This Simple Big Bang Theory Quiz Will Stump Most Fans

Everyone knows the story about how the whole universe was in a hot, dense state then nearly fourteen billion years ago expansion started, but not everyone will be able to pass this simple Big Bang Theory quiz with flying colors. In fact, some might find the following questions as hard to solve as one of Sheldon’s whiteboard equations – which, by the way, are written by actual scientists.

(A fact that only the truest of fans would have already known.)

It doesn't take a rocket scientist to pass this quiz, just a true fan of The Big Bang Theory. But viewer beware; these questions might start out as simple as Penny’s ex-boyfriend Zack, but quickly grow as complicated as Leonard’s relationship with his icy but brilliant mother, Dr. Beverly Hofstadter.

Anyone who fancies themselves a Big Bang buff needs to take this quiz immediately to prove that they’ve earned their Ph.D in Big Bang Theory. From roommate agreements and relationship disagreements to friendships and fandoms, this quiz covers it all. It might sound simple, but this one is bound to stump even the most devoted of fans.

Math, science, history, let’s see who can unravel the mystery that all started with a Big Bang.

Question 1

What is Penny's maiden name?

After a relationship filled with major ups and downs – these two practically invented the term “breakup to makeup” – dream girl next door Penny finally marries Leonard when the pair eloped to Las Vegas in The Big Bang Theory season nine premiere. Or maybe he just wore down her resistance. Either way, their nuptials made her officially Mrs. Leonard Hofstadter. But what was the aspiring actress and Cheesecake Factory waitress turned pharmaceutical sales representative’s maiden name before she became Mrs. King of the Nerds?

Question 2

What is Sheldon's catchphrase

Every great sitcom character deserves a great catchphrase. Homer Simpson has “D’oh!” Steven Urkle always asked: “Did I do that?” Joey Tribbiani from Friends was famous for inquiring, “How you doin’?” Who could forget Jan Brady’s exasperated uttering of “Marcia, Marcia, Marcia!”? Or Jerry Seinfeld’s faux-friendly greeting of “Hello, Newman,”? Dr. Sheldon Cooper of The Big Bang Theory is certainly no exception to the rule. Sheldon’s one-word catchphrase is more than memorable, it’s officially a part of the pop culture lexicon. What is Sheldon’s catchphrase?

Question 3

How many times does Sheldon knock on Penny's door and say her name?

Sheldon’s feelings about Penny might have been pure exasperation when she first started hanging around his apartment, but his frustration eventually grew into one of his deepest friendships on the show. Sheldon frequently finds himself going to Penny for all kinds of things, from advice about relationships to acting lessons, and he has a very particular way of reaching out for help when he needs it. Exactly how many times does he knock on her door and say her name?

Question 4

Which of the following isn’t a game made up by one of the Big Bang guys?

Sheldon, Leonard, Raj and Howard are well-known for spending a significant amount of time playing games. Everyone knows about the guys’ love for role playing games like Dungeons and Dragons and The Settlers of Catan, but the crew also spends plenty of time playing video games like Halo, World of Warcraft and Rock Band. They’ve even been known to invent a game or two of their own to pass the time. Which of the following isn’t a game made up by one of the Big Bang guys?

Question 5

Where did Howard get his Master's Degree?

Poor Howard Wolowitz gets no respect. He lived at home with his mother way into adulthood, his batting average with the ladies was zero (that is, until Bernadette came along), and his lack of a Ph.D is an endless source of mockery from super-degree'd, super genius, Sheldon Cooper. Not even a plumb assignment designing the “space toilet” for the International Space Station and an actual stint as an astronaut in outer space can save him from Sheldon’s ribbing. Despite Sheldon’s constant dissing, a Master’s degree in engineering is quite an accomplishment. Where did Howard get his Master’s degree?

Question 6

What was the preceding event that got Sheldon to make Amy his official girlfriend?

Sheldon Cooper and Amy Farrah Fowler, or Shamy, is the second least-likely couple in the entire cast. (Seriously, who expected a guy like Wolowitz to end up with someone like beautiful, brainy Bernadette?) Viewers swooned along as Sheldon and Amy’s platonic relationship upgraded from boy-slash-friend-slash-girl-slash-friend status to actual boyfriend and girlfriend. Watching Sheldon come out of his shell and connect emotionally with Amy has certainly been a delight. What was the preceding event that got Sheldon to make Amy his official girlfriend?

Question 7

At what age did Sheldon start going to college?

Sheldon Cooper is a bonafide genius and he makes sure everyone around him knows it. He displayed his Einstein-like savant capabilities from a very young age. He has an impressive number of degrees hanging on the wall including his Bachelor of Science, Master of Science, Master of Arts, Doctor of Philosophy, and Doctor of Science – quite the feat for someone under the age of forty, but Sheldon got an early start. At what age did Sheldon start going to college?

Question 8

Which Star Trek: The Next Generation star wound up on Sheldon’s mortal enemy list after he forgave Wil Wheaton?

Sheldon Cooper is a pretty intense guy, but he’s not crazy – his mother had him tested. That said, he is a grown man with an actual mortal enemy list. Co-worker Barry Kripke; Leonard’s former flame Leslie Winkle; and child physics prodigy Dennis Kim have all earned a place on his mortal enemy list. But nobody rankled Dr. Cooper quite like Star Trek alum Wil Wheaton, whose failure to show at the 1995 Dixie Star Trek Convention began a decades-long feud. The pair would eventually make peace, and a different Star Trek actor would take Wheaton’s place on the notorious mortal enemy list. Which Star Trek: The Next Generation star wound up on Sheldon’s mortal enemy list after he forgave Wil Wheaton?

Question 9

Exactly how many seconds long is the extra footage in Raiders of the Lost Ark that the guys wait in line to see?

Nobody ever accused the guys of The Big Bang Theory of not being committed to their favorite fandoms. After all, Sheldon and Leonard once waited in line for fourteen hours to see the midnight premiere of Star Trek: Nemesis. So, of course when an extended cut of Raiders of the Lost Ark arrives in theatres, it’s a must-see for the guys – the extra footage will finally resolve the submarine controversy. Exactly how many seconds long is the extra, never-before-seen footage in Raiders of the Lost Ark the guys that wait in line to see?

Question 10

What present did Sheldon buy Amy to win back her affection after a fight?

Amy Farrah Fowler is more than just Sheldon’s love interest, she is an accomplished scientist in her own right. Her social awkwardness and genius-status make her the perfect companion and life partner for Dr. Sheldon Cooper, but their relationship wasn’t without it’s highs and lows. Sheldon’s constant inability to acknowledge Amy’s feelings was a frequent source of conflict in their relationship. Although Sheldon often struggled with making it up to Amy, sometimes he did get it right. What present did Sheldon buy Amy to win back her affection after a fight?

Question 11

Who was the first woman Raj spoke to without liquid courage?

Despite being tall, dark and handsome with a charming accent, Rajesh Koothrappali has never had it easy with the ladies. In early seasons, Raj suffers from a selective mutism that prevents him from speaking to women. He eventually finds that a few alcoholic beverages can lower his inhibitions and self-consciousness just enough to hold a conversation with the ladies. This strategy eventually backfires on Raj and he is forced to speak his first words to an actual human woman. Who was the first woman Raj spoke to without the help of alcohol?

Question 12

Finish these Soft Kitty song lyrics: “Soft kitty, warm kitty, little _ _ _”

Penny and Sheldon have such a sweet friendship. When a very needy Sheldon finds himself stricken with a cold, he also finds himself with nobody willing to take care of him – except Penny. After he turns up at The Cheesecake Factory for soup, Penny takes Sheldon home and tucks him in. She even sings his favorite song that his mother would sing to him when he was sick as a child, Soft Kitty. Finish these Soft Kitty song lyrics: “Soft kitty, warm kitty, little ___”

Question 13

In The Cooper Extraction, what does Leonard show Amy to prove that she really is special to Sheldon?

Sheldon Cooper is not exactly the romantic type. Frankly, that he and Amy Farrah Fowler ever made it to the altar is nothing short of miraculous. Their relationship definitely had its ups and downs, particularly when it comes to Amy’s need to feel valued by Sheldon. He cares very deeply for her, of course, but has his own way of showing it (or not showing it, really). In The Cooper Extraction, what does Leonard show Amy to prove that she really is special to Sheldon?

Question 14

What was the name of Howard and Raj's filk music band?

Raj and Howard are the kind of best friends who do all kinds of things together, like starting a filk music (folk music meets sci-fi) band. With songs like “Thor and Dr. Jones,” “Color Pulse,” and “Fest Zest,” how could they not be a hit? Their band booked gigs at Stuart’s comic book store and even a Bar Mitzvah. Eventually, they add Caltech geologist Bert Kibbler to the lineup, making the duo a trio. What was the name of their filk music band?

Question 15

What was the name of the video game Penny can't stop playing?

Penny might be a successful pharmaceutical sales rep now, but she didn’t always have it so good. Trying to make it as an actress in California wasn’t easy, and after a series of professional and personal failures that culminated with swallowing a fly, Penny found herself at her lowest point – addicted to online gaming. With Sheldon as her guide, Penny embarks on a series of fantasy quests and her obsession with the game grows exponentially. What was the name of the video game to which Penny gets addicted?

Question 16

Why is Sheldon, Leonard, and Penny’s building elevator out of order?

Taking the stairs is a great way to get extra cardio, but the characters on The Big Bang Theory aren’t hoofing it up four flights every day for their health – their apartment building’s elevator is perpetually out of order. Regular viewers are used to seeing the cast carry on conversations while they stomp up the stairs, but how many know exactly how the elevator came to be blocked off with yellow caution tape? Why is Sheldon, Leonard and Penny’s building elevator out of order?

Question 17

Which of the following is not a clause in the Roommate Agreement?

Sheldon isn’t the easiest guy to live with, but somehow, he and Leonard made it work. This, of course, is due mostly to Leonard’s saint-like levels of patience and Sheldon’s commitment to enforcing the rules contained within the famed “Roommate Agreement.” Sheldon was nothing if not thorough in crafting the document, which contains numerous clauses and addenda that address everything from the temperature on the thermostat to Sheldon’s seat on the couch. Which of the following is not a clause in the Roommate Agreement?

Question 18

How did Sheldon and Amy meet?

Sheldon Cooper and Amy Farrah Fowler are among the most beloved couples in television history. Like Luke and Laura on General Hospital, Jesse and Rebecca on Full House, and Jim and Pam on The Office, Sheldon and Amy’s wedding wasn’t just another episode – it was a full-blown television event that was years in the making. The world loved watching this unexpected couple fall in love. Every great love story has a great beginning, and Sheldon and Amy are no exception. How did Sheldon and Amy meet?

Question 19

What was the name of Penny's business?

Penny is more than just an actress-slash-waitress turned pharmaceutical sales rep. For a very brief period of time, she was also an entrepreneur. With the help of Sheldon, Leonard, Howard and Raj, Penny ran an e-commerce site selling flower barrettes. The business was short-lived as Penny and the gang weren’t exactly optimized to fulfill orders for thousands of the barrettes, but she still can put “business owner” on her resume alongside “commercial actress.” What was the name of Penny’s business?

Question 20

What apartment do Leonard and Sheldon live in?

Sheldon and Leonard’s apartment is basically ground-zero for all of the drama and hijinks on The Big Bang Theory. It’s where the guys gather to play video games and Dungeons and Dragons. And where the entire gang comes together for regular family meals of Chinese takeout. It’s where Leonard and Penny fell in love, and where Sheldon learned to be a better friend and boyfriend. Their apartment is so central to the show that it’s basically a major minor character. What apartment do Leonard and Sheldon live in?

Question 21

Which of the following are Dr. Beverly Hofstadter's two professions?

So many of Leonard’s issues and insecurities with women can be chalked up to the distant relationship he has with his icy and overly analytical mother, Dr. Beverly Hofstadter. That she gets along so famously with the socially challenged Dr. Sheldon Cooper is really just another piece of Leonard’s unfortunate puzzle. Played brilliantly to perfection by the always wonderful Christine Baranski, the elder Dr. Hofstadter is an extremely accomplished woman. Which of the following are Dr. Beverly Hofstadter’s two professions?

Question 22

Which of the following was not a fight that Leonard and Penny had before getting married?

What to say about the couple whose relationship launched a thousand season finale cliffhangers? (Or at least it felt like it.) Leonard may have eventually married his dream girl, but the pair had a long, bumpy road to the altar. But despite their obvious differences in attractiveness, educational achievement, interests, hobbies, and well, just about everything, Leonard and Penny have managed to make it somehow. Which of the following was not a fight that Leonard and Penny had before getting married?

Question 23

Which of the following is not a name of one of Sheldon's cats?

Sheldon Cooper is not crazy – his mother had him tested – but he did go a bit off the deep end when he and Amy Farrah Fowler terminate their boy-slash-friend-slash-girl-slash-friend status after Amy belittles his work in theoretical physics as “cute” as opposed to her chosen field of neurobiology. Naturally, Sheldon seeks a replacement for his then-platonic gal pal and what better replacement than a mini-herd of cats. Which of the following is not a name of one of Sheldon’s cats?

Question 24

What is the comic book store's name?

Like a good gang of geeks, Sheldon, Leonard, Howard and Raj spend a lot of time at the comic book store. Owned by resident sad sack, Stuart Bloom, the comic book store is basically a home away from home for the crew. Aside from Sheldon and Leonard’s apartment, it’s the guys’ main hangout spot until it burned down in a hot plate-related accident in season seven. It was later rebuilt with Howard’s mother’s furniture. The comic book store’s name has only been mentioned once out loud. What is the comic book store’s name?

Question 25

Which of the following is not a Wi-Fi password Sheldon has used to boot Penny off the network?

If there’s one thing Sheldon Cooper can’t stand, it’s a moocher, and early-seasons Penny definitely does her fair share of mooching off the guys. She eats their food, she doesn’t kick in when the takeout bill arrives, and she notoriously leeches off their Wi-Fi signal. Not one to hide his displeasure, Sheldon retaliates at that last injustice in true Sheldon fashion – he picks the most absolutely petty passwords. Which of the following is not a Wi-Fi password Sheldon has used to boot Penny off the network?
