"It's a Wishful Life": The episode has the moral that you should do good deeds regardless of whether the person you serve expresses gratitude. Except what incited the plot wasn't simply that Timmy was annoyed from not getting any thanks for his good deeds, but that highly specific scenarios (Timmy just so happened to clean the yard on "Worst Yard Day") or arbitrary complaints (the new computer he bought AJ became obsolete mere seconds before he gave it as a present) caused the servees to deride and punish him for his actions.
The TV Movie Channel Chasers and other episodes, have the moral that Timmy's parents love him and do a lot for him, and he should show respect as a result. Yet, when his parents aren't forgetting Timmy exists or going on frivolous nights out using his college fund, they're making not-so-subtle implications that he has nothing going for him and is weighing them down or should have been a girl. Heck, these episodes seem to forget that Timmy having a Hilariously Abusive Childhood is baked into the premise of the show, as their neglect is main reason that he was assigned Cosmo and Wanda in the pilot episode.
"Fool's Day Out" tries to convey the message that pranks should always be harmless, and one should never go too far with them. The reason Timmy's revenge-pranking everyone in the first place, meanwhile, is that they sicced an angry groundhog on him and laughed as it mauled him, something the narrative treats as being perfectly okay. In fact, while Timmy and the Fool's pranks are rather mean-spirited, they never actually cause any physical harm, and the moment the Fool does tries to harm someone, it's Timmy who immediately calls off both the prank and the deal. To add insult, the episode ends with Cosmo and Wanda - the latter of whom was the Fool's main critic - pulling the angry groundhog prank on Timmy.
"The Boy Who Would Be Queen" is all about how boys and girls aren't really all that different, and that it's okay for boys to be stereotypically "girly" and vice versa. However, every gag in the show relies on the opposite assumption, such as the assertion that boys and girls speak mutually unintelligible languages (even at the end, when Timmy is giving the Aesop, Trixie needs a translator to understand what he's saying).
"Love Struck!" is trying to provide a message about the world can't function properly without love. This is executed by Timmy wishing to separate the genders, who are ultimately satisfied with this arrangement until they find some mysterious "void" in their life they can't fill. Each section of the world is also a heavily stereotyped version of itself, and when they finally meet, they go to war with each other until Cupid skewers them with arrows and forces them to fall in love. So the message is largely "guys and girls are fine without each other, until they get bored and horny." Not to mention the unpleasant undertones of implying that a world where the genders are separated is entirely loveless.
"Beach Blanket Bozos" has Timmy wish that his parents were the best surfers ever during their vacation to Hawaii. However, since they both can't be the best, Timmy's parents become locked in a never-ending surfing competition that can't be broken until they find something that's more important than surfing. That something turns out to be Timmy himself, as his parents both go to save him when he gets attacked by a sea monster. Unfortunately, this heartwarming moment is completely cheapened by the episode's opening, which shows that Timmy's parents shipped him to Hawaii in a dog crate so they could bring their surfboards on the plane with them.
The message in "Vicky Gets Fired" is supposed to be that sometimes it's important to make sacrifices to avoid putting others in harm's way. Unfortunately, the way the message is delivered makes it seem like it's trying to encourage people to stay in abusive relationships so nobody else gets hurt.
”Dream Goat” attempts to teach an Honesty Aesop when Timmy wishes for a goat named Chompy to go free, resulting in the blame being pinned on Vicky and as a result she gets hauled off to jail with Timmy living with so much guilt that he impulsively wishes for a monster that won’t go away until he tells the truth about Chompy. The problem with this moral here are the characters used for the moral to convey itself through in the episode, which are Timmy and Vicky. Here it depicts Timmy’s decision to lie about Vicky as wrong and when Timmy tells the truth, he gets grounded severely. However, the moral ends up setting a Double Standard as episodes before and after this one showed Vicky committing numerous crimes and framing Timmy for them by lying to his parents and Vicky gets away with these crimes and lies most of the time, a fact which also means viewers who regularly watch the show would probably view Vicky's treatment here as deserved payback and karmic punishment.
"Merry Wishmas":
The episode tries to present the moral "Instead of being angry about what you didn't get, you should be thankful for what you already have." However, this is thrown out the window from the very beginning because not only did Timmy not get a single toy, regardless of whether if it was on his list or not, but he was given snow shovels, rock salt, and other gifts that allowed his parents to be able to use him as their personal indentured servant while they relax on Christmas, which they don't hesitate to do. As such, Timmy's anger was justified and had nothing to do with being ungrateful.
What makes the episode even more confusing is that it's not clear on who exactly is supposed to be sympathized with. "Not on the List," in particular, goes back and forth between genuinely sympathetic and Unintentionally Unsympathetic characters; some characters' complaints seem valid (such as the little girl who wanted a cute dress, but instead got a football and a G.I. Joe Expy), while others just come off as Spoiled Brats (such as A.J. wanting a trip to the International Space Station). Santa Claus tries to claim that he was trying to teach a lesson about giving instead of receiving on Christmas... but he only admits this after having spent an entire year freeloading at Timmy's house, driving him and his parents nuts, and blatantly dodging Timmy's question about why he didn't just give Timmy a sled in the first place. Santa’s attempt to teach Timmy and everyone else a lesson about giving also does not apply on Timmy’s end as Timmy was being kind and giving to others when he made his wish to give everyone wish coupons so they could get the stuff they wanted, which was supposed to go well until Vicky ruined everything with her wish to receive a million wishes. Also, thanks to the point listed above, Timmy learning this lesson doesn't work because, once again, this was an episode where Timmy was actually unselfish and well-meaning.
"Beddy Bye" tries to teach a Be Careful What You Wish For message... the one time Timmy didn't get what he wished for. His actual wish was that everybody didn’t have to sleep. What happened was that people still needed to sleep, they just weren't able to — which is a blatant misinterpretation of what he actually wished for.
"Emotion Commotion!": Wanda claims that the moral of the story is that "it's better to live with your emotions than without them". However, Timmy was actually doing perfectly fine without his emotions. People were either too amazed by, or too afraid of, a Timmy who didn't show any emotions. And because he was more rational and logical, and showed no fear, he could pull off death-defying stunts, with none of the negative consequences you'd expect from such a scenario. Timmy does request his emotions back after he realizes that he can't actually enjoy his newfound respect without emotions, but this too is shown to be simply the result of him reasoning through it. In fact, things only started to go wrong after Cosmo gave him back his emotions, in the middle of rescuing his friends no less, something that Timmy called attention to and didn't forgive him over. There's potentially a moral here about emotions being best used in the proper context, but it's entirely botched by its delivery.
The episode “Dumbbell Curve” teaches the moral that in order to get good grades and be successful in life, kids need to put in their best effort in their homework, studying, and tests. However, the moral fails to adhere to the episode as the episode’s conflict is not caused by Timmy’s effort or lack thereof in his studies but by the implementation of a new grading system by Crocker at the last minute. Before this, Timmy do put in the effort and gets a high grade for once (a 92/100), but since he got the lowest score in his class (as everyone else got a 93 and above), he gets flunked in his assignment anyway.
The Made-For-TV Live-Action MovieA Fairly Odd Movie: Grow Up, Timmy Turner! sees Timmy, now 23 years old pretending to still be technically a child to be able to keep his fairly godparents he has to abandon when he's grown up. The movie has Timmy to realize he finally has to act his age and has to have let his childhood - including his godparents - go. However, while he seemingly learns that lesson, in the end he is able to still keep his godparents as part of the fairy world thanking him for saving them multiple times. While this is true, it goes against the point of having to let go.
