Do You Take Dexter Morgan? - S3-E12
Other mistake: The marriage certificate for Rita's first marriage shows her date of birth as 04-19-1989 and Dexter states she married at 16. The marriage date is 08-16-1989, when she would have been 4 months old. She also would only be 17 at the start of the series (2006) if she was born in 1989. (00:13:45)
Other mistake: When they show the comic book and Hiro looks up the artist's address, it is listed as 215 Reed St. 7. The door to the artist's loft says his address is 681. (00:01:10)
Other mistake: The registration number of the Ford Zephyr police car is RVP154G but the security etching on the window reads EKM414C.
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: In episode 1x7, Barb has a list of all the family members' names and birthdays. On the list, the oldest daughter is a listed as "Amanda Henrickson". Her name is Sarah Henrickson: it's the actress who portrays her who is called Amanda (Seyfried).
Other mistake: In Season 2, Episode 14, "Double Negative" during the scene at the fundraiser, Kitty arrives and asks what the quickest way to a glass of wine is, to which Sarah (who is standing opposite her) offers her her own drink. Calista Flockhart (Kitty) does not see this, and another cast member attempts to take it from her, but Flockhart finally notices it and smirks at the realisation that she messed up.
Pool Party - S1-E2
Other mistake: After Cleo transforms into a mermaid, her wetsuit doesn't disappear for some reason.
Dedication - S1-E7
Other mistake: At about the 8 minute mark SnakeDoctor is talking on the radio to Bushmaster who is on the ground. There is a few seconds long shot where Bushmaster's earpiece is dangling wires and not connected to his Comms Gear on his vest. That earpiece can't be wireless.
Other mistake: Hannah Montana and Kyle (Lucas Cruikshank) are recording voices for an animated cartoon. The studio door is left open.
Other mistake: Near the beginning the dividing line in the bathroom has Henry on the right and Peter on the left but as you can see Henry would be on the left due to where his room is and where he would have to walk.
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)
Other mistake: The T.V. begins to work and you see a Chinese man with a map of the United States behind him. The cities that were destroyed were bulls-eyed on the map. Wichita was not bulls-eyed on the map, but Emily seconds later is crying in a car saying that her fiancee is dead because Wichita had been hit and she "saw it on the map."
In Too Deep - S1-E23
Other mistake: When Miriam tells Zane she will give him the necklace for a kiss, she said "I will give it to you." But then when she throws the necklace in the water, she said "I didn't say I would give it to you."
