Yes, even a show as silly as this can seriously tug at the heartstrings sometimes.
- In The Vexing Villainy of the Vile Vimpire, some of the things Captain Underpants says after being bitten by the titular villain are just downright heartbreaking, especially if you take into account that these are most likely Krupps memories and subconscious feelings.Captain Underpants: Ive never felt truly loved!
George: We cant win!
- Also, from the same episode, this exchange between George and Harold after theyre bitten.note
Harold: We won when we met. And since were never gonna be happy again... I want you to know that was the happiest day of my life!
George: Not as happy as every day I got to spend with you!
- Even with how mean Mr. Krupp is, you can't help but feel sorry for him when he sees Ms. Yewh hit it off with none other than Mr. Ree in "The Terrifying Perilous Misfortune of the T.P. Mummy."Mr. Krupp: I ate a snail for her...
- "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 Truth in Television. George and Harold actually sympathize with Mursdly and decide to end the cycle.
- The flashback to Krupps childhood in episode 11. I mean, getting publicly humiliated by not only his classmates, but his own mother? You just wanna give the poor little guy a hug...
- In the Season 1 finale, after finally getting Mr. Krupps 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 cant go through with it.Harold: If we get expelled, weve still got each other. But... being Principal is all Mr. Krupps got. We gotta give the book back to Krupp.
George: Thatll be Visit 500.
Mr. Krupp: What...? My rule book? How did you get this?
- Then comes the scene right afterwards where they give Krupps rule book back to him.
Harold: It doesnt matter.
George: We were going to give it to Dr. Vil Endenemys, to get you fired before you could expel us.
Harold: But that felt like a really mean thing to do. And we thought, were not like that! Were not like...
Mr. Krupp: (looks like hes about to start crying) ...M-Me?
Harold: Yeah... you. So, were giving it back to you instead. We were wrong, and we accept our fate. And... sorry.
George: We apologize.
- In the Season 2 finale, 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 dont act fast, Captain will be gone forever, George and Harold actually start crying.note
- The ending of the Season 2 finale. 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 theyre going to two different camps. The sad piano music playing over the end credits doesnt help.
- 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.
- 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?
