake: At the start just before Michael gets out the car, he puts the handbrake on, but the car carries on moving.
Other mistake: Kenneth Cope had to wear a toupee for his part. He did so, only it was initially on the wrong way, though no one pointed it out or noticed. If it ain't broke...
Other mistake: Just as Brian Damage says, "Oh, weren't ya?" to Neil, you can see the shadow of Neil's mother on the front door, awaiting her cue to come in.
Coffee Quest/Phoenix Rises - S1-E18
Other mistake: In Phoenix Rises, when Phoenix runs away, the Big Coffee sign is missing.
Love and Other Four Letter Words - S1-E12
Other mistake: Right at the end of the scene, when Christa is screaming after she sees the mouse in the hut, watch as the shot fades out into the next one she starts laughing.
Other mistake: When the interviewer asks the girl what she was doing March 15th, 2016, she says she was shopping. However when the receipts are shown they say 05/15/2016. (00:10:50)
Dave and the Teenager - S11-E17
Other mistake: When the Harris family moves into an apartment across the hall from David and June Nelson, their 14-year-old daughter, Betty, develops a crush on David. When David and June step out onto their outdoor patio, they see Betty watching them from her own patio. This could not be possible.
Farnsby & B - S1-E18
Other mistake: The ghost in the Farnsby's house knew Ronald Reagan as an actor but in 70 years she didn't know he was elected President even though she would have heard about it from people who lived in the house during his terms.
Other mistake: When Viper slides the swords to Jackie and they come to a rest next to him, there is a small paper spider right beside Jackie. The only paper spider in the room, however, is Origami himself, and he is actually too far away at that moment and too big to fit the bill. Guess some of the animators got their depth perception messed up.
Blödeln auf die feine englische Art - S1-E2
Other mistake: In the "Happy Valley" segment, when the witch is just about to enter the cathedral, you can see a car drive past through the windows behind the altar. (Now, this is Monty Python, so we have to be careful... But is isn't clear, or funny, enough to be there on purpose).
Christmas Special 1974 (a.k.a. A Perfect Christmas) - S8-E7
Other mistake: Just after Albert pulls the decorations down, Harold yells as he pricks himself on a nail sticking out of the ladder, however he completely misses the nail.
Funeral at Fifty-Mile - S1-E22
Other mistake: It's a clear day not a stormy night as it should be when showing the barn in the flashback. Look closely and you can see a clear sky through the barn walls cracks.
Did the Earth Move For You? - S2-E1
Other mistake: Viv and Phil are waiting in his office for the power to come back on after the earthquake, but you can see lights on in the building across the street. (00:16:30)
Other mistake: During the 3-nightmare sequences, there are 25 students, with all desks full. However, 1 desk should have been left open as Kevin appears in the dreams, meaning there should only be 24 students.
Other mistake: In the scene where the Glee Club is discussing that Violet will win them the contest, Violet leaves as she is upset about Screech. Zack then comments about "No one having a voice like Violet's". If you look at Mr. Tuttle, he mouths the words that Zack says.
Other mistake: Hannah Montana and Kyle (Lucas Cruikshank) are recording voices for an animated cartoon. The studio door is left open.
Other mistake: When Mattie first gets her kite out, Richard says that they are in the same fjord where Jeremy and James went through the ice. If so, the scenery has changed remarkably in a couple of days. All the blue ice is gone and so are the cliffs, which prevented Jeremy and James driving out. He can't have taken a different route as the fjord is only a mile wide.
Other mistake: During the first dozen or so episodes, during the opening credits, Onizuka is shown spray-painting a picture of a woman on a wall, with the words "Love" and "Piece" written next to her. Obviously, "piece" is a mistranslation, and the wrong spelling. The correct text should read "Love" and "PEACE."
