Love Appears on and off Set of the Big Bang Theory: Find out Who’s Dating Who

As it goes on many long-running shows where cast members are together for most of the day every day, relationships form, both on and off screen. The most talked about relationship was between Leonard, the experimental physicist, and Penny, the aspiring actress who lives next door. Penny would usually only date tall and muscular men, but she ends up falling in love with Leonard and the two date on and off until they got married.

It’s easy to forget with a show as good as this, that these TV stars are acting and that in real life they have their own relationships. Believe it or not, the TBBT cast are quite different from the characters they portray on screen. And they date all kinds of other celebrities. Let’s see which cast members dated who. And some even dated each other off screen.

The pair were seen together on a romantic holiday in Maui. We don’t know much about Ariella, but we do hope to get more details in the near future.

Cast Read-Throughs

Getting the perfect amount of laughs on ‘The Big Bang Theory’ is a serious task. One of the most important steps is a cast read-through. Before an episode goes into production, the cast and writers sit down to read the script together.

Source: Pinterest

With only 5 production days assigned per episode, writers need as much time as possible to perfect the script before it goes into filming. Changes might be insignificant, but it comes out to about 20% to 30% of the script will be brand new by the time it goes into filming.

The Jedi Is In the House

The ‘Big Bang Theory’ has its random cameos from a galaxy far, far away. Someone who’s no stranger to the cameo is Luke Skywalker himself, Mark Hamill. The Jedi even showed up on the show’s season 11 finale to officiate at Sheldon and Amy’s wedding.

Source: Reddit

The cast members took turns taking photos with the science fiction legend, including Kunal Nayyar, who plays Raj. One super-fan, Mayim Balik, was particularly excited by Hamill’s visit. She made a video shouting, “Mark Hamill’s here! He’s here. He’s on our stage, he shook my hand… I can’t handle it! I can’t sorry… I thought I could keep it together, but I can’t!”

Stephen Hawking Cameo

Stephen Hawking was the greatest physicist who ever lived. Period. His book A Brief History of Time brought quantum physics to a wide audience. Hawking even had time for a celebrity cameo on the show.

Source: Pinterest

Funnily enough, he played a self-centered version of himself, irritating Sheldon over his erroneous theories on the Higgs Bosan particle and being a sore loser on Words with Friends, and even not inviting Howard to a pizza party after proving him wrong about ‘The Matrix.’

200 Episodes

Only a few shows get to enjoy the longevity that ‘The Big Bang Theory’ has had. And even fewer have managed to keep the on and off again relationship saga between main characters. Think Rachel and Ross in ‘Friends’ or Pam and Jim in ‘The Office.’

Source: inerd4u

The relationship between Penny and Leonard has been a major plot point throughout the show’s long run. By the 200th episode, the couple were still getting over the break up from their Vegas marriage.

Meeting Spock

Sheldon Cooper is known for being a big ‘Star Trek’ fan. But in real life, Jim Parsons has never seen an episode of the series or its numerous spinoffs. But Parson’s is a convincing Trekkie, especially when his character has dreams about it.

Source: Reddit

Parson enjoyed hanging out with the late and missed Leonard Nimoy when the actor appeared in episode “The Bath Gift Item Hypothesis.” Here, they’re both giving a Vulcan salute.

Jim and Mayim

Mayim Balik joined as a cast regular in season 4, along with Melissa Rauch. The behinds the scenes relationship with her on-screen husband looks like a good one, where the two are often goofing around on set.

Source: Pinterest

Their on-screen relationship has had its ups and downs, and viewers must have asked themselves what does Amy really see in Sheldon. But there’s a reason for everything!

Wedding Guests

The wedding of Amy and Shelton had its share of famous faces, including Kathy Bates and magician Teller as Amy’s parents. There was also Jerry O’Connell and Will Wheaton at the congregation. Mark Hammill married the pair as a favor to Howard for finding his dog.

Source: inerd4u

Steve Holland described it: “Mark was everything you’d want him to be. He was hilariously funny… It was really just a dream come true.” The episode also had a bittersweet part when Sheldon received a pocket watch from Stephen Hawking that was sent before his passing.

Meeting Data

In the 5th season in the episode titled “The Russian Rocket Reaction,” Leonard decides to attend a party with Sheldon’s enemy, Will Weaton. Not only did the recurring guest star make an appearance but Brent Spiner, who played everyone’s favorite android Data, also joined.

Source: inerd4u

Spiner shows up to the party that the gang go to with Wheaton, continuing the running gag that all former Star Trek actors are desperate for money. Sheldon was reluctant to go but is persuaded by the promise of meeting one of his Star Trek heroes.

Kaley’s Broken Leg

Kaley Cuoco broke her leg during a horse riding lesson when the horse Cuoco was riding got scared and threw the actress to the ground. She got up and laughed it off. The horse then turned around and tried to jump over Cuoco and ended up landing on her left leg. Ouch!

Source: Pinterest

Cuoco told Ellen DeGeneres on her show what happened next: “Then I looked, and I’m like, wow, my foot’s facing me… And I was like, that’s not normal.”

Achieving Lift Off

The season 5 finale, “The Countdown Reaction,” was out of this world. Literally. Caltech engineer Howard got to fulfil his wish and blast off into space. This only made him insufferable in season 6, but at least he got to have one up on Sheldon.

Source: inerd4u

Next to him was real-life astronaut Mike Massimino. The former astronaut was there to offer technical pointers and he was impressed with the level of detail that went into making the launch scenes as realistic as possible.

Actual Scientists

David Saltzeberg (right) is the brains behind most of the science that you see on the show. The UCLA professor became the show’s principal scientific advisor. He makes sure the white board equations are correct and actually reflect the current scientific trends.

Source: nhpr

Fun fact: each script comes to Saltzeberg with the words “Insert Science Here” written where some brainy dialogue needs to go. He’s also on set for each live recording in case the producers have a question or need to check the accuracy of jokes rewritten on the go.

Star Trek Meets Star Wars

The worlds of Star Trek and Star Wars are two that rarely cross, except when J.J. Abrams directs portions of both franchises. On The Big Bang Theory, fandoms often collide. When Sheldon and Amy got married, Mark Hamill officiated while Sheldon’s arch-nemesis Will Wheaton sat in the audience.

Source: inerd4u

Hamill looks like he’s using some powers from the dark side with the former Starfleet cadet. Maybe Luke’s recent change into a glum figure in ‘The Last Jedi’ rubbed off on Hamill.

Testing Jokes

The writers’ room is where the team works on scripts until they are a near-perfect mix of jokes and drama. Then there’s the cast read-through, fine tuning it even more. But the only time the producers will know if the jokes are cause for laughter is when they are performed in front of a live audience.

Source: Pinterest

If a joke works, it’s perfect. But if a joke fails, it will be worked on and retested on the audience again. Sometimes different punchlines are tested out or slight tweaks are made.

He Thought He Was Auditioning For A Game Show

Jim Parsons got the call to audition for a “new show produced by Chuck Lorre.” He wasn’t familiar with the writer/producer at the time, thinking he would be auditioning for Chuck Woolery, the host of numerous game shows.

Source: inerd4u

In 2014, Parsons explained to David Letterman that he thought he was trying out for a game show, jokingly saying, “I thought, ‘why are they so excited about it?’”

The Show Had a Different Theme Song

The opening theme song for ‘The Big Bang Theory’ is fully engrained in your heads now, so it’s hard to imagine the show without it. “The History of Everything” that was composed and performed by the Bare Naked Ladies is played after the cold open of each episode.

Source: Pinterest

But the first pilot episode was Thomas Dolby’s 1982 hit “She Blinded Me With Science” as the theme song instead. You’re probably glad it was changed though.

Opening Credits Typo

For those with a sharp eye, you might have noticed an unexplained typo in the opening credits. In the timeline that scrolls by on the screen while the theme song is playing, the dates read 93,000BC 92,000BC and then 91,0009C.

Source: Pinterest

It may be a simple typo, which can be harmless, but it just doesn’t fit the show! They’re all about getting things perfectly accurate!

Speaking of typos, see some of the funniest ones, here.

Episode Names

Every episode has its own title and maybe you haven’t paid much attention to them, but you might want to know about them. The purpose behind each episode title is to represent a different scientific theory.

Source: inerd4u

In fact, it would be difficult to distinguish the real scientific statements from only the episode names, but if you wanted to, you could figure it out.

The ‘Soft Kitty’ Lawsuit

Remember Sheldon’s soothing song, “Soft Kitty?” Sure, it sounds original, but in December of 2015, the daughters of a nursery school teacher who wrote an almost-identical verse in the 1930s filed a lawsuit against “The Big Bang Theory.”

Source: Pinterest

Can you believe it? A judge ended up dismissing the case, as the family failed to show they held a copyright on the lyrics.

Penny’s Last Name?

Even the biggest TBBT fan can’t tell you Penny’s last name. This is because the writers have intentionally withheld the information. In a 2013 interview, executive producer Steve Molaro said,

Source: inerd4u

“What name could we possibly pick that would be satisfying at this point? You know, I don’t think we will [reveal it]. We’re kind of a superstitious lot here. We’ve made it this far without knowing Penny’s last name. I think we’re good not finding out.”

A Different Title

Did you know that the original name of the show wasn’t “The Big Bang Theory?” The original working title was actually “Lenny, Penny and Kenny.” Yes, it’s true. And hilarious.

Source: Pinterest

To pitch the show, co-creators and executive producers, Bill Prady and Chuck Lorre, wrote a script together. They recruited some of their actor friends to play it out for CBS executive Les Moonves, and the rest is history!

There’s a Belarusian Version

Did you know that there’s a Belarusian version of the show? A Belarus production company created a show called “The Theorists,” which was a total copy of “TBBT.”

Source: Physics Napkins

In February of 2010, Chuck Lorre wrote: “When we brought this to the attention of the Warner Brothers legal department, we were told that it’s next to impossible to sue for copyright infringement in Belarus because the TV production company that is ripping us off is owned and operated by the government of Belarus. Having no other recourse, I’m hoping that this vanity card will be read by the fine folks making ‘The Theorists,’ and, wracked with guilt, they break down and send us some felt hats.” “The Theorists” was canceled shortly after that.

A Long-Running Joke

The crew is full of practical jokers that love to have fun on the set. As they should! Show writer Stephen Engel loves to prank his colleagues and, when he succeeds, he would shout, “Bazinga!”

Source: inerd4u

The catchphrase from the writer’s room wasn’t at first written into any scripts, but it eventually became a popular catchphrase on the show. And now you know why!

The Bazinga Bee

A researcher in Brazil, Andre Nemesio, has discovered different species of orchid bees. Since some types are endangered, he tends to give the newly-discovered insects catchy names to help attract more attention to bee research.

Source: Wikipedia

Nemesio named one of the species “Euglossa bazinga” hoping that the Hollywood name would garner some attention. And you know what? It did! What a smart cookie.

The Bazinga Jellyfish

In 2011, scientists discovered a jellyfish off the eastern coast of Australia. Considering it’s so tiny, about the size of a grape, researchers believe it was formerly overlooked as a child of another species.

Source: Wikipedia

They called it “Bazinga rieki,” partly because the body resembles a seven-string harp called a bazinga. But also because it had tricked them by hiding in plain sight! Just like a practical joke. Hence, the term bazinga.

Bernadette’s Voice Is Phony

Sometimes, actors need to find creative ways to stand out in auditions if they really want to land the part they’re going after. And Melissa Rauch did just that. When she auditioned for the role of Bernadette, she decided to stand out.

Source: inerd4u

How did she stand out? Well, she chose to use a distinctive voice. “That’s actually my real voice and this is my fake voice,” she joked during a Comic-Con panel. Could you imagine Bernadette any other way?

Leonard’s Glasses are Also Fake

Yes, it’s obvious that Leonard wears glasses. But, if you look closely, you’ll see how his glasses are actually lens-less. Johnny Galecki chose to wear glasses intentionally because he thought they suited Leonard’s character.

Source: Pinterest

So then why are they lens-less you ask? Because the lenses reflected the lights during filming. So Galecki solved the issue by simply just popping out the lenses.

Who Else Wears Glasses?

Leonard is the only male main character who wears glasses. And on the flip side, Penny is the only female main character who does not wear glasses. But Mayim Bialik is the only cast member who wears them in real life.

Source: Pinterest

Fun fact for all the newer generations: TBBT isn’t Mayim Bialik’s first rodeo. Those born in the 80s (or earlier) will remember her from her hit TV sitcom ‘Blossom.’

Props to Props

Actor Wil Wheaton has been on “TBBT” more than a dozen times. And in 2010, he took a photo of the coffee table in Leonard and Sheldon’s apartment and shared it on his personal blog.

Source: Physics Napkins

“This is an example of the attention to detail that is everywhere on every set of ‘The Big Bang Theory,’” he wrote. “It would be really easy to just toss a few random magazines and soda cans there, because it’s very unlikely that they’ll ever be seen in this much detail, but at every level of production, they make a concerted effort to ensure that everything is authentic.”

What’s in a Name?

Do you know why Sheldon and Leonard were given those specific names? Producers chose them to honor the classic “Dick Van Dyke Show” producer Sheldon Leonard. Also, Leonard’s last name is Hofstadter.

Source: inerd4u

That’s because Robert and Douglas Hofstadter (a father and son pair) were notable scientists. And then there’s Leonard’s middle name, Leakey, after the famed paleontologist Louis Leakey.

Jim Parsons’ Musical Ability

Do you know what a theremin is? It’s okay, many people don’t. A theremin is a unique musical instrument that is played without being touched, that is until watching “TBBT.” In real life, Parsons is actually a piano player.

Source: Pinterest

But the theremin, Leonard’s instrument of choice, was new to him. But he took on the challenge and learned how to play the electronic instrument for the show. And we’re glad he did!

Money Talks

Jim Parsons, Johnny Galecki and Kaley Cuoco make a hefty amount per episode. How much? $1 million dollars per. Each episode! That means they will make $23 million for one season. The rest of the cast make a lot, but not the same amount.

Source: inerd4u

The rest of the main cast makes $750,000 per episode. Bialik’s and Rauch’s episode fee went from $20,000 to $100,000 per episode. Parsons, Galecki, Cuoco, Nayyar and Helberg have all agreed to take a $100,000 salary cut for the next two seasons to release $500,000 to raise Bialik and Rauch’s salaries.

Sheldon’s Shirt Color Clues

Have you been able to notice the difference Sheldon’s shirts have on his mood? Clever “TBBT” fans have noticed that the shade of Sheldon’s shirt often corresponds to his mood.

Source: Physics Napkins

So if he’s wearing a red t-shirt, it might mean that he’s going to be angry in a scene. And as a superhero fan, Sheldon is particularly fond of his Green Lantern and Flash shirts.

A Nod from the Flash

Sheldon Cooper, who loves the Flash, has been giving nods to the character over the years. And the amazing thing is that the Flash is also making his gestures to the show.

Viewers of the TV show “The Flash” have seen the character Cisco Ramon, played by Carlos Valdes, wearing shirts with “TBBT” inside jokes or catchphrases on them. That’s respect!

Penny’s Purse

Ok ladies, and maybe gents: who has noticed that Penny hasn’t changed her purse yet? Fashion fans, or those who just pay attention to detail, will notice that Penny has been carrying the same purse since Season 1, episode 2.

And it’s been going on for 12 years! Apparently, it’s a Lucky Brand slouch hobo bag. She must really love it and has no intention of getting rid of it. Clearly!

Apartment Easter Eggs

Amy Farrah Fowler lives in apartment 314, and do you know why? We assume that it was no accident, considering that the value of pi in decimal form is 3.14.

Wil Wheaton’s house number is 1701, which is also the same as the U.S.S. Enterprise’s hull number on “Star Trek: The Next Generation.” Wheaton, of course, was an actor on “TNG” from 1987 to 1994.

The Science Advisor

Physicist David Saltzberg, the show’s official science advisor, takes his job seriously and admits to being scared of making any mistakes. He said in an interview, “People will randomly meet up with me and say,

‘You know, I really appreciate that the science is correct,’” Saltzberg stated. “And the truth is, I’m just living in terror of making a mistake because I know I’ll get a hundred emails if anything is wrong.”

Jim Parsons Failed Science Class

It’s probably a good thing that a real physicist is on-set for fact checking because Parsons admitted to not being so good at science. He told Time magazine that the one class he failed in college was a science class (meteorology).

Oh, the irony. And on the flip side, Mayim Bialik is a real-life neuroscientist! Maybe she can enlighten Jim on some of her science knowledge.

The NASA Team

This was a truly memorable moment for the whole cast and crew of the show. The real-life NASA scientists, who were responsible for the Mars Curiosity rover landing, visited the “Big Bang Theory” set.

The question is which group was more star-struck? The Big Bang crew clearly appreciate NASA, but it looks like NASA is also a fan!

Locating Apartment 4A

Leonard and Sheldon’s apartment 4A is one of the most recognizable sets on television. The two roommates have mentioned that it’s in Pasadena at 2311 Los Robles, across the street from the Colorado Avenue Chevron station.

Or so they say…While these streets and places d actually exist, the actual apartment is nowhere to be found. So don’t bother looking for an apartment at that exact location.

Adam West

Adam West guest-starred on the show’s 200th episode. He had the line, “Don’t ring my doorbell or my poodles will go crazy!” during a scene.

After rehearsing his line, West asked executive producer Steve Molaro, “Do you think I could have a tougher dog, like a Rottweiler?” But funnily enough, West had poodles in real life.
