One of the best parts about long-running TV shows is how attached fans get to the characters. After tuning in night after night, we get to know the characters like they’re our own friends and family members. Over time though, fans begin to put together theories that could very well translate into the show’s universe. In fact, some shows may even be in the same universe as other shows.

Below we have 10 of our favorite shows and theories that are so strong, it’s hard to not believe they have some validity to them! Scroll down to see if your favorite show made our list.

DO WINNIE-THE-POOH AND HIS FRIENDS ALL HAVE PSYCHOLOGICAL DISORDERS?

Deep inside Hundred Acre Wood, a little boy named Christopher Robin had some of his best friends living in this mystical land. There was Pooh Bear, Piglet, Tigger, Eeyore, Kanga, Roo, and so many more. Together, this group of buddies lived in friendship and harmony.

However, according to Digital Spy, the Canadian Medical Association saw a link between the characters and popular psychological disorders. Eeyore represented depression, Piglet was anxiety, Owl was very dyslexic, Tigger was ADHD, and Pooh Bear was a mix of ADHD and OCD. Did these animals showcase how Christopher Robin was feeling on the inside?

THE SCOOBY-DOO GANG IS ON THE RUN

Scooby-Doo was such an awesome cartoon, showing us a group of teens hunting down “ghosts and monster” with their dog, Scooby. However, was this foursome really after ghosts or were they always on the run because they themselves were running from something?

A person on Reddit has a conspiracy theory that the teens were actually running away from the draft. Considering the show released in 1969 (the same year of the Vietnam War), this person thinks the gang headed north to Canada to refuse going to war.

COUNT VON COUNT IS THIRSTY FOR HUMAN BLOOD

Did you know Sesame Street is on its 50th season?! For 50 years, we’ve been falling in love with characters like Big Bird, Grover, the Cookie Monster, and learning so much about everyday things. However, one thing we did not learn was that Count von Count might have fed on the blood of children…

As a vampire, there’s a theory out there that Count sucks the blood of the children on Sesame Street. After getting kids into his lair where he teaches them numbers, he feeds on them and that’s why there are always new kids on the show.

THE GOOD PLACE AND PARKS AND REC COULD BE IN THE SAME UNIVERSE

One eagle-eyed fan of The Good Place noticed a small hint that may twist everyone’s brains into a pretzel. The magazines Eleanor is reading has two dead giveaways connecting it to the Parks and Recreation universe. Does this mean The Good Place took place around the same time Leslie Knope was in office?

With a celebrity baby discussion on the front cover, the back covers had champagne that Jean-Ralphio Saperstein created. The other was an aftershave created by perfume creator Dennis Feinstein. Even weirder, Jason Mantzoukas who plays Feinstein in Parks and Rec. is also in The Good Place.

ARE THE KIDS IN THE RUGRATS ALL PART OF ANGELICA’S DAYDREAMS?

In Nickelodeon’s Rugrats, Angelica and Tommy are cousins, whereas Chuckie, Phil, and Lil are their buddies. And while the entire plotline for the show is to follow these little friends on their adventures, perhaps Tommy, Chuckie, Phil, and Lil weren’t even real. What if star-gazing Angelica made them up?

There’s a fan theory out there saying that all of the kids and adventures are an invention of Angelica’s imagination. She’s bored and lonely and comes up with in-depth stories as if they were real.

DOES CHARLIE BROWN HAVE CANCER?

The last thing we want to imagine is that our favorite Peanuts character has cancer, and yet, this is a fan theory that’s been passed around.

Due to Charlie being bald (with one sad hair curling on top), the theory posits he has cancer and that everything we see in the show is made up in his own mind as he lies in the hospital sick. Other fans have gone on to say that the creator Charles Schulz would never have that happen to Peanuts’ strongest hero, but who’s to say?

IS TOBY THE SCRANTON STRANGLER?

Throughout The Office’s run, we were introduced to Scranton’s nightmare: the Scranton Strangler. He was this deranged man on the loose killing people and the entire gang couldn’t wait for him to be snatched off the streets.

Funny enough, Toby ended up being one of the jury members on the murder trial for the Scranton Strangler, which was quite fitting due to his obsession with the villain. But what if Toby wasn’t just fond of the whole story, maybe he was the whole story? After all, after convicting the guy who they thought was the Strangler, Toby admitted to sentencing the wrong man to jail…

ARE MAX AND RUBY DEAD?

Max and Ruby is an adorable TV show on Nickelodeon. Focusing on a very well-mannered older sister Ruby and her fun-loving younger brother Max, we see the everyday shenanigans these bunnies get themselves into.

Oddly enough, the bunnies’ parents are nowhere to be found. Were these bunnies left behind? Think again. There’s a theory out there that these two bunnies are actually dead. That’s why we never see their parents but we do see their grandmother from time to time.

DEXTER REALLY WAS A MAD SCIENTIST

Dexter’s Laboratory was such a fun show. With an incredibly smart boy named Dexter and his overzealous (and complete opposite) sister named Dede, we saw how Dexter lived in a normal world with such an incredible mind (and laboratory).

One theory claims that Dexter accidentally killed his family in a science project gone wrong. To make up for the family he killed, he made a new laboratory family, which is why they’re all a little… well, dumb.

IS THERE A CONNECTION BETWEEN BREAKING BAD AND THE WALKING DEAD?

This is a popular theory that’s been filtering around for some time. Is the blue meth created in Breaking Bad the reason a future zombie apocalypse erupted? And if so, does this mean The Walking Dead is actually in the same universe as Breaking Bad? The one theory suggests when a person overdoses on the blue meth, they’re resurrected in zombie form. Other fans have even found small traces of Breaking Bad in The Walking Dead.
