Character mistake: While filming the cheerleader performance, Jasper refers to his inability of using computers ("We're gonna put this on YouTube as soon as one of us figures out how to use a computer!"). Earlier in the series, however, Jasper ordered himself a Russian wife online, so this statement is definitely off-character.
Character mistake: When Clark flies to see his parents for the first time, he is wearing a maroon shirt and jacket. When he lands at his parents farm he is still wearing his jacket and maroon shirt. In the next shot, he has taken his jacket off which now has a rip in the shoulder, as he enters the house his shirt is blue, and then in the following shot at the table having dinner his shirt is again maroon. (00:30:00 - 00:30:50)
Character mistake: Mike is holding and talking about his .59 caliber flintlock and refers to placing a percussion cap on it to fire it. A flintlock does not use a percussion cap.
Cat on a Hot Steel Beam - S1-E60
Character mistake: As the fire truck darts out from a back alley, the sign on a nearby gift shop window reads "gift's" when it should be "gifts".
Character mistake: Rufus says "That was before I found out you raped my 14 year old daughter." referring to Jenny. Jenny, in previous seasons is 15. Jenny was born in 1993, and season 4 was filmed in 2010, making Jenny 16 at least. (00:25:35)
Suggested correction: In this scene, Rufus saying, "my 14 year old daughter..." was referring to Jenny's age at the time Chuck tired to force himself onto her (beginning of the first season), not her current age in season 4. Jenny was 14 in the beginning of season 1.
Character mistake: When Betty and Daniel takes Oshie to the White Tassel, as they are walking in, Daniel asks Betty if she is sure that they do not have anything over $5, Betty smiles and agrees. However, when there is an establishing shot of the restaurant, it states in the window that there is something for $9.99.
Character mistake: At the start, when Adam messes up Johnny's hair, it cuts from him outside the dining room door to him at the dining room door with no time to sort his hair out but his hair suddenly becomes perfectly done. (00:01:36)
Character mistake: Eddie, Spudgun and Dave Hedgehog all appear worried at the fact that the devil takes "virgin's blood." However, it is apparent later in the episode that the 'devil' is in fact Dave Hedgehog's daughter, meaning he isn't a virgin.
Suggested correction: Also, Eddie previously slept with the Third Viscountess of Moldavia when Richie's back alley kidney donation backfired and he collapsed, so he wasn't a virgin either, but reacted as though he was.
Although theoretically correct, bear in mind that neither Eddie or Dave Hedgehog aren't particularly bright, and likely forgot they weren't virgins.
Hedgehog's daughter could have been adopted.
Character mistake: In the flashback of Mr. Mac Fist hitting Roger in the eye, the fist hits Roger in his right eye. Once the flashback ends and goes back to the present Keenan and Kel, Keenan says "My dad couldn't see out of his left eye for 2 weeks."
Character mistake: Marvin states Laurie's eyes are green, when in fact Susan Dey's eyes are blue.
Annette Castellano Is My Nemesis - S3-E2
Character mistake: At the end of the episode, Danny says "Can we not do this in front of Bernard King?" referring to a poster on the wall of Danny's childhood bedroom. We can see the player in the poster is wearing the number 15 and is actually Earl Monroe, not Bernard King who wore the number 30.
The Kidney's All Right - S3-E9
Character mistake: Arthur wants to donate his kidney to Derek. It is claimed that he must be a match since he has O negative blood, but blood type is not the only thing required for a kidney donor, there are several other factors that could very well disqualify his kidney for Derek.
Transformers (Lost episode) - S1-E7
Character mistake: When Donnie turns to the cameraman, Carl, and asks if he liked the film they just made, he responds in a normal American accent. Carl has been established in the series as German with a thick German accent, and the actor playing him, Rob, either forgot to use the accent or just didn't at that moment with them forgetting to change the audio in post. (00:03:55)
Character mistake: When Fiona and Ford are lying on the mattress looking up at the compass on the ceiling, the compass is improperly painted. With west on the left, north would be at the top, not the bottom as depicted.
Character mistake: Sue White suggests speaking in Portuguese but what she says next is actually Spanish. (The subtitles incorrectly say she is speaking Portuguese). (00:04:00)
Character mistake: Jessie's dance moves don't match what the other girls are performing, even though it's a choreographed routine.
Character mistake: When the sergeant's partner gets shot and Chen calls it in, she says he got away in a black Buick, but the car was a Honda Civic. (00:10:52)
Little Green Men and a Fella's Marriage Proposal - S6-E18
Character mistake: When Dr. Bell examines baby Constance, she has the stethoscope in her ears facing backwards. Also, when Sheldon and the professors are looking at the data from the telescope, Dr. Linkletter says "what about that" and Dr. Prakash says "no, that's within the standard deviation." That doesn't make sense.
Suggested correction: Not taking anything away from the other correction, but these are two separate mistakes put into one entry.
Character mistake: Bessie's last name is misspelled "Higginbottom" on the newspaper Happy shows her.
Kiss My Bum - S4-E10
Character mistake: Before Ellen invites Perry to thanksgiving there was only going to be seven for thanksgiving and yet whenever someone is asked about how many there are going to be at thanksgiving they answer eight.
