History TearJerker / TheEpicTalesOfCaptainUnderpants

* The animals’ whole reason for becoming hostile in “The Angry Abnormal Atrocities of the Aggressive Animals.” How would you like it if you were forced to eat garbage while your boss eats fresh food?

* "The Flustering Mindless Wow of the Flushable Memory Wipes", where we learn that Mr. Murdsly's whole reason for brainwashing the kids is to get revenge on the people who wronged him as a kid. The humiliation stuck with him throughout his whole childhood and it embittered him in his adulthood, especially since the cruel nickname they gave him, "Ted Turdsly" is still being used by the kids to this very day, which is TruthInTelevision. George and Harold actually sympathize with Mursdly and decide to end the cycle.

'''Harold:''' Yeah... you. So, we’re giving it back to you instead. We were wrong, and we accept our fate. And... sorry.]]\\

-->'''Mr. Krupp:''' What...? My rule book? How did you get this?]]\\

* The moment in “[[HalloweenSpecial The Spooky Tale of Captain Underpants: Hack-A-Ween]]”, when George and Harold realize why Melvin hates Halloween and wanted it cancelled; [[spoiler:because they never invited him to go Trick-or-Treating with them.]]

* Even with how mean [[ChildHater Mr. Krupp]] is, you can't help but feel sorry for him when he sees [[GratuitousFrench Ms. Yewh]] [[DidNotGetTheGirl hit it off with none other than]] [[spoiler:''[[AlmightyJanitor Mr. Ree]]'']] in "The Terrifying Perilous Misfortune of the T.P. Mummy."

* In the Season 1 finale, after [[spoiler:finally getting Mr. Krupp’s rule book so they can give it to the Superintendent and have him fired before he can expel them, they see Mr. Krupp look fondly at a framed picture of the day he first started work as Principal, which makes them realize that they can’t go through with it]].
-->'''Harold:''' [[spoiler:If we get expelled, we’ve still got each other. But... ''being Principal is all Mr. Krupp’s got''. We gotta give the book back to Krupp.]]\\
'''George:''' [[spoiler:That’ll be Visit 500.]]\\
'''Harold:''' [[spoiler:Yep...]]
** Then comes the scene right afterwards [[spoiler:where they give Krupp’s rule book back to him]].
-->'''Mr. Krupp:''' [[spoiler:What...? My rule book? How did you get this?]]\\
'''Harold:''' [[spoiler:It doesn’t matter.]]\\
'''George:''' [[spoiler:We were going to give it to Dr. Vil Endenemys, to get you fired before you could expel us.]]\\
'''Harold:''' [[spoiler:But that felt like a really mean thing to do. And we thought, we’re not like that! We’re not like...]]\\
'''Mr. Krupp:''' [[spoiler:(''looks like he’s about to start crying'') ...''M-Me?'']]\\

'''George:''' [[spoiler:We apologize.]]
* In the Season 2 finale, [[spoiler:Melvin-Borg explains that his nanobots, which took over Captain Underpants’ body, are slowly taking over his brain, and once they do, they will effectively destroy who he is. Upon this revelation, and realizing that if they don’t act fast, Captain will be gone forever, George and Harold actually start ''crying''.[[note]]This is a FAR cry from [[AngstWhatAngst how they reacted to his “death” at the end of the book series]].[[/note]]]]
* [[{{Cliffhanger}} The ending of the Season 2 finale]]. [[spoiler:After spending the entire season trying to keep their grades up so they can go to summer camp, George and Harold are all set to go... only to discover that they’re going to ''two different camps''. The sad piano music playing over the end credits doesn’t help.]]
** [[spoiler: Actively made ''worse'' in a Season 3 trailer that revealed they've ended up at the same camp anyway, to their delight, but then Krupp appears, reveals it was all his doing and that he intends to keep them separated for the entire summer. The montage of George and Harold trying and failing to interact through the massive fence Krupp somehow got put up is heartbreaking.]]
