Other mistake: 1967: Burke mangles his line to Vicky, and instead of telling her to get off her history kick, says, "I just think you should get off that hickory stick for a while."
Other mistake: When Rube is searching the hard-copy (paper) archives, the young man with him opens the last box and pulls out an old "Wanted" poster with Rube's face on it. He tells Rube "This guy looks just like you." Since season 1, episode 1, we've known that Grim Reapers don't look like they did when they were alive (i.e., Millie/Un-George). Yet somehow, Rube has not changed since his life/death.
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: In the party/orgy scene where Aetius is showing off Rome to Attila, one can see a woman with her back to us reveal herself to a man and woman. Despite her veil, one can see her thong underwear. This type of underwear is a 20th century innovation.
My Overkill - S2-E1
Other mistake: When JD and Turk get coffee from the street vendor, Turk tips the cup at an angle which shows they are empty as it doesn't spill.
Other mistake: At the beginning of the episode, Abby is almost run over by a man driving an SUV. They exchange words and then Abby throws a supposedly full cup of coffee at him. The cup of coffee bounces off the seat of the man's car and it is obvious that the cup is empty.
Other mistake: House has Metroid Hunters on the DS next to the gangster's ear and it shows Samus in a ball rolling around. The way she was rolling couldn't have been achieved because House was holding it, his fingers nowhere near the buttons on the game.
Other mistake: In the summer of 2004, in Puerto Arena, Paloma met a man, Nick, who told her that Luis and the other Lopez-Fitzgeralds were just trying to use her, and didn't really love her. Later that night, Nick kidnapped Paloma and tried to rape and murder her. She stopped him by bludgeoning him with a rock, and later throwing him into a support pillar that resulted in a structure collapsing on him and presumably killing him, before reuniting with Luis, Sheridan, and the Wheelers. And yet that fall, after she had returned to Harmony, Paloma flashed back to what Nick had told her and behaved as if she believed what the murdering rapist had told her about the people who ultimately rescued her from him.
Other mistake: The registration number of the Ford Zephyr police car is RVP154G but the security etching on the window reads EKM414C.
The Night of Miguelito's Revenge - S4-E12
Other mistake: The sandbag that almost falls on Pike and West splits wide open upon impact with the floor, but subsequent shots of the bag show it almost intact.
Other mistake: The bullet they pull out of Bobby is the entire bullet, casing and all, not just the slug.
Other mistake: Carrie the assistant brings Lisbon and Jane to Stutzer's office. She swipes her card to open the door. However, she does this upside down, swiping the bar-code instead of the black magnetic strip, on which she is holding. (00:09:30)
Other mistake: In the beginning when Kali and her gang are running from the police in Pittsburgh and she "collapses" the tunnel, her 008 tattoo is shown this way so we can read it as such, but it should in fact be read 800 to be the correct way. (00:03:15)
Other mistake: The excavator with the rotating bucket wheel that is shown in the opening is turning backwards from the direction required for it to actually dig.
Other mistake: Right after Sam tells Carla he will sleep with the next woman who walks through the door, in the background there is an "Extra" (blonde-haired woman seen in the background behind Carla) who starts to cross right then turns and crosses left then turns right and stops and looks confused as to where she is to cross. Obviously she was given directions of which way to cross and when, but forgot. (00:04:15)
Other mistake: Slightly after the opening credits, Jack Malone is investigating the disappearance of Annie Miller and is standing in her mother's bedroom. He turns to Carol Miller's boyfriend and asks to "speak to Mrs. Malone alone." The subtitles correctly have 'Miller' written, but when Anthony LaPaglia says his line, the two words rhyme. (00:06:45)
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: The Doctor scrubs his hands before an operation. He should not have to do this. He is a hologram. He could just dematerialize himself and be rematerialized if he's concerned about contamination.
Suggested correction: Maybe dematerializing and rematerializing would waste too much energy.
Other mistake: When the opening credits are shown, the door to the basement is in the kitchen. In the beginning of the series the door is still in the kitchen, but in later seasons the basement door is in the laundry room, but in the opening credits it is still in the kitchen.
Suggested correction: I had noticed the same thing and thought it was a continuity mistake. However, in Season 3, Dan mentioned building the back service porch where Roseanne does the laundry. There are two basement accesses, the one in the kitchen, and what was probably the outside entrance in the backyard that is now enclosed inside the service porch. The family prefers using that one. Most houses, mine own included, have multiple basement access, one inside the house and one outside. In my state, it's a building code requirement for safety reasons.
Disharmony - S2-E17
Other mistake: At the very end, as Angel walks out the door he reflects in the panes of glass on the door. (00:42:10)
