    The "geeks" (Leonard and Sheldon) in this show work in the same field at Cal Tech. In what field do they work?The Big Bang Theory

      Physics. There are many physics-related jokes in this show. These comments are surprisingly funny: "You have about as much chance of going out with Penny as the Hubble Telescope has of finding that at the center of each black hole there's a little man with a flashlight trying to find the circuit breaker."

    Penny claims to be a screenwriter, but she's currently working as a waitress. Where does she work?The Big Bang Theory

      The Cheesecake Factory. Wolowitz describes her as "a cheesecake-scented goddess". References have also been made about her smelling like vanilla.

    Two former "Roseanne" alumni play guest characters on the show. One plays Leslie Winkle, Leonard's sometime love interest. Which actress plays Leslie?The Big Bang Theory

      Sara Gilbert. Sara Gilbert was also in the last sitcom on this network with this time slot: "The Class". She played Fern, Richie's not-so-nice wife.

    Another "Roseanne" alumnus is Laurie Metcalf. Whose mother does she play on the show?The Big Bang Theory

      Sheldon's. She plays a very Christian mother who is very perceptive. She claims her other two children are "dumb as soup".

    The theme song is "The History of Everything". Who sings it?The Big Bang Theory

      Barenaked Ladies. They also sing the theme for the Major League Soccer team the Toronto FC (called "TFC"). The band is from Canada.

    Many scenes in "The Big Bang Theory" take place as Leonard and Sheldon are climbing the stairs. Why do they take the stairs?The Big Bang Theory

      The elevator is broken.. There is yellow caution tape in an "X" across every elevator doorway. Sheldon and Leonard use the long climbs to talk about their days.

    In the first season, which character got fired from his job at Cal Tech?The Big Bang Theory

      Sheldon. Sheldon said the wrong thing to his new boss at a party. Eventually, his mom helped him get it back.

    "The Big Bang Theory" hit a road block during its first season on TV. What problem led fans to believe it wouldn't come back for a second season?The Big Bang Theory

      The writers' strike. The strike of the Writers' Guild stopped production of all non-reality television shows towards the end of 2007. As a result, very few of the new shows managed to get a "foothold" in the ratings. On December 4, 2007 Les Moonves, President of CBS, announced that "The Big Bang Theory" and CBS's vampire/cop show "Moonlight" would return for a second season.

    Who goes on a date with Penny?The Big Bang Theory

      Leonard. All of these nerdy guys have think Penny is pretty hot stuff, but Leonard was the only one who actually was able to get a date with her. Unfortunately for Leonard there is never a second date and Penny soon moves on, believing she isn't smart enough to date him.

    The guys enter a team in the Physics Bowl competition with the team name PMS. What did PMS stand for?The Big Bang Theory

      perpetual motion squad. The guys name their team PMS without realizing the more common connection to the acronym, premenstrual syndrome. The team was made up of Leonard, Wolowitz, Raj, and Leslie. They play against Sheldon, who loses the match after refusing to allow his teammates to answer any questions.

    Who still lives with his mother?The Big Bang Theory

      Wolowitz. As the typical 27 year old nerd Howard Wolowitz still lives with his mother, despite believing he is quite the ladies man. He commonly comes on to Penny with a variety of inappropriate comments.

    What secret did Penny entrust to Sheldon?The Big Bang Theory

      She never graduated from community college. Penny was embarrassed that she hadn't graduated from community college. For this reason she feels she isn't smart enough to date Leonard.

    What is the name of the female scientist who works at the same university as Sheldon, and continuously calls him stupid?The Big Bang Theory

      Leslie. Leslie is one of the few "smart" females on this show. She fits right in with all the guys as a scientist at the university where they all work. Leslie is quite promiscuous, and has been with both Leonard and Howard.

    What piece of movie memorabilia do the four guys purchase in an online auction?The Big Bang Theory

      a time machine. For the hefty sum of $800 the guys purchase a full-sized time machine from the movie "Time Machine". They each pitch in $200 for a quarter-share in the time machine.

    Whose last name is Koothrappali? The Big Bang Theory

      Raj. Raj Koothrappali cannot speak to women, including Penny, without the aide of alcohol or medication. In scenes where Penny is present he resorts to whispering to one of the guys, or even writing notes.

    When Sheldon wasn't working at his desk in the apartment, he only liked to sit at one particular spot in his living room. What was his favorite seat?The Cooperisms of "The Big Bang Theory"

      The end of the couch. In the pilot episode, Penny made the mistake of taking Sheldon's spot at the end of the couch when she was invited into Leonard and Sheldon's apartment for the first time. Sheldon had gotten into the habit of choosing where to sit based on variables such as cushion densities, airflow patterns and the dispersion of sunlight, and he did not appreciate being displaced from his pre-determined seat. The reason he liked that particular spot is best explained in his own words: "In the winter, that seat is close enough to the radiator to remain warm, and yet not so close as to cause perspiration. In the summer, it's directly in the path of a cross-breeze created by opening windows there and there. It faces the television at an angle that is neither direct, thus discouraging conversation, nor so far wide as to create a parallax distortion. I could go on but I think I've made my point."

    When Penny first described herself to Leonard and Sheldon in the pilot episode, she revealed one aspect of her belief system that Sheldon was quick to debunk. Which branch of pseudoscience did Penny subscribe to, but which Sheldon felt held no water?The Cooperisms of "The Big Bang Theory"

      Astrology. As a scientist, Sheldon probably wouldn't have accorded much respect to any of these practices, but it was astrology that he expressed disdain for in the pilot episode. Penny had informed Leonard and Sheldon that she was a Sagittarius, and remarked that that probably told them way more than they needed to know about her. Sheldon was in agreement, and responded by saying, "It tells us that you participate in the mass cultural delusion that the sun's apparent position relative to arbitrarily defined constellations at the time of your birth somehow affects your personality." Unsurprisingly, Penny didn't understand what Sheldon was saying. In a subsequent episode, Sheldon referred to astrology as "pseudo-scientific hokum".

    In "The Luminous Fish Effect", Sheldon spent all his time confined to the apartment working on a series of bizarre experiments after he lost his job at the University. Why was Sheldon fired?The Cooperisms of "The Big Bang Theory"

      He insulted his new boss. Sheldon didn't blow up his lab, and probably wouldn't dream of falsifying his results. He also never mastered the plebian task of driving, so he wouldn't have stolen anyone's parking spot. Sheldon got fired from Caltech after he insulted his new boss by calling him a "glorified high school science teacher", and implied that he wasn't "an actual real scientist". His contempt for Dr. Gablehauser was just one example of how Sheldon's arrogance and his belief in his own superiority often got him into trouble with those around him. Sheldon often belittled the work of his friends, and he referred to engineers as "the Oompa-Loompas of science" in "The Jerusalem Duality". When he found out that his sister had been telling her friends that he was a rocket scientist in "The Porkchop Indeterminacy", he equated that to being a toll-taker at the Golden Gate Bridge. In "The Cooper-Hofstadter Polarization", he even implied that he was smarter than Isaac Newton by proclaiming, "Gravity would have been apparent to me without the apple".

    When Penny returned from her trip to Nebraska, Sheldon was dismayed to learn that she might have been exposed to a terrible illness back home. What virulent disease did he fear he would contract from her?The Cooperisms of "The Big Bang Theory"

      The flu. In "The Pancake Batter Anomaly", Sheldon was alarmed to hear that everyone in Penny's family had gotten sick with the flu over the weekend, so he threw her out of the apartment after interrogating her about her level of exposure. "You better go before he starts spraying you with Lysol," advised Leonard, explaining to Penny that Sheldon was a "germophobe". He also tried unsuccessfully to placate Sheldon by telling him that Penny didn’t appear symptomatic. "Oh please," said Sheldon. "If influenza was only contagious after symptoms appear it would have died out thousands of years ago. Somewhere between tool-using and cave-painting, Homo habilis would have figured out to kill the guy with the runny nose." Sheldon's paranoia wasn't confined to just diseases – he didn't like anyone touching his food, and in "The Grasshopper Experiment", we learnt that he showered twice a day and washed his hands as often as he could.

    In "The Hamburger Postulate", Sheldon was confronted with a necktie tied around the doorknob to Leonard's room, but he didn't know what it meant. To whom did he turn for help to interpret this semiotic conundrum?The Cooperisms of "The Big Bang Theory"

      Penny. When Leslie Winkle seduced Leonard one night after a string quartet rehearsal at his apartment, there wasn't a lot of time to give Sheldon the heads-up about Leslie spending the night. Leonard therefore improvised by employing the universal "do not disturb" signal on the doorknob of his bedroom, not realizing that its meaning would be lost on Sheldon because he was eleven when he went to college. Sheldon went across the hall to seek counsel from Penny, who explained the meaning of the tie on the doorknob to him, but this only gave rise to another problem for Sheldon. "I don't know what the protocol is here," implored Sheldon. "Do I stay? Do I leave? Do I wait to greet them with a refreshing beverage?" Penny wasn't much help. "Gee, Sheldon," she said. "You're asking the wrong girl. I'm usually on the other side of the tie." Sheldon settled for calling Leonard on his cell phone to inform him that he had received his message loud and clear.

    When Penny found out that Leonard never celebrated his birthday, she enlisted the help of his friends to throw him a surprise birthday party. The big day finally came, but Penny and Sheldon were tied up at the mall, leaving Howard to stall Leonard by any means necessary. What were Penny and Sheldon buying for the party?The Cooperisms of "The Big Bang Theory"

      A birthday present. In "The Peanut Reaction", Penny noticed that Sheldon hadn't gotten Leonard a birthday present, and demanded to know why. "The entire institution of gift-giving makes no sense," explained Sheldon. "Let's say that I go out and I spend 50 dollars on you. It's a laborious activity because I have to imagine what you need whereas you know what you need. Now I could simplify things – just give you the 50 dollars directly, and you could give me 50 dollars on my birthday, and so on until one of us dies, leaving the other one old and 50 dollars richer. And I ask you, is it worth it?" Sheldon was only convinced to buy a birthday present for Leonard when, at Howard's prompting, Penny told him that it was "a non-optional social convention". "Oh," said Sheldon. "Fair enough."

    In the final episode of the first season, Sheldon had a bone to pick with the Szechuan Palace restaurant over something he ate there. What dish had Sheldon so riled up?The Cooperisms of "The Big Bang Theory"

      Tangerine chicken. To say that Sheldon was a fussy eater would be an understatement, and woe betide anyone who got his food order wrong. He once complained that his sandwich was "an unmitigated disaster", because he was given the right ingredients in the wrong order. "In a proper sandwich," he explained, "the cheese is adjacent to the bread, to create a moisture barrier against the lettuce. They might as well have dragged this thing through a car wash." In "The Tangerine Factor", Sheldon believed that the Szechuan Palace was passing off orange chicken as tangerine chicken, although Leonard thought that he should have been more concerned about what they were passing off as chicken. Ever the perfectionist, Sheldon insisted on learning Mandarin so that he could confront the owner of the restaurant in his native tongue. Unfortunately, Sheldon's linguistic skills left a little to be desired. Amongst the things he mistranslated and said in Mandarin in this episode were "Long live concrete", "Your monkey sleeps inside of me", "Show me your mucus" and "Oxen are in my bed. Many, many oxen."

    When Sheldon's friends tried to get him to learn how to drive, he managed to get his Learner's Permit after answering just one question at the DMV. The question was, "When are roadways most slippery?" What was Sheldon's response?"The Big Bang Theory": Cooperisms from Season 2

      None of these were his answers.. In "The Euclid Alternative", Leonard's schedule at the University made it impossible for him to drive Sheldon to and from work everyday, and Sheldon drove everyone else crazy when he made them take him wherever he wanted to go, so they held an intervention and made an appointment for him at the Department of Motor Vehicles. Naturally, Sheldon had some concerns about the test that he was required to take at the DMV. In the case of the question, "When are roadways most slippery?", Sheldon was quick to point out that a proper answer wasn't listed among the multiple choices on the test. "There are three answers, none of which are correct," Sheldon patiently explained to the frustrated DMV employee. "The correct answer is, 'When covered by a film of liquid sufficient to reduce the coefficient of static friction between the tire and the road to essentially zero, but not so deep as to introduce a new source of friction.'" The clerk at the DMV gave Sheldon his Learner's Permit, and told him to go away.

    In "The Cooper-Nowitzki Theorem", Sheldon attracted the admiration of a female grad student, who became an endless source of encouragement with his work. Unfortunately, she became too controlling and wouldn't let him have any fun, so Sheldon turned to Leonard for help. Which clause of their friendship agreement did Sheldon NOT attempt to invoke to get rid of Ramona?"The Big Bang Theory": Cooperisms from Season 2

      The Cohabitation Rider. Leonard wasn't the first person that Sheldon approached for help; he went to the person with the most experience with his particular problem – Penny. "Apparently, I'm in some kind of relationship," Sheldon explained to Penny, "and you seem to be an expert in ending them." When that didn't work out, he roused Leonard from his sleep in an unsuccessful attempt to solicit his assistance. "I'm invoking the Skynet Clause of our friendship agreement," whispered a desperate Sheldon. "That only applies if you need me to help you destroy an artificial intelligence you created that's taking over the Earth," Leonard replied. Sheldon then tried to invoke the Body-Snatchers Clause, but was reminded by Leonard that it only applied if he needed help to destroy someone they knew who had been replaced with an alien pod. Likewise, the Godzilla Clause only applied if Ramona destroyed Tokyo. In the end, Sheldon ended things with Ramona on his own after she tried to share credit for one of his breakthroughs. Sheldon successfully invoked the Cohabitation Rider of his roommate agreement after Leonard's then girlfriend, Dr. Stephanie Barnett, started living with them in "The Vartabedian Conundrum". Amongst other things, the Rider provided for modifications to the bathroom schedule, refrigerator shelving arrangements and vacuuming frequency to accommodate an additional person living in the apartment.

    Apart from being a germophobe, Sheldon has also displayed signs of being a hypochondriac. After Leonard started dating a surgical resident, Sheldon imagined that he was suffering from various different ailments, and went overboard with his requests for her to treat them. How did Dr. Barnett get Sheldon to leave her alone?"The Big Bang Theory": Cooperisms from Season 2

      She told him that he had an inflamed larynx, so that he would stop talking.. At the start of "The Vartabedian Conundrum", Stephanie was examining Sheldon's ear for signs of inflammation. "You're the doctor," Sheldon complained, "but I'm constantly hearing this annoying sound." Leonard confessed that he was hearing it too, but that it was more of "a relentless, narcissistic drone". When Stephanie gave Sheldon's ear a clean bill of health, he declared that he must have a tumor. Later, he showed up at Stephanie's hospital and insisted on getting a battery of tests, including a cardiac stress test, a full-body MRI, and an examination of his upper gastrointestinal tract ("I already drank the barium"). To get him to leave her alone, Stephanie told him that his larynx was terribly inflamed, and advised him to stop talking immediately. She called it a "Sheldonectomy". It did the trick, and Sheldon spent the rest of the episode using his laptop to communicate with people.

    When Sheldon discovered that Penny had gotten him a present for Christmas, Sheldon purchased six different gift baskets and held them in reserve, to ensure that he would have something of commensurate value to give to Penny in return. What did Sheldon end up giving Penny for Christmas?"The Big Bang Theory": Cooperisms from Season 2

      He gave her all six gift baskets.. In "The Bath Item Gift Hypothesis", Sheldon was dismayed to learn that Penny had bought him a Christmas present. "The foundation of gift-giving is reciprocity," Sheldon explained to Penny. "You haven't given me a gift. You've given me an obligation." When Penny said that he didn't have to get her anything in return, Sheldon quickly disabused her of the notion. "Of course I do. The essence of the custom is that I now have to go out and purchase for you a gift of commensurate value, and representing the same perceived level of friendship as that represented by the gift you've given me." Afraid that he might under or over-reciprocate, Sheldon devised a fool-proof plan when he purchased six different gift baskets of varying sizes, and planned to excuse himself by feigning digestive distress after opening Penny's present so that he could look up the price of her gift and select the basket that was closest in value. Sheldon's plan fell apart when Penny gave him a napkin autographed by Leonard Nimoy, and apologized for it being dirty because he had used it to wipe his mouth. "I possess the DNA of Leonard Nimoy?" Sheldon asked. "Do you realize what this means? All I need is a healthy ovum and I can grow my own Leonard Nimoy!" Sheldon was so overwhelmed that he gave all six gift baskets to a surprised Penny. "I know, it's not enough is it?" he declared, before proceeding to give her a hug.

    When Sheldon tried to befriend Barry Kripke to gain access to a computer at the university that he needed for his work, he agreed to participate in a recreational activity that was outside of his normal sphere of interests. What phobia did Sheldon discover he possessed when he spent the day with Barry?"The Big Bang Theory": Cooperisms from Season 2

      Fear of heights. In "The Friendship Algorithm", Sheldon was having trouble bonding with Barry, so he administered a questionnaire (comprising 211 questions, including an essay) to his current group of friends to discover what they liked about him. When that failed to produce the desired results, he visited the bookstore to acquire a book that summarized the current theories in the field of friend-making. His selection, "Stu the Cockatoo is New at the Zoo", taught him to find a common activity to partake with Barry, which was how Sheldon found himself attempting rock-climbing. Initially, he dismissed any notion that he was acrophobic. "A fear of heights is illogical," he observed. "Fear of falling, on the other hand, is prudent and evolutionary." Sheldon was about halfway up the length of the rockface when he made the mistake of looking down, and came to the realization that he was indeed afraid of heights. He didn't think that he could make it to the top or climb back down, so he opted for passing out.

    In "The Vegas Renormalization", Leonard and Raj took Howard to Vegas to get his mind off a bad breakup, leaving Sheldon to his own devices in California. Far from feeling left out, Sheldon relished the thought of having something for dinner that he normally wouldn't be able to eat if his compatriots were around. What did he plan on having for his dinner?"The Big Bang Theory": Cooperisms from Season 2

      Indian cuisine. Sheldon said that he would "rather have a blowfly lay eggs and hatch larvae in [his] auditory canal" than go to Las Vegas for the weekend, so the rest of the guys went without him. That suited Sheldon just fine, and for dinner he bought himself some Kadhai Paneer, which he described to Penny as "a perfect culinary representation of the freedom this evening holds". "Not only is it Indian cuisine, which Koothrappali loathes," explained Sheldon, "it contains a generous helping of peanuts, which would reduce Wolowitz to a wheezing, 97-pound blister. And finally, its main ingredient is paneer, a farmer's cheese that would cause Leonard to render any room uninhabitable within minutes." Unfortunately, Sheldon locked himself out of the apartment, so he had to enjoy his paneer, and spend the night, at Penny's place.

    In the second season finale, we discovered that Sheldon could be quite the trickster when in the right mood. What word did he repeatedly say in this episode each time Leonard fell prey to one of his pranks?"The Big Bang Theory": Cooperisms from Season 2

      Bazinga!. In "The Monopolar Expedition", the guys were getting ready for a three-month expedition to the North Pole, which placed Sheldon in such a good mood that he kept playing pranks on Leonard. He led Leonard to believe that an equation on his board was wrong, when it wasn't. "I can't comment without violating our agreement that I not criticize your work," Sheldon said, and waited for Leonard to make a correction before telling him that he had gotten it right in the first place. "Once again, you have fallen for one of my classic pranks. Bazinga!" Later, he displayed a rare affinity for sarcasm when he told Leonard, "It appears that Penny secretly wants you in her life in a very intimate and carnal fashion." Leonard fell for it at first, until he realized that he was being "Bazinga-ed" again. Finally, Sheldon hid a pack of flash-frozen brown rice and led Leonard to believe that he had forgotten to bring it on the expedition, before pulling a "Bazinga" hat-trick on Leonard. Something tells me that the trip to the North Pole is going to feel a lot longer than three months.
