Stupidity: After the accident, Dawn is in spirit form on the road trying to wave down an oncoming car (driven by Martha Kent). Dawn doesn't know she's a spirit that can pass through objects at that point. Since Martha can't see her, she keeps driving straight towards Dawn. Dawn sees the vehicle isn't slowing down and instead of simply stepping out of the way to avoid getting hit, she turns her back, revealing to the audience that objects can pass through her now.
And All Through the House - S1-E2
Stupidity: The woman could've blamed her husband's death on the maniac, she didn't need to go outside to retrieve his body.
Stupidity: The fact that the young mother in the hospital would give Janet (a total stranger to her) her baby to watch while visiting her husband in a different area is completely unreal. Nobody would really ever just give their baby to a stranger like that and leave. In addition, Janet took the baby into Jack's room for quite awhile.
Stupidity: Yoshi, Mario's sidekick who constantly follows him on dangerous adventures and has gone on dangerous adventures by himself, gets scared shitless when confronted by Riptor. This is not how Yoshi would act in a situation like this.
Stupidity: In "Studio Stoops," one mobster ties Larry to a bed and another mobster ties Moe to a chair. The second mobster says, "Boss, why don't you let me plug 'em?" The other replies, "It would make too much noise. Wait till we get 'em outside." If that is the plan, then why tie up Moe and Larry indoors?
The Pin-Up - S7-E17

Stupidity: Mickey, and Terry are robbing a marijuana dispensary. They subdue the armed security guard by putting him to sleep and handcuffing and duct taping his mouth with no gloves on. They are touching door handles, door frames, shiny handcuffs, and duct tape which all are excellent sources for leaving behind fingerprints. The sticky side of tape is an excellent source of leaving fingerprints. (00:24:30)
All Politics is Local - S1-E24
Stupidity: At the end of the episode, Joey and Melissa are in the kitchen, discussing Melissa's father. A small pot on the stove is very full of broccoli; almost overflowing. It makes no sense that Joey - who is a proficient cook - would be trying to prepare that much broccoli in a pot of that size.
A Frightened Hound Meets Demons Underground - S1-E14
Stupidity: The bad guy is dumb enough to stay in the basement of Captain Sally's instead of taking his loot and fleeing.
Stupidity: When an officer is speaking to who he thinks is colonel Tuttle but is really Radar with a surgical mask, he says what he needs to and is about to leave. Radar who was alone at the time and was completely in on the fact that Tuttle never existed, could have kept up the façade and let him leave, but instead chooses to reveal himself which was utterly pointless.
The Tale of the Dream Girl - S3-E10
Stupidity: A boy walking through the bowling alley stops and lets Johnny pass, even though Johnny is supposed to be a ghost no one can see.
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.
405 Method Not Allowed - S4-E5
Stupidity: Elliot and his crew are trying to take down the Dark Army and Whiterose, they are being monitored by them via surveillance vans which Elliot just burned, etc. However, with Elliot and friends trying to be secretive he somehow manages to text Phillip Price on his cell phone about Tyrell. Phones are the easiest to intercept. Whiterose doesn't trust Phillip and plans on killing Elliot once their projects transferred to Africa. (00:07:20)
Hanging with Axel: Part 2 - S3-E5
Stupidity: Hassleberry and Jesse sneak around Axel to free Syrus from the tree whilst Axel is distracted with the duel. They are trying to be discreet whilst Axel is distracted, but Hassleberry shouts "Hey, Sarge. Open up a can of Neos on this guy" to Jaden, even though Axel would definitely hear this. (00:06:38)
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 brothers are angry at Leo because they say he's responsible for them dying because he chose to save other soldiers instead of them, Leo also blames himself for the same reason and says he should have stayed and gotten them out. But in the flashback it shows Leo helping them and then running off to help other soldiers, after he runs off the brothers are killed just a few seconds later. Even if Leo had chosen to stay with the brother he couldn't have gotten them out in time, the only difference would have been Leo would have died with them, but Leo dies in the same war so he didn't live much longer. Leo's guilt and the brothers' blame don't make any sense at all.
Storm Before the Calm: Part II - S1-E38
Stupidity: Shane could have easily avoided the blast from Lothor by simply flying away to dodge it. Instead, he just hovers over him and allows his Battlizer to be destroyed.
