Girl Trouble / School Dance - S3-E18
Stupidity: Girl Trouble: Arnold somehow does not see the huge pile of glue that Helga put on his chair before sitting down. (00:03:14)
Suggested correction: Plenty of people don't look before sitting down. I once had someone put a pin on my seat in school and I didn't see it.
I can understand one not catching a small pin on their seat (or clear coloured glue). In fact, that is a pretty common prank. The thing is, Helga put a whole bunch of white glue on Arnold's chair, something so blatantly visible, unlike the other stuff I mentioned. It's just strange to me that Arnold wouldn't see something like that before sitting down in his chair. This also goes for my other entry that you added the same correction for.
Stupidity: When they are conferring before surgery everyone is keeping scrub except for Avery who has his arms crossed. Shortly afterwards you can see him look around at all his co-stars, realise he screwed up and try to casually raise his arms. (00:15:00)
Stupidity: After Bernie discovers a treatment for the infection, radiotherapy, everything goes back to normal. Except the contagion is airborne (which is why they were going to flush the entire ship's atmosphere), so they're just going to re-infect themselves in a few hours. And there's only one room on the ship that can be exposed to stellar radiation, so there's no way to clean the atmosphere either.
The Pin-Up - S7-E17
Stupidity: After Erin leaves with the military captain to Camp Lee, John and Maryellen turn around to see John Curtiss nowhere around on the porch where Maryellen left him. So John goes off to look for him, while Maryellen goes in to check The House. John Curtiss is a one-year-old baby who couldn't open a door.
Recognition - S1-E17
Stupidity: After fighting Wootox in Sky's body, why didn't Cruger contact the other Rangers and inform them about the body switch? This would have spared everyone a lot of trouble.
Those Are Strings, Pinocchio - S3-E22
Stupidity: Richard, an insurance man drove Rory's Prius graduation gift to Chilton. The car wasn't insured, and presumably wasn't registered. An insurance man who is anal about following procedure drove an unregistered and uninsured vehicle? Richard wouldn't do it. Plus, Richard should have mentioned transferring the title to Rory. Can't insure it until it's in her name.
A Deadly State of Mind - S4-E6
Stupidity: In the final scene: Columbo lays a trap for the murderer (George Hamilton). The 'eyewitness' when Hamilton fled the murder scene was a blind man. Hamilton is aware of this. Columbo's gambit depends on Hamilton's assumption that Columbo has coached the witness to act as though he was sighted so as to convince Hamilton that there is evidence against him. In fact, Columbo has the witness' brother, who is sighted, pretend to be the eyewitness and identify Hamilton as the man he saw driving away. When Hamilton falls for Columbo's trap and, believing he is in the presence of the blind man, tries and fails to 'prove' the man can't see. By doing so he reveals his knowledge that the witness was blind, incriminating himself. The problem is, that only a minute or so previously, Columbo had placed Hamilton under arrest, and failed to read him his Miranda Rights. Considering that Hamilton's slip up is the ONLY evidence Columbo has against Hamilton, this was a spectacularly stupid move on Columbo's part. Regardless of how many officers were present to witness this, the fact is that Hamilton was under arrest and had not been advised of his right against self-incrimination; meaning nothing that he said when under arrest can be used against him.
The Night of the Firebrand - S3-E2
Stupidity: West is introduced to, then knocked unconscious by Vixen as she hides a club behind her back. A trained Secret Service agent like West would not have let his guard down in this situation, as the entire fort was awash in bad guys.
Stupidity: The experienced cop Pullman enters the house of the well-known badass villain with her partner only, without any more backup. After the partner gets killed, Pullman stands free in the middle of the room without any cover - just 'begging' to get shot dead. (00:53:15)
Stupidity: For their set list at regionals, Schue chooses a medley of Journey hits. Since his kids are considered the competition's underdogs, and it was pointed out to him in the previous episode that Vocal Adrenaline's weakness is funk music, he should have used that info to New Directions' advantage.
Log 81: The Long Walk - S1-E14
Stupidity: They are looking for a red convertible. No other description of the car. A red convertible pulls up behind them and passes them. The ragtop roof is up but it's still matches the description. Doesn't faze them in the least.
Stupidity: The Kramden's door opens out towards the hallway. Yet anytime they need to block the door for protection, they put furniture up against it. That would serve no purpose, even with that cheap slide lock they have. The landlord or criminals could just open the door and push the furniture out of their way.
Stupidity: While discussing his arrest with Emily, Seth mentions that he didn't tell the arresting officer that he works for Kirkman. As the White House's liaison to the media, Seth has a high degree of visibility; it would extremely difficult, if not downright impossible, to keep his place of employment concealed from the police for very long in the time between his booking and arraignment and when Kendra bails him out the following day.
Stupidity: During the scene at the restaurant, Rose pulls the fire alarm. Then she and the doctor run through the kitchen, past several chefs who just duck and crouch into corners. This would easily be one of the stupidest ideas ever. If there was a fire, they would evacuate out the back door instead of just sitting there waiting to be choked to death. And if they knew about Auton Mickey, running out the back door would also be a lot more logical than just crouching down and waiting to be battered to death.
Stupidity: An RAF officer is wearing a gold stripe on his shoulder boards instead of blue. On his lapels, he wore a corporal's insignia, and on his left pocket was an American colonel 's eagle. A soldier described as British was wearing American platoon sergeant stripes.
