The Big Bang Theory/WMG

Beverly is only half right
Leonard's mother has pointed out that Howard and Raj seem to be in something akin to a homosexual relationship, but also pointed out that Howard's circumstances make him a stereotypical Jew, maybe accounting for it. Raj...just scared of women. As the seasons, and flanderisations, have passed, Howard has acquired Bernadette and never really shown tenancies, and Raj? Raj just got more feminine to the point he is bordering on being a stereotypical 'flaming' gay man, and we know this show loves stereotypes. He likes many shows that would be considered for women (Good Wife, Sex in the City), has read Twilight which has implications of itself and always treats Howard like 'the pants' in the relationship. His attraction to Howard is blatantly obvious and only a reverse flanderisation could make him even seem heterosexual.
 * Raj's dream from the Bus Pants Utilization practically confirms this.
 * Yes. Raj repeatedly daydreaming after a woman he wishes to have a relationship with he definitely reveals he's gay. He even says, "Apart from the musical number, I'm definitely not gay."
 * It's too bad there are No Bisexuals.

Howard's mum will be played by Rosanne Barr.
Casting joke, and she's Jewish and has a nasally voice.

Howard's mum will be played by Fran Drescher.
She's Jewish and has a nasally voice.
 * Except that Howard's mother is supposed to be unattractive, if not mistakable for a man and frightening.

Howard's mum will be CGI.
The more we hear about her health problems and beauty regime, the more repulsive she becomes. By the time she actually appears onscreen she'll be so unutterably hideous that no human actress could live up to the image.

Penny's dad will be played by John Goodman.
Jossed, In season 4 episode 9, Penny's dad was played by Keith Carradine.

Sheldon's dad will be played by John Goodman.

 * Jossed. In the Luminous Fish Effect, it is revealed Sheldon's dad is dead.
 * There are always flashback episodes.

Leslie Winkle's dad will be played by John Goodman.
Because you know it makes sense.

Sheldon has Asperger's.
Come on! Just look at him!
 * Jossed. Word of God says no.
 * If Sheldon had a mental illness, then it would make laughing at his socially maladjusted antics faintly reminiscent of those Victorians who visited asylums to laugh at the inmates. You Bastard!
 * Officially, no, he doesn't. He really couldn't without it becoming a major point in the show. It would suddenly be "Oh that's awful, they're making fun of disabilities!" and they'd have to play it as sympathetic. But as one of the spergin', there are a lot of things that would indicate him as an extreme case of Asperger's. And a lot more things that are looking at a funhouse mirror version of my own tendencies.
 * Jim Parsons addresses this in an NPR interview. The writers deliberately incorporate aspects of Aspberger's into Sheldon's character, without labelling it, as stated above.
 * Asperger's isn't a mental illness; it's a higher functioning level of Autism. Calling it a mental illness is a highly controversial thing to say. You Bastard!
 * This is formally listed in the relevant section of Alternative Character Interpretation.
 * The Writers probably don't know Asperger's as well as we do.
 * Some of them don't know Sheldon as well as we do.
 * Just being smarter than the average bear and not understanding most (completely contrived) social conventions doesn't mean you're mentally ill. Sheesh.
 * While this is true, Sheldon obviously has more than just those two symptoms of the syndrome. He's very anal about his schedule, in the flashback episode he seemed to have trouble with eye contact, and he doesn't read emotions very well. All of these are major signs of Asperger's. As someone who was diagnosed with Asperger's at the age of 8 and has done plenty of research on the topic (mostly so I could fully understand why I think the way I do), I should know. (Though I'm not an expert by any means.)
 * Sheldon has also displayed a pointed tactile aversion and is asexual.
 * While the writers of the show say no, the actor who plays Sheldon nods towards Asperger's as his main inspiration for the character. For the record, this troper has Asperger's Syndrom and wasn't offended at all. In fact, he enjoys finding similarities in between Sheldon and his Aspy friends and him.
 * It's his aspie-ish tendencies that make me (an aspie) like him so much.
 * That is sort of a Self-Fulfilling Prophecy, as Parsons didn't know about Aspergers until fans kept bugging him about it. He recognizes the connections and it helped him understand his character better, but "Sheldon has Aspergers" was not part of the performance that made people think of it to begin with.

Sheldon has Intellectual giftedness.
It is not as easy as bang you are gifted enjoy your life. It also causes isolation.

Throughout the series, it seems that Sheldon had no friends before going to college at a very early age -- he only had bullies, including his twin sister. In college, he was extremely young in comparison to any peer, so he would not make any real friends at all. With time, he became (more) eccentric and had no chance to be sociable until meeting Leonard and more importantly, Penny.

Sheldon's social skills have seriously improved since meeting Penny for the first time. He even learned sarcasm.
 * This isn't a WMG. It's a known fact.

Sheldon is a Vulcan.

 * It might make an... umm... interesting plot in S7.

Sheldon accidentally shifted into a mirror universe in the arctic expedition where Vulcans are less unemotional and have Evil!Spock beards.
Mirror!Sheldon came here, and Normal!Sheldon went to the mirrorverse. They didn't notice, though, since they were busy trying to prove string theory while their associates played with the can opener.

Sheldon is not a Vulcan, he is a Minbari.
To be precise, one from the Worker Caste. Every single caste of Minbari culture cultivates one specific aspect of life, leaving everything else to the two other castes respectively. We know that the Religious Caste cultivates the emotional and spiritual life of the Minbari race, while the Warrior Caste cultivates the physical, martial and strategical capability. It makes sense to assume that the technical, mathematical and scientific knowledge is cultivated by those who would make most direct use of it: the Workers. Also, consider how Sheldon reacts to alcohol in the episode "The Pants Alternative" of Season 3. For the head bone, I suspect that he used the triluminaries to add enough human DNA to his own to make it vanish. Also, "Sheldon" is his correct name, they just constantly pronounce it wrong. It's pronounced "Shel-don" in Minbari, not "Shelden" or "Sheldn".
 * Thinking of it, this would sort of imply that Sheldon's father is also from the Worker Caste, since his mother seems to be from the Religious Caste. Also, his hate for Babylon 5 is either some sort of cosmic irony or a disguise.
 * He have first Minbari soul reincarnated among humans.
 * Implausible. We know that Minbari souls reincarnate among humans since the last Great War against the Shadows, which was around 1300 A.D.

Sheldon and Leonard were swapped at birth
Look at their mothers. Nuff said. Or alternatively, the real reason they became friends is because they subconsciously remind each other of their mothers.
 * ...this theory is possibly the only thing that could make "The Maternal Congruence" even squickier than it already is.
 * It does sound like something Leonards mother would do in some sort of weird nature VS nurture experiment.

Penny is a cousin of Socko, Spencer's friend in iCarly
Penny Blossoms aren't the first thing she's made. She sends Penny-Tees to Socko, who gives them to Spencer, Carly, Freddie and Sam.

Penny is actually the protagonist of a dating sim.
Guess the player's into the megane-type.

Sheldon has every psychological disorder known to man.
He's an Autistic Neurotic Paranoid Schizophrenic with OCD. Being Hollywood Crazy, this is the most logical explanation for Sheldon. Well, logical in TV-land.

Sheldon is actually over acting
He learned early in his life that if he doesn't take Refuge in Audacity, people just punch him in the face instead of being left speechless.
 * I know people like this. But you have ruined the show for me, curses!

The final lines of Season 3
Based on a few things that came up in The Wheaton Recurrence but were never brought to fruition:

"Penny: I love you. Leonard: I know. Penny: You quoted Star Wars. Leonard: I believe I quoted The Empire Strikes Back.
 * Kiss* "


 * Can we all get a heartfelt 'hallelujah' that this was not the case?
 * No.


 * That's likely to be a line in a season finale if not the series finale.

Wil Wheaton is the Big Bad of the series.
He claimed his grandmother was dead so he could win a card tournament, and drove a knife into the suppurating wound of Leonard and Penny's relationship just to beat Sheldon at bowling. Not only do these actions violate Wheaton's Rule, they clearly establish him as the series' main antagonist. Comic Shop Guy (Stuart) is The Dragon.
 * Alternately he didn't intentionally break up Penny and Leonard, but lets Sheldon think he did because he likes screwing around with the crazier fans.
 * Well, if I was Wil Wheaton, I'd do everything I can to destroy the lives of those who won't let me forget I'm Wil Weaton.
 * Yes, but Wesley Crusher was Sheldon's favorite character. His hatred of Wil has nothing to do with that, if it did Wil (hating the character himself) would probably sympathize more. Wil knows what an egotistical jerk Sheldon is and delights in knocking him down a peg. He's not evil, he's just doing what needs to be done.
 * Hmmmm. By messing with his friends life?
 * Except we don't know that he did it on purpose, just that he likes letting Sheldon think he did. Honestly, the breakup was coming sooner or later anyway.
 * Sheldon and Wheaton have now made peace, though this could of course be temporary.

Sheldon's Mother is Paying Leonard, Raj, and Howard to be Sheldon's friends

 * IT would explain why they seem to keep coming back after the massively hurtful comments, the ridiculous rules, the Housemate agreement...
 * Jossed Leonard sticks around because Sheldon didn't rat him out to the landlord Raj and Howard put up with Sheldon because they think Leonard's worth it.
 * He did more than that.
 * Someone who could put up with Sheldon would be a pretty cool friend for someone a little more normal.
 * It is not that hard, remember Howard's quote He came with a manual. In fact, he is so predictable that it makes it easy to avoid most of his annoyances. Oh, and he would not hesitate to lend you money if you needed it.
 * Sheldon shuts up pretty quickly when told, that makes him a lot more tolerable.
 * Not quite. a) Sheldon often tries to read emotion/behave properly. He fails (partially because of his limitations partially because it is his "hobby" not profession) but he tries. He sometimes resigns but often when he considers "the problem" as too hard. His jokes are probably bad attempts rather then malice - he read about social structure in book but he didn't grasp all nuances. b) Sheldon helps.  He lends Penny money..

Penny's last name is...

 * Candy: Because it would be sexy.
 * Worth: She's related to a certain butler. Which means Batman exists in the BBT universe, which is awesome.
 * But Sheldon is Batman!
 * Foryourthoughts: Unlikely, but possible.
 * Baggs: Just for Pun.
 * Lane: Because The Beatles are awesome.
 * Nichols: Even though it's been done.
 * Wise: Which is kinda creepy, when you think about it.
 * Arcade: Again, Just for Pun.
 * Perry: Alliteration.
 * Penny-Penny: And it turns out that Sheldon is being formal when he knocks on her door.
 * Wyatt: Because that is what her dad was called in season 4, even though he had been referred to previously as "Bob" in season 2. He is a farmer who probably goes by his last name to distinguish himself from all the other Bobs in Nebraska. Therefore his full name is Bob Wyatt, therefore Penny's last name is Wyatt.
 * Priddy: Because The Adventures of Buckaroo Banzai Across the Eighth Dimension is awesome.

Penny will break with Leonard
In reality physical attraction is hardly a base for stable relationship. The problem of finding a common topic to talk may be hard not mentioning having a totally different set of problems they have to deal in their live.

Wil Wheaton is Fawkes.
Same looks, same interests, same personality. QED.
 * Want. Because a Guild/BBT crossover would be... special.
 * Wouldn't it make more sense the other way around? We know Wil Wheaton exists as an actor in the BBT universe, maybe he just calls himself 'Fawkes' online.

Howard is Moist.
He lives in the LA area and has more than enough free time (as well as technological expertise) to act as a mad scientist's sidekick. Not to mention how his mysterious unnamed friends are always able to get him access to semi-legal defense technology and information at the drop of a hat...
 * His turtleneck probably conceals some sort of anti-persperation device.

Penny will return to college.
Her statement in the season 3 finale that, through dating Leonard, she can no longer stand dating stupid guys has the potential to be a turning point for her character. Where would she logically find smart guys? Exactly. Even if she went back for all the wrong reasons at first, it would set her up for some much-needed Character Development.
 * She certainly needs to break away from being the show's bike. Even a small acting role would be nice, just to remind viewers that she does actually have a life beyond bringing the guys food and having sex.

Sheldon is the reincarnation of Lee Harvey Oswald.
Just look at the pictures: Sheldon Cooper, Lee Harvey Oswald.

Penny's tattoo doesn't actually say "soup".
Remember the last time Sheldon tried to show off his knowledge of Chinese? He's not a reliable source.
 * Not necessarily, reading Chinese and speaking Chinese are two entirely different things. It's entirely possible that Sheldon can read Chinese and not be able to speak it, considering his Texan accent (Chinese is a largely tonal language). Hell, it's possible he was speaking Mandarin, and it was translated by someone who speaks Cantonese!

It probably says something like "aardvark" instead.

Leonard is related to Lilith Sternin.
Don't you think Leonard's mom is a lot like Lilith?

Penny's ex boyfriend from the pilot was sent to prison.
Pantsing someone in highschool = Bullying. Pantsing two adult in your apartment = sexual assault.
 * Pantsing someone that just goes away and doesn't call the police = not going to prison.

The third season rotting was intentional.
Because in the "Tangerine Factor", Sheldon says "Actually, I throught the first two renditings were far more compelling. Previously, I felt sympathy for the Leonard character, now I just find him to be whiny and annoying.". Either it's intentional, or Sheldon is a sort of psychic-fourth wall breaker. Or it's just a coincidence, but that would be just hard to believe.
 * Might be more of a Hilarious in Hindsight.

Raj is misoginistic.
He sure as hell loves making jokes at Penny's expense, and he has been shown to be an ass when he drinks. Maybe he doesn't talk to women when he's not drunk because he just doesn't have the guts to say his women-bashing out loud. It would also tie in with the idea that he's bitter about being lonely and lashes out on others.
 * True, but there is more. Raj is, for sure, an ass even when sober, and complains about having an hard life when he received everything on a silver plate. But, the one time he thought to be drunk (with analcoholic beer), acted like a charming and well mannered person, the same way he acts to his superiors. My opinion is that he is always an ass with people when he fells to be in a higher position, and being drunk is just the self-confidence booster that makes him insufferable to everyone. Technically, it's called "coward dick".

Sheldon fell for Amy for real in The Desperation Emanation
It happened just in the second Amy said "the most pragmatic thing anybody said to him". Now, I am not a fan of shamy but I think that unlike what everyone is expecting of it. This thing will start pulling Sheldon more and more into "normal people" situations.

Penny will end up in an intro-level Physics class taught by Sheldon.
Related to the theory that she's being set up to go back to school to meet smart guys. Penny would panic when she saw Sheldon enter the room, and when he began his opening lecture (the same one he began in "The Gorilla Experiment") she'll walk out of the room and go home to cry. Leonard will then show up to comfort her, and she'll tell him the story. At which point he will reveal...Sheldon doesn't get to write his own lectures any more, he memorizes lectures given to him by the University. Penny then realizes that back in "The Gorilla Experiment" Sheldon was just trying to present her with some the same basic foundation for understanding physics that any college freshman in his class would receive, and she'd failed to understand it only because she hadn't dedicated herself. She then asks Sheldon to regive the lecture, and this time listens carefully and understands.

The show will have a special or made-for-tv-movie about the gang going to San Diego Comic Con
And it will be great.
 * Hell, that needs to be the four-part Grand Finale.
 * There's going to be a four-part Grand Finale?!
 * The show's still going on with no talk of it ending anytime soon, calm down and keep your pants on.

A version of Dr. Horrible's Sing-Along Blog exists in the world of The Big Bang Theory.
Albeit not as a film, but as a cartoon drawn and written by Penny for Leonard, featuring a caricature of Leonard as the Villain Protagonist Main Character and a Friend to All Living Things Purity Sue with her own first name (although with a considerably different personality, wether this is intentional or not) as the Love Interest. Captain Hammer is a portmanteau personality of several different other ex-boyfriends of her. Bonus because Moist is played by Simon Helberg, who also plays Wolowitz in The Big Bang Theory. Penny intentionally left out a Sheldon-like character because she could think of no non-insulting way to present him, and she left out a Raj-like character because she doesn't really know him.

Raj is bisexual.
Raj has shown that he is attracted to men on several occasions, mainly Howard, but other men as well.
 * Howard/Raj allusions were present from the beginning of the series, and grew stronger with time. Maybe they're both bisexual.
 * His "definitely not gay" in the episode with his Bernadette dreams made it sound as if he'd been wondering if he was gay - and in the same episode he mentioned "accidentally" ending up in a gay bar (apparently by himself, as none of the other guys know what he's talking about)
 * Of course, we must remember that Raj wasn't raised in America, and therefore wasn't influenced as much as a born-and-raised American on gender cues and identity (i.e. girls wear pink, boys wear blue, girls play with dolls, boys with trucks) because those differences are a culture thing.

The series will end at a logical closure point

 * Penny will get back together with Leonard and fall in love again. Sheldon will marry Amy Farrah Fowler and have a baby via a surrogate. They will all live in a house together since theres no way sheldon could survive on his own.
 * Howard and Raj will realise their love for eachother and get into a menage a trois with Bernadette.

Any mistakes the writers make about geeky/nerdy subjects are deliberate.
Let's face it my friends. The writers get more obscure reference jokes right than they do wrong. When they make an error (such as calling the Green Lantern Power Battery a Green Lantern Lantern) they're doing it to deliberately mess with the fans. After all, is there anything that a "true fan" loves to do more than spot mistakes and then complain about them on Teh Intarwebz? If the writers didn't make mistakes, the fans would have nothing to complain about. They do it on purpose, people!

Sheldon is Batman.
During the Night of 1,000 Pennyblossoms, he gets hopped up on caffeine and reveals his other identity. That's why people aren't allowed in his room; they might find the entrance to the Batcave (also known as apartment 3A). Now all I need is to prove that "Penny" is just a cover for Stephanie Brown...

Stuart is the Big Bad of the series.
Follows in part from the WMG of Stuart as The Dragon and Wil Wheaton as the Big Bad. This troper is sure Stuart finally reveals himself as the true villain all along. Thinking about his character, he's very similar to Leonard, which is assumed to be why they get along so well. The difference? Leonard has Sheldon, Raj and Howard as friends, whereas Stuart is lumbered with Captain Sweatpants and the socially inept patrons at the comic book store. Leonard's friends may not be pefect, but he at least has close friends who enjoy a basic social life. Stuart becomes jealous and starts to look for ways to sabotage Leonard. He wasn't so much looking for a relationship with Penny, she was just a way to hurt Leonard. And Wil Wheaton  Not just to beat Sheldon at bowling. He was being manipulated by his friend and Mystic Warlords of Ka'a partner Stuart.

The series, or perhaps just a season, will end with Penny and Leonard moving to Nebraska.
Penny will consistently fail to get any acting work, and will decide to move back to Nebraska, just like in the Neil Diamond song "Midnight Train To Georgia" in which the female protagonist leaves LA because she can't get acting work, and her boyfriend comes with her. Of course, they wouldn't end the series on such a note, so it'll probably just be the end to a season.

Amy's character was introduced to Ship Sink Sheldon/Penny once and for all.
Despite comments by both the producers and the actors that portray Sheldon and Penny that they will never be together and that Leonard/Penny is the One True Pairing, fans have not listened and admitted defeat.

Sheldon considers Penny to be one of his closest friends (possibly the closest, considering she has done things for and knows things about him that others don't, and vice versa), but does not feel romantically inclined to her in the slightest. Earlier seasons had several Ship Tease moments between them, in particular the episode where Penny falls and breaks her arm in the shower and only Sheldon was around to help her, but as of lately they are almost non-existent.

Amy is basically Sheldon's female other half, and the fourth season has been slowly building up to move them closer and closer together, to the point where they'll probably become an actual (though still very odd) couple.

Sheldon and Leonard are the guys that bullies Ben Tennyson at school.
Just... look (picture "Cash" and "J.T.") https://web.archive.org/web/20200327101934/http://www.kaskus.us/showpost.php?p=300677214&postcount=12

Howard never had a fight with Bernadette in the season 4 finale
He just wanted to show off his gold watch Bernie got for him. Look at how he looked like he was gonna show it then and there before

Penny will want to get back together with Leonard, except this time around Leonard has lost romantic interest in her
The fourth season had been building to the fact that Penny is miserable without Leonard but too stubborn to fully admit it. Leonard has improved signficantly in the dating game, although nowhere near a "stud," but that has also resulted in him getting a little more cynical about the uncertainty of relationships. The events of the fourth season finale,, will be the catalyst for the reversal of roles.

Predictions for season 5

 * Tensions will rise with Leonard and Sheldon, as Raj was seen as a superior roomate for Sheldon than Leonard has(though Leonard could make the arguement of him being similar to that when they started out)
 * The wedding of Howard and Bernadette will be either an hour long ep or split for a two-parter
 * A sherlock holmes sytle mystery with Sheldon and Leonard as Holmes and Watson, respectivly. And Will Wheaton as the Moriarty.

Howard is not Howard
Shortly after the events of the FRIENDS spinoff series, Joey, the man we only know as “Seth” committed some crime (or was in the wrong place at the wrong time) so heinous that he had to create a brand new identity for himself. We see evidence in “Joey and the Party” that “Seth” had a thing for women with high-pitched voices (indeed, Molly sounded almost identical to Bernadette), even if Molly was not actually his girlfriend. “Seth” also mentioned to Michael Tribiani that he still shared an apartment with his grandmother. It’s very possible that his grandmother somehow found out about whatever he was involved with, and knew the necessity of a new identity, and so she agrees to go along with it, even going so far as to create for herself, the identity of the Mother instead of the Grandmother. After leaving Los Angeles and moving to Pasadena, the man now calling himself “Howard” began to deliberately dress in more and more ridiculous outfits. This is to throw off those who might be looking for the more normally dressed “Seth”. Sometime after he last appeared in "Joey," he met with a man who had a history of forging documents. He needed these documents so that he could get a job that would lend itself to his own skill set (possibly, he felt like he needed to prove he was innocent, so a job with a well-equipped university was the best place to start). So Doctor Koothrappali creates these documents, and even gives him a job in the same University that he is working at. Koothrappali and the newly created “Howard” soon meet Leonard Hofstadter, new in town, and it is from here that we see the events told in the form of a flashback in “The Staircase Implementation.” At first Koothrappali periodically would accept payments from “Howard” to buy his silence, though he has since stopped making “Howard” pay, as he has gradually come to genuinely like Howard, no doubt because he created him. Over the past 5 years, “Howard” is growing more and more comfortable with his new identity, and is less and less concerned with proving his innocence. Who knows what implications this will have when his secret comes out?

Penny suffers from slight Manic-Depression
On a web MD site, the following symptoms came up: poor judgement, promiscuity, easily distracted, poor temper control, spending sprees, talking alot, very upset, lots of energy. Now in the christmas and new years ep, its seems she hates being alone for holidays as she admits in the latter. Can't pick a boyfriend to save her life (or purposely picks losers to make herself feel better but falls in love with them, but when they break up later no matter what) and can have sex with a guy for 36 hours (annoyingly retconed to give her a high and mighty personality in "The Plimpton Solution"). She never bothers to learn to check her engine and where Sheldon's spot on the couch is (And is annoyned when corrected on it). She has a very short temper (like in the snap anger she had in "The Einstein Approximation" when she fell). More likely this brought on by environmental causes than a genetic problem.
 * That's not Manic-Depressive. If Penny wouldn't go to sleep for a few days, then had suicidal thoughts, she would be bipolar. She doesn't. Not even close.
 * How do we know/there are multiple forms of MD. You can have bipolar depression to a lesser or greater degree of severity, and also someone suffering from bipolar disorder can have episodes which are years apart, so it's possible that Penny just hasn't had a depressive episode in the time we've seen her, only a manic episode or maybe even neither. Also, there are long periods where we don't really see what Penny's up to, so she could be doing anything, including not leaving her apartment because she's having an episode. We never really knew what she did while the guys were in Antarctica, for example, and she could have spent the whole time crying into her pillow and cutting herself for all we know. I'm not convinced of this WMG, but only because there's not enough information in the show to go on. So far nothing I've seen either confirms or denies it.

The reason Raj can't speak to women...
Is because as a young child he accidentally walked into a room a his father work with a patient in a "compromised" position. this has left a mental scar that has left him only able to speak to the opposite sex when drunk. He might not even remember it.

The series finale will focus on Sheldon and Amy.
Ok, everyone knows Leonard and Penny end up together. So, where's the drama? They'll get happily married a few episodes before the finale. Then, Amy gets word that if she wants to keep her funding coming she has to marry that Saudi prince, but everyone is sad at the idea of her leaving and moving to Saudi Arabia, so somehow they get it into their heads that they have to convince Sheldon to admit he's in love with her. He'll try to keep his vulcan-like mindset, but eventually everything he's repressed will come out (the memory of the kiss is one thing, the jealousy he's expressed over Leonard showing interest in her is another). This will lead to a Race For Your Love to the airport, during which Sheldon will break every taboo he has (driving, ignoring germs...), only to find out...Amy called the wedding off the instant the Prince threatened to cut her funding, found another source, and was waiting patiently at the airport. The whole thing was a setup to get Sheldon to finally admit how he felt about her. The show ends with all the other characters arriving, kissing their love interests, and fading to black...
 * Sheldon and Amy get together and go on and on about having a baby by Artificial Insemination. In the Lab, Bernadette the Microbiologist mixes the egg and sperm. Bernadette is distracted, another chemical is in the test-tube Carmina Burana, extreme Close-Up on the Test-tube, the egg mutates into an Eldritch Abomination.
 * But it is Sheldon's 28th birthday. Sheldon and Amy are in the Lab gazing hopefully at the Test-tube, Carmina Burana. Then pon farr kicks in, Sheldon sweeps the table clear and makes mad monkey love with Amy. Slow-Motion as the Test-tube falls to the floor. Focus on the debris on the floor. Off-Screen, we hear Sheldon and Amy at it. A spider walks towards the debris and eats, spider's eyes glow red, Carmina Burana.

The show will have a bout of Cerebus Syndrome with...

 * Raj's dependence on alcohol is bound to bacfire one day.

Sheldon and Stewie from Family Guy co-operated on Time Machine and Hypno Ray
In Britain the episodes are broadcast out of chronological order: Leonard tries to get back with Priya; next, Leonard hopes to get with Penny; then, Penny moves in next-door.
 * Sheldon is using his Time Machine.
 * Stewie uses his Hypno Ray; Brits believe that E4 has a big box of episodes and pulls them out of the box at random.
 * The proof that Stewie's theory is false: videos have 4-5 episodes on them. If E4 were pulling videos out of a box, there would be 4 episodes in a row with the same continuity.

Penny's acting career will eventually take off.
Ironically, it will be a role in the kind of movie with a stereotypically nerdy fanbase (science fiction, fantasy, or super heroes).
 * Think of all the story possibilities! Autograph hunters! Sci-fi conventions! Penny having to point out several times that she is not [name of her role]!
 * It could also be a voice acting role, possibly to shed some light on how underrated voice actors are by comparison to screen actors.
 * And either Leonard or Sheldon are accidently recruited as "science advisors" for her show or movie.

Penny and Bernadette have opened a can of worms with Amy.
They basically did nothing wrong with the dress shopping, and Amy's reaction was outright pathological. They're now reinforcing her belief that she has to spend every second of every day with them, or be completely alone. Eventually, they'll have to have a sit down with her, and teach her to learn to entertain herself, and accept that they wont' always be around.

Howard and Raj opened a similar can of worms with Sheldon
Back in seasons 1-3, Sheldon would go to Penny with many problems of relating to people and other things. He even managed to develop a tad more socially with her. But then came Howard and Raj's plan to get him a girlfriend. With Amy, he soon started to go exclusively to her with his problems and acted more callously towards everyone but Amy (Lesser extent Bernadette), such as going from lack of social skills type of misunderstandings, to knowing full well what he was saying to them and getting off scott-free. Possibly since he can just wallow in his old ways with her with little need to develop, causing him to treat the gang more "Why can't you be more like Amy" interaction.

Raj has never seen Batman the Brave And The Bold
Why else would he say AQUAMAN sucks?

Rita and Zedd are Howard's parents
Here's the facts;
 * Angel Grove is in California like Pasadena
 * Rita is very shrill
 * Zedd has a hint of jewish tendencies
 * And someday Howard will grow to be Thrax

Sheldon's mother will be an antagonist for a future episode
Her general religious judgmental prejudice personality has been increasing as of late, it seems little time before she crosses a line and does something very much considered racist towards someone.

Raj will call out his parents
I really hope this because I consider them scrappies for their hatred of their kids dating white people.

Amy is bisexual.
I know that if she ever comes out they're more likely to just call her a lesbian, but still, just look at her reaction to Penny's hot dresses in The Recombination Hypothesis.
 * Possibly she sees no real difference between hetero or homosexual relationships and just wants love one way or another.
 * This is becoming a major series Running Gag -- though just to play Devil's advocate, this could also be If It's You It's Okay with respect to Penny.

Penny is really Penny Gadget
She was sent by Metro City PD to investigate scientists that have the potential to become MAD agents. (With Sheldon being the most likely candidate.) Her story about being a dumb blond, waitress is really a cover so that the 4 boys wouldn't suspect her.

Alcohol doesn't really help against Raj's inability to communicate with women.
To be precise: It's a placebo. It helps because Raj believes it does. We have seen Raj talking to women only seconds after having the first drink on several occasions. But Alcohol doesn't work instantly.
 * Yes it does.
 * We've also seen him talking to a woman (Summer Glau no less) when drinking what turned out to be non-alcoholic beer, so this was confirmed a while ago.

The five of them are destined to have a five-some together
Hence the title of the show.

Bernadette and Howard will not get married at the end of season 5
Mayim Bialik said in an interview that there WILL be a wedding, but maybe not the one we'd expect. This could be a joke, but it could also be Leonard and Penny accidentally ending up married, or, for more laughs, Sheldon and Amy.
 * Jossed

The entire thing is just a dream
The whole series turned out to be just an over-thought hypothesis by Leonard and/or Sheldon of whether or not they should talk to the﻿ new girl who moved in across from them. "Hi, I'm Leonard, and this is my roommate Sheldon."
 * I hope this is true so the last words of the series can be:

"'' Oh, hi, I'm Penny. Penny [her last name]..."
 * And that's how Penny's last name going to be revealed:

The Elevator will be fixed in the series finale
To represent change or an ending.

Sheldon gets a lot more than he lets on.
Oh, he's still pretty naive, but sometimes he realizes what's going on but just runs with it for his own amusement.
