Other mistake: In this episode, Shawn supposedly impresses Jules at their first meeting by "divining" facts about her family and cats. We never hear about the cats again and later learn that her parents have not been together for 30 years.
Other mistake: Captain Eureka losing his finger makes absolutely no sense. He doesn't cry out in pain, there's no blood, and where the finger ended up is completely illogical. The finger didn't just sever on its own; it's shown that severing only occurs when passing through objects. Captain Eureka goes through a wall that is a good fifteen feet away from where the finger is discovered, and it is implausible to think it could have rolled there on its own.
Other mistake: When Jen gets into the elevator, it says '34th floor.' However, when Jen looks at the panel with the numbered buttons, the numbers only go up to 31.
Other mistake: Hannah Montana and Kyle (Lucas Cruikshank) are recording voices for an animated cartoon. The studio door is left open.
Horrid Henry and the Dinner Guests - S1-E17
Other mistake: When Henry's parents run into the kitchen to get Mrs. Mossy cleaned, Henry's neck is miscoloured for a split second. (00:07:19)
The Courtship of Betty's Father - S3-E14
Other mistake: When Betty is waiting at Elena's home, Elena walks up carrying a bag filled with groceries, and during their conversation we see the box of Nabisco Thin Crisps and bag of Goya Plantains in the grocery bag. Note the "Nabisco" logo and the brand name have been covered on the box, and there are strips of white tape disguising the brand name "Goya" on the bag. (00:36:10)
