The Fairly OddParents aired on Nickelodeon for over 16 years, amassing a large and loyal fan base. Naturally, this means there are plenty of weird Fairly OddParents fan theories floating around the internet - some more believable than others, and some designed to hit you right in the childhood. Created by Butch Hartman, the show centered around Timmy Turner, a kid with loving but neglectful parents, a terrible babysitter, and an acutely paranoid school teacher. Timmy's life turns around, however, when he gets fairy godparents in the form of Cosmo and Wanda.
Often disguised as pet goldfish, the goofy married couple stays by Timmy's side to grant his every wish. However, these wishes rarely work out as expected, either because of Timmy's lack of forethought or Cosmo and Wanda's incompetence. The show initially aired until 2006, but it returned in 2008 and carried on until Hartman's departure from Nickelodeon in February 2018, suspending production indefinitely. Its success even spawned three live-action TV movie adaptations starring Drake Bell as a 23-year-old Timmy, still accompanied by Cosmo and Wanda in his adult life. Most fans would agree, though, that nothing compares to the original cartoon.
The Dinklebergs are the Turner family's irritating, childless neighbors. Redditor /u/kicka**etter thinks the couple's name might give insight into what they represent:
I believe that the Dinklebergs are a play on the term DINK, or "Double Income, No Kids." It's mentioned many times that they have no children, a lot of money, plenty of free time, and have had a relatively successful life while Dad came up short, got a mediocre job... and had Timmy. He's not unhappy that he has Timmy, but still resents the Dinklebergs for all of the reasons any parents might have towards couples who don't have children.
The reality of Timmy's life is a bit bleak on close examination, hinted at by the line, "Doom and gloom up in his room," in the show's opening theme song. But an anonymous theory on Imgur reckons his life is even worse than we think:
The Fairly OddParents is about a kid playing pretend with his fish. His godparents [perished] in a car crash when he was younger; since they were the only adults who ever understood him, he finds comfort in imagining that they are there to watch over him since his parents obviously don't care. His babysitter slaps him around... Mr. Crocker has made [inappropriate] advances on young Timmy for years, hence the delusion that he is desperate to steal Timmy's "fairies," which represent his innocence, joy, hope, and good wishes for the future.
The anonymous user concludes that "the granted wishes are all in [Timmy's] imagination, hence why they never have any lasting consequences."
John Negroni, the author of The Pixar Theory, spent a lot of time trying to figure out what the central message of The Fairly OddParents was. According to Negroni, the show's main theme is, "You don’t really grow up until you figure out how to properly deal with your problems." He continued his theory:
One thing that bothers me about TFO (and it probably bothers you, too) is that Timmy Turner learns the same lesson every single week. This lesson is that you can’t just wish your problems away. Every time you do, you end up creating more problems. And even in a world where you get everything you want, there are still rules, terms, and conditions that will hold you back.
Which brings me to the true purpose of The Fairly OddParents. It’s not simply to give us a show where we can laugh at the misfortunes of a 10-year-old boy who has the world at his fingertips. It’s to show us that the fairy godparents aren’t really there to just give Timmy whatever he wants. Instead, the whole point of giving Timmy fairy godparents is to teach him that he doesn't need them. In fact, the very first episode of the main show is about Timmy wishing that he was grown up, instead of just... well, growing up the normal way.
Crocker's fairy paranoia is one of the show's best running gags. The teacher is also one of Timmy, Wanda, and Cosmo's main antagonists. But Redditor /u/Mutant_Llama1 think it's hardly coincidental that a fairy-owning kid would be thrust right under the demented teacher's nose:
It's revealed in one episode that Crocker's [craziness] over fairies is what's powering the Big Wand in Fairy World. If Crocker became sane, it would lead to a power shortage. This may explain why Vicky is kept around despite her evilness. Jorgen uses magic to manipulate people's minds to let Vicky keep making Timmy miserable, so that Timmy can be given [Wanda and Cosmo]. Timmy having fairies is what makes Crocker freak out. Its all a big conspiracy to maintain the power supply.
