History NightmareFuel / CaptainUnderpantsTheFirstEpicMovie

* Mr. Krupp's [[SlasherSmile Slasher Smiles]] can be a bit unnerving. Just look at the trope page image! George and Harold got literal chills when they saw that one.

----> '''Harold''': George! I can't...smile anymore...!

---> '''Harold''': George! I can't...smile anymore...!

* We get another moment during the Carnival scene thanks to some good ol' MoodWhiplash. Specifically, the moment that it starts raining. Every other time in the movie, Krupp’s anger is usually over the top and PlayedForLaughs... but ''not this time''. Here, he is furious to the point of TranquilFury, and it is genuinely '''terrifying'''. Also, the boys can't even switch him back to Captain Underpants this time.

Yes, even a movie about a fat bald man who thinks he's a superhero can be [[NightmareFuel utterly terrifying]] at times...

*** The aforementioned line implies that he ''is'' trying to smile, but with the ray's effects being turned up at the third notch, it's forcing him to frown.

** It's worth noting that earlier, Harold mentioned that if Poopypants destroyed his and George's sense of humour, it would result in a ''DeathOfPersonality''.

*** And if you look closely at when both boys succumb to the effects, ''their skin appears to turn blue''[[note]] though it's kind of hard to tell because of the lighting or the ray in general (though it looks more evident with Harold since he succumbed when the ray was bright red) [[/note]], unlike the other kids.

*** What immediately follows is just as bad. George (and by extension the audience) sees him and tries to get him to snap out of it, but it's no use. Then Harold dips his head and passes out before raising it and revealing his GlowingEyes. As we see him give up, it seems like he's not only looking at George but ''[[TheFourthWallWillNotProtectYou audience as well.]]'' [[note]] And again, the same thing with George. [[/note]] [[TheFourthWallWillNotProtectYou He even stares at the screen with a blank expression after losing his ability to laugh]], which is pretty unsettling to look at.

*** Both boys have been [[HeroicWillpower resisting the effects]] until the mad scientist turns up the notch to the point where the ray is glowing red. While George is still resisting, albeit having an [[TheUnSmile Unsmile]] on his face, Harold...[[{{Understatement}} not so much.]] How do we know effects are starting to overpower him? We see his eyes visibly droop. And there's this line:
