Plot hole: In the episode where Jessica went home to her family's house in season 2, Bill said "someone who lives here must invite me in." In this episode, Russell Edgington's wolf (Coota) invites Russell into Alcide's apartment. Also, in Season 6 Sarah Newlin recinds Jessica's invitation into Jason's house (which only Jason should be able to do).
Continuity mistake: The shots of Doran from his left rear shows him a couple feet away from the wall while frontal shots show him backed up against the wall.
Continuity mistake: Chase gives Zoey a radio in this episode, but in 1-3 Webcam, when Zoey, Quinn and Nicole are in Zoey's room trying to figure out who is telling the girls' secrets to people, you can see that radio above Zoey's head.
Continuity mistake: When Samantha is in the bathroom holding up two sample paint chips, in the first shot Sam is holding up the yellow in her left hand and the blue in her right hand, but in the next shot they've switched and are in the opposite hands, just as Jay arrives with the coffee.
Factual error: Wanda's father opens his briefcase of DVDs and one of them is Malcolm in the Middle. But the bomb that killed him fell in 1999, and Malcolm in the Middle didn't start airing until 2000.
Revealing mistake: The captain's arm that was removed can be seen wrapped in a green screen editing sleeve when he is in the hospital. (00:39:55)
Continuity mistake: Farzad JinJi is introduced as Dominque in the first season, but he appeared as a different character in the second episode.
Continuity mistake: During the photo shoot, after Tony takes the final shot and tells Margaret to "get dressed", so he can show her his place, she is wearing a different blouse and different earrings when she comes upstairs to his apartment.
My Sister, the Homemaker - S5-E12
Visible crew/equipment: At the beginning of the episode, Jeannie is talking on the phone by the stairs and her sister is hiding behind the banister. Her sister stands up for a moment and shows her full face, revealing that it is actually Barbara Eden's stand-in wearing the green costume.
Episode #2.7 - S2-E7
Continuity mistake: When Fidel and Dwayne arrive at the place where Camille and Richard are hiding for the hurricane, they can open the doors without a problem, whereas Camille and Richard had taken great care of locking the doors from the inside.
Deliberate mistake: Lily was an infant for all of season 5, but beginning with this season, she is around 5 years old. The show didn't jump forward in time, because JT states in a season 5 episode that he is 19, and in the episode this season where he and Rich go to Mexico, he states that he is almost 20, as well as Al and Mark are both still in high school.
Other mistake: Michael is 40 in Season 2 ep. 20 (Papa Said Knock You Out) while Jr. is 16 in ep. 19, which could not be possible since he had him when he was 16/17ish himself.
Continuity mistake: In the beginning of the series, Haley's big family is brought up often, implying that she has 3 brothers and 3 sisters. When her mom visits her, Taylor and Quin to announce that she is dying, there is no mention of or visit from any other siblings and Lydia talks about those 3 as if they are her only children.
Revealing mistake: S9 E1 "Bully for Ben": When Ben hits the punch bag sideways, it's easy to tell that someone is controlling the punch bag as it never slows down.
Revealing mistake: There are numerous times throughout the series where the supposed big city of Metropolis is actually just a back lot set and none of the buildings are more than a couple of storeys high. Quite often the green hills of Southern California can be seen beyond the set and between the buildings.
Father Frank, Full of Grace - S1-E12
Continuity mistake: When Steve gives Fiona the ticket to Miami he says it is out of O'Hare. When he goes to the airport he is at Midway.
The Spanish Inquisition - S2-E2
Revealing mistake: At the very end when The Spanish Inquisition bursts into the courtroom, you can see that Biggles is not played by Terry Jones (as he is playing the accused judge in the court sketch).
Character mistake: In the 11/14/2005 US Army Rangers report about Peter MacLeish, the word captain right under MacLeish's signature is misspelled "captian."
