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.
Other mistake: Lois digs up Chloe's grave site to unearth her casket. It is obvious that the casket is not buried six feet deep. You would think, with all that is going on, that LuthorCorp would have at least buried the casket deeper to deter inquisitive eyes and maybe throw in a few scattered bones for good measure.
Super Bike / A Mile in My Shoes - S2-E6
Other mistake: When Jorgen does wand-ups to Cosmo and Wanda, he counts 1,2,1,2,etc, yet when he does them to Timmy, he counts 1,2,3,etc.
Day 2: 5:00 A.M.-6:00 A.M. - S2-E22
Other mistake: In the beginning of the episode when the show is starting and the credits are rolling, instead of Billy Burke the credit is shown as Billy Gurke.
Other mistake: For secret agents, Sydney and Dixon are not very dedicated to secret identities. At several points they refer to each other by their real names in front of other people while they are under aliases. Examples include The Confession party and The Coup Las Vegas scenes.
The Breach - S2-E21
Other mistake: As Archer walks into the sickbay, while the camera pans, you can see a bottle of Crystal Geyser water. I noticed the bottle right away but had to pause it to see the brand. (00:39:00 - 00:40:00)
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 start of the line dancing scene where Ray Von is deejaying, if you have the subtitles on, it says the song is Hillbilly Rock, Hillbilly Roll by the Woolpackers. It's actually 5,6,7,8 by Steps. (I'm quite embarrassed I know that).
Other mistake: In the episode "The Mating Game," Ashley states, "Terry, sorry about last night." Unless she was with Jimmy and Ashley, because she is referring to when Ashley yelled at Terry. But that was 2 days ago, so why is she saying "last night" when it was 2 days ago?
Replacements - S1-E4
Other mistake: When Heffron is taking his throw at darts, he states that he needs a "double seven". When he takes the throw, the dart goes into the treble eight (an earlier close-up confirms that the board has the standard Gamlin configuration), yet, from the reaction he gets, he's made the throw he was going for. (00:04:40)
Injustice For All (2) - S1-E19
Other mistake: Unless he escaped prison, it makes no sense for Copperhead to be in the police van with the other Secret Society members. You can see him sitting there across from Solomon Grundy and The Shade.
Other mistake: In the inside of the flat where Jack and Victor dine with Frank McCallum, on the left wall there is a window on the left and a door on the right. However, this is impossible in their block of flats as we see in the exterior shots - there are no balconies and the layout of the building makes it impossible for a door and an exterior window to be on the same wall. From the cast commentary.
Misadventures in Babysitting - S1-E8
Other mistake: When Mr. McGuire is trying to get back into the house to check on how Lizzie is doing babysitting, the lock chain is on the door, so he grabs a saw to cut through it. He begins to saw it - however he forgot to take the yellow cover off of the metal blade. (00:18:40)
Other mistake: Nate has his pager with him when sitting his exam paper. The pager goes off and he takes it from his pocket and reads a message without any comment from the exam invigilator.
Other mistake: Two Tiffs can be seen for a few seconds when King Dedede and Escargoon drive in.
Other mistake: In this episode, Eric tries to destroy a mutant, apparently unaware that Rangers don't destroy mutants but freeze them. Yet in Quantum Quest and Clash for Control, he froze a mutant.
