Vampire Bats and Scaredy Cats - S2-E2
Other mistake: When the Mystery Company find a torn paper in a coffin, it is written exo-6 and something else. They find later that exo is the first part of exotic. The way the paper was torn, you should be able to see the lower part of the missing letters.
The Library - S3-E5
Other mistake: Dr. Mike spots a charred Bible within the charred piles of books, and heads into the church. The Reverend is giving a sermon on morality, and offers Dr. Mike the floor and she briefs about certain stories in the book, which would be considered scandalous, without mentioning the book's title, then hands it to the Reverend who agrees such stories are scandalous, until he turns it over, to see that its 'The Holy Bible'. Being a Reverend, he should know The Bible cover to cover, but reacts surprised or shocked over the mentioning of the scandalous stories. (00:36:00 - 00:41:00)
Other mistake: We see the letter about Merlin being written with a quill. However, despite the length of the letter being written we never see the quill being re-inked. (00:08:20)
Coffee Quest/Phoenix Rises - S1-E18
Other mistake: In Phoenix Rises, when Phoenix runs away, the Big Coffee sign is missing.
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.
Mind Your Own Business - S1-E35
Other mistake: Ralph gives Ed the advice to try to "squeeze" his boss for a promotion, but gets fired instead. When Ed comes home, he first stops in to see Ralph but he's not home, just Alice. All he tells Alice is that he had words with his boss and got fired. No details. Ed leaves and Ralph comes home. Alice tells him Ed was fired and described in detail the whole story of him threatening his boss for the promotion. Ed never told her exactly why he was fired.
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.
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.
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: Hannah Montana and Kyle (Lucas Cruikshank) are recording voices for an animated cartoon. The studio door is left open.
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.
Misadventures in Babysitting - S1-E8
Other mistake: When Mr. McGuire is trying to get back into the house to check on how Lizzie is doing babysitting, the lock chain is on the door, so he grabs a saw to cut through it. He begins to saw it - however he forgot to take the yellow cover off of the metal blade. (00:18:40)
Other mistake: When Scooby is eating the hot dogs at the "Hotus Dogus" stand, his tail goes transparent.
Other mistake: June Lockhart is referred to verbally as 'The Honourable Judge McKay', but the end credits say 'Judge MacBride'.
Other mistake: Carmine throws the gun on the couch and it goes off. The bullet hits in the opposite direction the gun is pointing.
Other mistake: In the episode where Tino is freaking out about the "FunVille" Arcade door looking like the mouth and face of a clown, it does. But in another episode I saw this morning (where Carver pretends to be all tough) the FunVille door is like any other normal door.
Other mistake: Lucy's drivers license says her birthday is in January but she was conceived on Valentine's Day.
Other mistake: When Roger writes the note after Kel glues his mouth shut, Kenan reads back far more than Roger could realistically have written in the short amount of time he took to write it.
Real or Robots/Special Delivery - S1-E9
Other mistake: Before Tommy and Chuckie climb up back on Stu's bed position, Stu's hair is orange, just like Chuckie's.
Other mistake: When Stacy sees Zoey's designed backpacks for the first time, she uses her camera to take pictures of them. In one shot, a close up of the camera display is shown and the message "CF card full" is on the display and yet the camera still makes "click" sounds as Stacy seems to take pictures. (00:10:22)
