History TearJerker / PhineasAndFerb

--->'''Phineas:''' Hey, this is. We would never want to hurt each other."

* The sad look on Perry as he gets mindwiped and how he uses all of his remaining will to write “I fight evil“ gets me every time.

*** On another related note, which isn't so much a tear jerker but a sweet sort of thing, is when Candace is in the boys' kiddie ride in one of the episodes. She eventually falls down a canyon after the engine sputters out... then she doesn't have another quarter to put in to power it up. She screams for Phineas to help her but who's the one who realizes shes falling and pretends to be a dancing little statue thing all just to get a quarter to save her? Ferb.

* When Perry is hanging up his hat, it looks as if Carl is crying. The worst part? Hes not breaking down crying, he's just crying, as if he's not trying to draw any attention to it.

** Even worse: when the gang gets stranded on the island, Isabella ''cries'' while she admits her feelings to Ferb.

* Man, Dr. Doofenshmirtz had it ''rough'' as a kid. Sure, it's mostly PlayedForLaughs and he's not exactly the nicest guy but...Jesus! Having to set up your own "Surprise birthday party", and spend most of your childhood as a Gnome?! Not to mention the fact that his parents never showed up for his own birth! It's kind of hard not to feel for the guy. His daughter Vanessa even lampshades this, pointing out that Doof isn't actually EVIL, he just lashes out through what he thinks evil is, which is why so many of his plans amounted to PokeThePoodle even if they had succeeded. He has no real malevolence, in contrast to Alternate Doof from the other dimension, he's just angry because of his lonely and neglected childhood [[spoiler: which sets up his HeelFaceTurn at the end of the series]]. Ultimately, he's a brilliant man who can work for the betterment of all mankind if he could only see past his pain.

-->'''Candace:''' I'm a freak. ''(starts to cry)'' I'll never be a flawless girl! ''([[GiantsDropletHumansShower a single, giant tear drops from her face and falls to the ground as Ferb grabs an umbrella and puts it over him and Phineas to cover themselves]])'' There's only one place where a girl like me will fit in: the oddball show! It was nice knowing you boys, tell Mom and Dad I love them. From now on I'll be living amongst the carnies! ''(starts crying and runs off as Phineas and Ferb watch)''

* "[[https://www.youtube.com/watch?v=nvhKQr3RxNM Couldn't Kick My Way Right Into Her Heart]]" is partly as comically ridiculous as any other Doofenshmirtz backstory, but at the same time very sad.

-->'''Doofenshmirtz:''' This is why I'd rather not make friends. They find someone else, and "Bam!" You're alone.

-->'''Stacy''': Wait a minute! It says right here in your silly little pamphlet that if your host family finds out about your agent status, then anyone who's seen you has to have their memory erased, or you'll get relocated. Perry, I'm not part of your host family! I know, I know, it's a technicality. Look, I don't want Candace and the boys to lose you, but I also do not want my mind erased. I'm on the last ten minutes of that "Grievance" movie, and I don't want to have to watch that whole scary mess again. So, uh, can we just keep this a secret?
-->''(Perry grins and tips his hat to Stacy)''

* Watching Phineas give up hope on the island. This kid, this ever-optimistic kid who's never given up on anything before, just completely fall apart, realizing he ''doesn't know what to do''.
** "We could...we can...we can...we...we...we ''can't''..." Hearing one of the biggest and most lovable optimists in modern television say those two simple words is nothing short of '''gut-wrenching'''. It’s also worth mentioning how heartbreaking Creator/VincentMartella’s [[SugarWiki/HeReallyCanAct acting]] is in this scene.
** As well as the scene just before it. Isabella ''never'' cries, but she did then. It all soon gets better when Isabella realizes Phineas' sadness and encourages him not to give up.
* [[https://www.youtube.com/watch?v=95uNiwotdaI&feature=related "The City of Love"]]. It's the culmination of how many seasons of Isabella's frustrations and Phineas' [[ChasteHero Freaking.]] {{Oblivious|ToLove}}ness. Her plaintive little voice, and the fact that he's still oblivious as she sings this ''right in front of him'' are just sadness on overdrive.

--> "She went off with someone else."

* Phineas' lack of tolerance for Candace's mistakes is really saddening (though it will probably be for different reasons for different people). She tries to apologise to him several times, but he is too frustrated at her to accept any apologies.
** In particular, the part where Candace tries to talk to Ferb about it only for Phineas to divert the attention of both of them is pretty sad.

* The boys have both been heartlessly brainwashed, removing their creativity and imaginations (which may, in ''itself'', be an example). They and Candace have been cornered by the [[BigBad Smile-Away sergeant]], so their only means of escape are by building a bridge. Candace begs them to come to their senses, telling them that, despite the way she's treated them all summer, their creativity isn't bad but, in fact, the ''best thing about them'' and she's [[SugarWiki/HeartwarmingMoments always secretly been proud to be their big sister]]. She then starts to sob and cries out "[[MyGodWhatHaveIDone What have I done? WHAT HAVE I DONE?!]]". Slowly, Phineas blinks, then reaches forward to take the wrench from her hand. She looks up at him with tears running down her face. Phineas smiles and she smiles back. Granted this ''was'' all a dream [[spoiler:within a dream]], but it still shows she loves them. It’s also hard not to give Creator/AshleyTisdale credit for her [[SugarWiki/SheReallyCanAct painful performance]] in this scene.
