The Dumbest/Worst Phineas and Ferb Theories

This is a list of the dumbest and worst Phineas and Ferb theories that are actually being believed. Throughout this list, I am going to present evidence for why I think these theories are false, conjectural, or just blatantly awful.

Keep in mind, this list is my opinion. You may present any counter-argument that you may have, but don't try to fight with me if you think I'm way off. Do feel free to add comments and other ridiculous theories to this list.
The Top Ten
1 Candace, suffering from schizophrenia, dies. Then Linda reads her diary and asks Walt Disney to create a program in memory of her.

It's set in a fictional universe wherein the laws of physics don't apply. So seeing things that don't exist in real life are in no way indicative of schizophrenia. Also, Candace would have to have hallucinated Doofenshmirtz's inventions (at least until Season 4) and battles with Perry which she doesn't know about. Phineas and Ferb were on several occasions engage in their projects without Candace even knowing about them. And in-universe the Zebra turns out to be real. She's not schizophrenic

I have no disrespect against those who have actually schizophrenia in real life, but this theory is awful. Candace is not imagining what the boys are doing; just because Linda never sees what Phineas and Ferb do doesn't mean that other people can't.

Dan Povenmire even disproves this theory saying, and I quote, "What would that have been like?"
"'Mr. Disney, my daughter died tragically, could you make a funny cartoon from the schizophrenic ramblings in her diary?'"
"'Well you are in luck, ma'am, because all of our living non-schizophrenic writers are completely out of ideas!'"

2 Phineas got bullied a lot in school and killed, so Candace, unable to handle his death, built an imaginary world where he still exists.

This is basically the same as the Candace's diary theory above with Phineas being the dead one instead of Candace. Even though in the episode Act Your Age, Candace never once interacts with Phineas, the protagonist of that episode. And Phineas has a cameo in the episode Doof 101, Candace doesn't. For this one to work all of the characters aside from Candace who regularly interact with Phineas would also have to be dead. (Also, it's worth noting that within Danville, Phineas is actually quite popular with and well-liked by his peers rather than being a social outcast like this one implies.)

First of all, it's pretty obvious that nobody would bully Phineas, except for Buford if they weren't friends. In fact, it can be inferred that most people admire and look up to Phineas for his accomplishments and ability to make fun stuff for everyone (with the help of Ferb!).
Second, Candace's grief would likely be overshadowed by some other mental anxieties that she has, or the fact that she no longer has to, for whatever reason, try to bust Phineas for doing what Ferb and he do every day.

3 Phineas and Ferb are a figment of Candace's imagination.

Obviously not, otherwise Candace would also have to imagine Doofenshmirtz building the inators which destroy Phineas and Ferb's inventions. Considering she canonically wants to bust Phineas and Ferb so badly, that seems counterproductive.

They just ripped off the Rugrats theory.

4 Ferb has crippling mental issues.

No, he doesn't. He just isn't very talkative.

5 Dr. Doofenshmirtz is Candace's psychologist.

Of all people, how would Doofenshmirtz be able to help Candace with her mental problems, which might I add, we don;t even know if Candace even HAS confirmed mental problems. One way or another, Doofenshmirtz would not be able to help her at all, the most obvious reason for this is that he had an atrocious childhood, so he'd be trying to make Candace "evil" or something.

This is basically just trying to integrate Doofenshmirtz into the Candace is hallucinating theory and it doesn't work since before the first movie and Season 4 she isn't aware of Doofenshmirtz's existence and even after that doesn't find about his evil plans and schemes. It doesn't work.

6 Doofenshmirtz is Phineas from the future.

He has an elaborate and well-established backstory which doesn't fit into that at all. (Also, per Milo Murphy's Law, his persona from the future is Professor Time not Phineas). And there would be some horrific implications to this given Doofenshmirtz once dated Linda.

So Phineas can just magically warp to Drusselstein? I sincerely doubt it.
Phineas has no confirmed Germanic roots, a positive childhood, and his head is structurally different from Doofenshmirtz's despite being the same basic shape.
And don't worry about Agent P not knowing who Phineashmirtz really is, going back in time to clean up his messes as a kid already completely destroys the space-time continuum.

7 Pinhead Pierre is Phineas's father.

Obviously, Pinhead Pierre is a TV show, just like the group's "Team Improbable" show. They're obviously not real, it's just the magic of entertainment, kind of like special effects for a movie.

This one is so stupid that it's hilarious.

8 Doofenshmirtz is Phineas's father
9 Candace is the true villain.

No. She isn't. In Phineas and Ferb get Busted, she goes to extremes to rescue Phineas and Ferb from the military school. In Traffic Cam Caper, she sacrifices her chance at busting her brothers to save Phineas's life. In Lake Nose Monster, she lets the people think she's deluded and psychotic to protect the Lake Nose Monster. In Gaming the System, she fights tooth and nail against a digitized version of Buford to protect Phineas and Ferb from him. In Chronicles of Meep, she goes headlong into space to rescue Phineas and Ferb from aliens. And she sacrifices her chance at busting them to save them in Meepless in Seattle. She destroys her DVD so as not to bust Phineas on his birthday in the Phineas birthday episode and in Agent Doof she actively seeks to keep baby Phineas and Ferb from endangering themselves. In the first movie she explicitly says her goal is to protect her brothers and ends up deliberately weaponizing her inability to bust them to save the day. And she does everything ...more

Although I will say that she doesn't know when it would actually be necessary to bust her brothers as opposed to when she doesn't really need to, I feel like she does what she does more so to look after her brothers, because she cares a lot for them. Despite the fact that her usual rinsed-and-repeated behavior says otherwise, there are also plenty of times that show that Candace is truly caring towards Phineas and Ferb.

10 Perry the Platypus and Agent P are two different entities.

The VERY FIRST episode has Major Monogram telling Agent P to retain a cover identity as a mindless domestic pet.
In the Phineas and Ferb movie "Across the 2nd Dimension" Major Monogram reveals why that rule is in place; it wouldn't be safe for Phineas and Ferb to know Agent P's true identity. Earlier in the movie, you can also clearly see that the pet shop that Perry came from is run by O.W.C.A., which doubly reinforces the fact that Perry and Agent P are, in fact, the same platypus.

The Contenders
11 The mom knew it all

Obviously not, if she could never see what happened. If she knew, she would either have to be detained or the show would have been over a LOT sooner.

12 Perry the Platypus is Candace and Phineas's father

He's a platypus. They're humans.

13 Darth Vader is Phineas and Candace’s father
14 Doofenshmirtz works for O.W.C.A.

There are two instances where Doofenshmirtz does actually work for the O.W.C.A.. The first time Doof lost his confidence in his evil abilities. The second time, in a spin-off series that never launched, he has actually given up evil.

15 Norm the Robot is Phineas’s father
16 Linda was married to Doofenshmirtz

It was denied by the creator.

17 Charlene Doofenshmirtz is Phineas and Candace’s mother and lives a double life
18 Charlene Doofenshmirtz is Ferb’s mother
19 Ferb isn’t English but French

There is at least one reference in every episode that Ferb is English, not French. (Try to see if you can find them all!)

20 Phineas is Vanessa’s brother
21 Thaddeus, Thor, and Mandy are the cousins of the Flynn-Fletchers
22 Buford hates Baljeet

This is not dumb or good he's a bully but they sometimes have fun together

23 Heinz Doofenshmirtz is Ferb’s mother
24 Candace created Phineas and Ferb
25 Candace was abused by her birth father
