Plot hole: When Two-Face and his men have broken into the new D.A.'s office to find dirt on Rupert Thorne, one of his men finds a file detailing Thorne's record of Swiss bank accounts, money laundering, blackmail and payoffs that Two-Face tried for years to subpoena when he was D.A. When Thorne finds out that Two-Face has the file, he states that he will be ruined if Two-Face gives the file to the police. If Two-Face tried unsuccessfully for years to subpoena the file, then in all likelihood that means Thorne paid off the right people to prevent the subpoena from happening, so Two-Face giving the file to the police shouldn't be a problem for him. Additionally, if giving the file to the police would be all that it would take to bring Thorne down, then the new D.A. could have already done so. If the new D.A. was also paid off by Thorne, then it wouldn't make sense for Thorne to allow the D.A. to keep the file since they could easily lose the file or even double-cross Thorne.

Tintin and the Picaros: Part 2 - S2-E9
Plot hole: When the helicopter flies over the jungle, Haddock inadvertently walks in view of the helicopter and the pilot of the helicopter notices him, assuming it to be a Picaro. Haddock then trips into the river, but despite being watched by the pilot of the helicopter the entire time, the helicopter pilot doesn't notice him falling into the river and instead assumes he just disappeared. (00:26:20)
Plot hole: Dumb Donald chooses not to play hookey with the rest of the gang. He instead goes to school. The gang is even worried Dumb Donald may, "Rat them out" to the school. Yet throughout the episode, Dumb Donald appears/disappears with the gang as they are skipping school.
Attack Of The Mutant (1) - S2-E2
Plot hole: Skipper spots the Masked Mutant's headquarters the first time he goes past. He then goes back the next day, and the headquarters have vanished. He then goes back a third time, and the headquarters aren't there yet again. However Skipper says "How can it be. It was right here yesterday," although it wasn't.
Plot hole: There is no way that Zoey could've seen those boys hanging Chase's bike from a tree. She was way far from the window to even recognize his bike, and when Chase looks through the window, the bike was just now being lifted from the ground.
Plot hole: Guards at a security checkpoint attack Varrick and Bolin, because a wanted poster identifies them as fugitive traitors. The problem is that poster cannot have been there. Varrick and Bolin escape in the previous episode (Battle of Zaofu) but are captured minutes afterwards. (So, no posters needed.) The next day, they escape again by blowing up their imprisoning train car. Their captor, Bataar, thinks they are dead. Indeed, Varrick intended to die. Later, Bataar is actually shown reporting them dead. One might argue that the poster wasn't a wanted poster, but one that warned people about the empire making an example of the traitors.This argument is too flawed: The empire had many examples already, some very high-profile. And a propaganda poster must be placed in plain sight, not in a security booth corner especially designated to let security guards compare the passing individuals. (00:14:00)
Plot hole: Kenan ends up out of the door when trying to persuade the robbers not to give. Surely with all the media attention, a camera would have spotted him, and his family would realise it's Kenan. (00:20:30)
Plot hole: When Justin and Juliet were trapped behind the glass and Juliet let herself be captured by the mummy, so she doesn't burn to ashes when the morning comes, why didn't Juliet just escape? The mummy gave her enough time to turn around and share a moment with Justin, she could've used that time to fight him off, break Justin out and escape. The mummy wasn't very strong and Alex would've shown up 20 seconds later anyway, there wasn't any real reason for Juliet to just let herself be taken away.
Plot hole: In the ending scene, Mike has a probable concussion from her fall, so Sully keeps her awake to prevent her slipping into a coma. They talk all night, reminiscing as Mike experiences periodic pain spasms. Their talk ends with discussion over them having another child, and then they instantly engage in an intimate moment, which would be impossible, considering her condition, and without further checkup from another doctor. Sometime later she is suddenly feeling 'cured', and they return home.
Plot hole: Cleo's photo album contains photos of her and Lewis from past episodes ("Love Potion", "Doctor Danger" and "Hocus Pocus"). It's impossible that their photos could have been taken because they were alone in all of them. (00:03:07)
Plot hole: This was the first episode of the series and we see that the rangers are unable to figure out how to properly operate their zords; but in Origins Part 1 (which takes place prior to this) they have no issues with the zords at all.
Plot hole: During "the changes" people fear machinery, but the woman who pulls back her curtains to watch Nicky and the sikhs go past is wearing a watch.
Plot hole: The Jupiter 2 crew is duplicated; however, the aliens had never seen Penny (or Judy I think). How can they be duplicated? The aliens don't have ability to know who were there, or they wouldn't have questioned Smith about the crew. Also, they do not know Smith and Will are hiding. So, they don't arm to have any special power to know beyond what they actually observe.
Plot hole: Tim has the mike in his hand and steps repeatedly forwards to talk to Jill, the cord being long enough to allow him to do so. However once Jill leaves and he wants to go after her the mike knocks over the jar of mosquitoes. Up until then, there was no indication that the mike had been changed or moved but he never at the risk of knocking over the jar until then.
A Scooby-Doo Valentine - S3-E3
Plot hole: It's never explained how JC Chasez and the Hollywood extras impersonating the gang gained the super strength they possessed to do things like ripping car roofs open or holding up the Mystery Machine.
Plot hole: Rick is taking care of his girlfriend's goat for a few days. He puts a bowl of milk on the floor, but The Goat will not drink. Harriet suggests, "We're probably just using the wrong method." The next scene shows Ozzie at the stove, heating milk in a baby bottle. Rick is 22 years old. Why would Ozzie and Harriet still have a baby bottle in the house?
Plot hole: The whole episode is based on false facts. Cody was getting an A in woodwork and Zack was failing in all his classes the previous year at school (according to their report cards in Ep "Smarter and Smarter"). So Cody knows a lot more about woodwork than Zack and should be able to make a clock, never mind a birdhouse, and Zack should not be able to make a clock.
The Tale of the Mystical Mirror - S5-E3
Plot hole: It makes no sense that Ms. Valenti gives all of her employees a compact mirror and also invites them to her home. Any of them could open their mirror while standing near a painting of Ms. Valenti and they would discover the secret, as Cindy does.
Suggested correction: The compact mirror includes a palette of cosmetics. Cindy shows it to Laurel, who says, "She gave one to me, too, like we're ever gonna use it." Presumably, the employees are mostly using the free samples of cosmetics from the shop displays. I myself have owned some compacts that I didn't always want in my purse (if they were too big or awkward in a certain purse).
