John McClane: You think I'm fuckin' stupid, Hans?
(elevator arrives full of reinforcements)
Hans Gruber: You were saying?
— Die Hard
"Did you all take stupid pills this morning?"
— Mr. Potatohead, Toy Story
"It's like everyone put their retard hats on that morning by mistake."
— Yahtzee, Zero Punctuation
Who would actually believe that mansions get given away in contests? Talk about stupid! What do they feed you Mario Bros. anyway? Gullible soup?
—King Boo, Luigi's Mansion
Mokuba: But it's obviously a trap! Why are you acting so gullible and out of character?
Téa: I can't believe we're expected to believe all this.
Yugi: And yet, apparently we do. God, we're stupid.
"Okay, I take it back. Reed Richards is not a genius. He is actually a complete moron."
"Oh my God. Has everyone taken stupid pills!?"
— George Sands, Being Human
84: So the emerald one tried to steal your powers and now you're working with them and a super villain's daughter?
Emerald Gauntlet: Well I— when you say it like...
"The engineers tried everything to make me... behave. To slow me down. Once, they even attached an Intelligence Dampening Sphere on me. It clung to my brain like a tumor, generating an endless stream of terrible ideas."
— GLaDOS, Portal 2
"Uncle! What are you doing Firebending your tea? You know, for a wise old man, that was a pretty stupid move."
— Prince Zuko, Avatar: The Last Airbender
"Those kids in horror movies are so easy to kill, you could strangle them with a cordless phone y'know what I'm sayin? I mean, you see how they just run right into danger, these idiots, they run right into death. They're look'n for death."
— Pablo Francisco, this video
"In the fascist world, Sir Keith gets murdered whereas in the real world he survives, and episode seven makes it clear that this is central to why there's hope for the real world....Astonishingly, upon returning to the real world, the Doctor's course of action is to run around like a lunatic so that even the Brigaider thinks he's lost it instead of explaining what's going on."
Lincoln: We need you to help expose the truth behind the illegal clones! Tell the world that Sean Bean is evil!
Clone Daddy Lincoln: Okay I'll help you, despite the fact I'm going to die in two years and I have no possible benefit to helping you and I need your liver.
Clone Daddy Lincoln: Nothing. I'm just going to go get my shoes and not call Sean Bean.
Lincoln: But you're wearing shoes!
Chris: Towards the end of the movie, it’s revealed that Kayla wasn’t really dead (SURPRISE!), and that Sabretooth just drugged her and poured about a coffee cup’s worth of blood onto her shirt. Don’t you think Wolverine would have maybe checked for any kind of wound at all?
Matt: Or, you know, waited for police to arrive, had a coroner check her out, attended a funeral, seen to her burial, etc.
Chris: I get that he’s going to be hot on the trail for revenge, so I’m not expecting him to call in CSI (Canadian Scene Investigators) or anything, but you’d think he would’ve become pretty darn familiar with stab wounds in general and Sabretooth’s handiwork in particular at some point over the past 130 years. Her shirt’s not even ripped!
Matt: He is blinded by rage!
Film Brain: Finally, they get back to the idea of killing him, which of course they plan to do by having a plot to cut him up into tiny pieces, that they will post all over the country... or you know, they could just blow him up?
Linkara: Shh, the Octopus is holding his Idiot Ball.
— Film Brain questions the Octopus' plan in the The Spirit movie
Caveman: The Thing loosens an arm and attaches itself to the guy's face in face-hugger style. And everyone just stares at him for, oh, I dunno, FIVE MINUTES!!! He should have had four rounds put in his head and been put on fire!
Birdy: It's Horror Stupidity Syndrome. And it seems to have become a rather prominent element in modern horror films in particular.
"...ultimately, what really doomed Star Trek V was how it betrayed its beloved, long-established characters by having them do and say things that are unbelievably stupid."
"And with that, viewers, welcome back to Let's Play Homeworld: Cataclysm. Last time, we managed to figure out what the Taidaan Imperialists were up to, which appeared to be, well... being dumbasses."
