History Fridge / CaptainUnderpantsTheFirstEpicMovie

* According to Professor Poopypants, he's tried to remove the Haha-Guffaw-Chucklomatus only to find out that a person can't survive without it. He probably discovered that because he was doing some illegal mad scientist experimentation on unwilling test subjects.

* Considering the massive amount of property damage done to the school after the disaster that was the carnival, Krupp separating George and Harold was ''letting them off easy''. As far as he knew, they were completely at fault for this. He could very easily have had them ''arrested'' if he wanted!

* As a kid, this movie is hilarious. As an adult, the idea that you have an uncontrollable split personality controlled by two ten year olds and you have no idea how it's triggered or that it even exists, all you know is that you're having blackouts and then [[WhatDidIDoLastNight ending up in really crazy situations half-naked, soaking wet and with possible unexplained injuries]]...to be fair, it could be a lot worse if George and Harold weren't decent kids who don't want to see Krupp get hurt despite what he's done to them, but if they weren't, it could be a very bad situation.

*** This theory also works for the books: In the fifth book, Mr. Krupp read a comic George and Harold wrote where that Captain Underpants was temporary defeated by [[WeaksauceWeakness spray starch]] and when he was later sprayed with spray starch after turning into Captain Underpants, he thought that he lost his powers [[spoiler: until George and Harold wrote a comic book that said that he was "immune" to spray starch]].

* If we take it that Captain Underpants is in part an unconscious reflection of Krupp's good side that's been buried under years of bitter loneliness, then it makes total sense that he found their comics ActuallyPrettyFunny in the end. He might have always been able to enjoy that kind of stuff but just was never in the mood to give it a chance before.

* When Professor Poopypants is checking to see if Melvin has a sense of humor, he shows him a series of humorous clips which he (in spite of his goals) finds funny. One clip he says is "really good" shows a man about to slip on a banana peel but [[UpToEleven is hit with a safe instead]]. Naturally you'd assume that this can be chalked up to classic schadenfreude, but on further analysis, that clip showed a typical comedic scenario (slipping on a banana peel) and ''subverted'' it (being hit with a safe instead.) In other words, it's an anti-joke. A pretty fitting thing for the humor-hating Poopypants to enjoy.

* Wonder if those two girls Professor Poopypants [[DisproportionateRetribution put in a cage for laughing]] won't be [[AdultFear scarred by the punishment]]. What's more, does that cage come with a key?
* Even before [[spoiler: Professor Poopypants' plan]], this school was essentially ''[[{{Brainwashed}} brainwashing]]'' kids to be unimaginative and miserable, and the parents (likely) ''[[AdultFear had no idea!]]''

* [[spoiler: Why was George able to resist Poopypants' laughter killing beam longer than George? Simple: while it takes a lot of creativity to create a good piece of art, it takes arguably MORE creativity to create a good STORY. George was simply more creative.]]
