It's funny how Penny always joked about Sheldon being an alien, and in 2015, Jim Parsons actually played an alien in DreamWorks' Home.

Other people have met Howard's mother. I doubt that Bernadette would have married a complete psycho.

[josefk]

Bernadette also had conversations with Howard's mother when Howard was not in the room and in no position to impersonate her voice, so the fan theory about Howard's mother being in his mind does not work.

Mrs. Wolowitz exists. She held Raj hostage while Howard was over at Bernadette’s & and was at Howard’s wedding.

I mean, the "Penny is a spy" theory actually makes a lot of sense when you see how she lived on a Cheesecake Factory salary. That extra money has to be coming from somewhere. It would also explain why she was the only member of the cast WITHOUT a last name, until she married Leonard Hoffstetter.

I don't think Young Sheldon being his autobiography is a fan theory.
I'm pretty sure that's actually an established fact.

[Showtunediva]

I really think that Sheldon being Barney from an alternative universe makes sense.

If Sheldon is a robot how come he had kids with Amy as he mentioned in newer seasons of Young Sheldon?

[SupergirlUK]

Penny's surname is Teller, whether the writers say its Canon or not! 😅 The props department made the decision in s2 😂

What About Amy And Bernadette? How Do They Fit Into The Theory At Number Two?

[jd-zrvk]

There is an episode where Howards mother walks across a doorway. In order for Howards mother to be in his imagination, Bernadette must be a cyborg. Penny is pretty enough that she gets large tips.

[sarahvenable]

If Mrs. Wolowitz didn't exist, how would Howard have been born?

[sjstaples]

Mrs. Wolowitz dying was one of the most memorable deaths in TV.
That theory is a little infuriating.

[twiceborn_by_grace]

I could be in the worst mood but when I hear, “Who’s calling at this ungawdly owwuh?!”, I can’t help but to laugh.

Please do a supernatural fan theories one

[dimidrugg]

"It's all in his/her head": laziest fan theory ever.

[julianbigelow]

Theories like this are one of the major drawbacks of the internet.

This is just crazy sheldon theory and love it

Theory: The Big Bang Theory is based on a comic book written by David Healy that took inspiration and elements from his real life. Three characters are obvious clues to this. Leonard is an idealized version of David himself, Leslie Winkle is all the worst parts of Darlene Conner, and Mary Cooper is loosely based on Jackie Harris. Other characters and character traits from David’s real life also sneak into the comic. Penny is an idealized version of Becky Conner. Leonard and Penny getting together is a reference to Roseanne pairing them up in her book instead of him being with Darlene/Leslie. In real life David’s mother was physically and emotionally abusive to him, in the comic/show Leonard’s mom is also abusive but in the completely opposite way by being emotionally and physically distant. Sheldon is the polar opposite of his brother Mark in every way possible but serves a similar role in David/Leonard’s life. Leonard’s deep love and respect for Sheldon and constant irritation and anger with him at the same time reflect David’s complicated feelings for his brother. Sheldon’s constant presence in Leonard’s life and almost stubborn refusal for the two to separate or have any distance between them is how David deals with his brother’s passing, it’s wish fulfillment that his brother never left. Last but not least, Debbie Wolowitz’s size and screaming at people all the way across the house are of course based on David’s late mother-in-law Roseanne Conner. The gangs response to Debbie’s death is an expression of the family’s reaction to Roseanne’s sudden death.

Crazy how the 9th theory is actually true and confirmed
