History WhatAnIdiot / PhineasAndFerb

** A good example of this is in "Phineas and Ferb-Busters!". Candace forms a team with Stacy and Jenny known as the Phineas and Ferb-busters, which includes communication headsets so they can signal each other. Around the same time, Phineas and Ferb build a set of giant tops for them, Isabella, and Baljeet to ride in, inspired by a board game they were playing with them and Buford. These tops are powered by a power source that radiates energy across the yard. As Candace, Stacy, and Jenny spy on Phineas and Ferb, Buford turns up the power source, causing the tops to spin out of control, and also overloading and destroying Stacy and Jenny's headsets, so they're unable to signal Candace. When Linda arrives home, she hears noise in the backyard and decides to go there to see if Phineas and Ferb are up to something wild and dangerous, like Candace said they would be, but Candace cannot let her in yet until she gets the signal "The pea is in the pod" from Jenny and Stacy, who are somehow not responding.\\
'''You'd Expect''': Candace would let Linda investigate anyway, so that she can see Phineas and Ferb riding the tops and punish them for it, thus finally letting Candace accomplish her goal of busting Phineas and Ferb.\\
'''You'd ALSO Expect''': Candace to check the backyard to see if Stacy and Jenny are around.\\
'''Instead''': Candace, obsessed with having her new team's work go according to plan, refuses to let Linda in the backyard until she gets the signal from Stacy and Jenny. Because the headsets are destroyed, they can't signal her.\\
'''The Result''': When Phineas, Ferb, Isabella, and Baljeet stop riding their tops, the tops fly away. Around the same time, Perry shuts off the power source. Thus, when Linda finally does get to the backyard, she finds Phineas and Ferb playing the top-themed board game with Isabella, Baljeet, and Buford. When Stacy and Jenny tell her what really happened, she doesn't believe them, as per the norm with Candace.

* "Lost in Danville":
** Candace tells the boys that she wants a day off from their inventions so that she can relax and listen to an album. It turns out they aren't responsible for this day's shenanigans -- a strange capsule with an old man inside it. The capsule is revealed to contain a black hole, which nearly sucks in the boys and their friends. They call to Candace for help when Isabella remembers the inventions always disappears when Candace tries to show them to her mom.\\
'''You'd Expect''': Candace on seeing that her brothers are in danger would do her usual LetsGetDangerous mode or ask Phineas how she can stop the black hole.\\
'''Instead''': She goes for her mom, completely disregarding that Phineas and Ferb need her help.\\
'''Fortunately''': Just before the black hole can kill the gang, Professor Mystery's -inator destroys it and saves everyone.
** Meanwhile, Doofenshmirtz has been kidnapped by Professor Mystery, who accuses him of stealing Peter the Panda as a nemesis. Professor Mystery refuses to explain what the -inator aimed at a BoundAndGagged Doofenshmirtz is.\\
'''You'd Expect''': Doofenshmirtz would realize he's dealing with a murderous [[ClingyJealousGirl Clingy Jealous Guy]] and tell Professor Mystery that he hasn't seen Peter in a while -- not since the latest Meep invasion-- and that they aren't a thing.\\
'''Or''': Stall for time and keep the other villain placated. A dangerous weapon aimed at your head is never a laughing matter.\\
'''Instead''': Doofenshmirtz keeps criticizing how Professor Mystery is LostInCharacter, invoking how a standard villain and hero relationship needs communication, from explaining backstories to monologuing about -inators. He then does a song and dance number, complete with chorus girls. And he doesn't ask the chorus girls to free him after the number.\\
'''The Result''': Professor Mystery is not placated at all and getting more irked by the minute. He nearly destroys Doofenshmirtz with the Unexistenator, if not for Peter the Panda showing up to beat the crap out of Professor Mystery and Perry redirecting the Inator's beam.

* Well, alright, but there's still Isabella's crush on Phineas, and how obvious she makes it.\\
'''You'd Expect:''' Phineas eventually put two and two together.\\
'''Or:''' Isabella would straight-up admit her love to Phineas.\\
'''Instead:''' [[ObliviousToLove He's just completely oblivious to it, which sadly continues throughout the series.]] She's also too afraid to tell him herself.

* In "Primal Perry", the boys' Infinite Probability Generator causes Baljeet to split into multiple copies of himself whenever he is indecisive. Candace tries, again, to show this to Linda in the kitchen, who is busy with early spring cleaning. Naturally, she doesn't notice because her back is turned.\\
'''You'd expect:''' Candace to just pull Linda outside to show her the generator, which is just out the door.\\
'''Instead:''' She just keeps shouting, "Mom!", but she ignores her.

* In the pilot episode, "Rollercoaster", Ferb puts up a poster advertising the Coolest Coaster Ever. Later, Candace sees it at the supermarket.\\

'''You'd Expect''': Candace too, keeping in mind that her brothers' inventions normally work, not to say anything bad about the animals, some of which are clearly vicious (there are a bear and lion in the backyard, for example).\\

'''Or''': Lie to Perry about the self-destruct button 's location and hopefully get him to press the fire button instead.\\

'''The Result''': Not only does this fix Candace's hair, it also causes hair to grow all over her body and be mistaken for the tangerine orangutan.

'''What's Worse?:''' Is after thinking his plan worked, he decides to destroy the helmet without a second thought for some reason. You'd think he'd want to keep an invention like that around in case of a similar ordeal like this happening to him again in the future.
