One of the best things about The Big Bang Theory is that no matter how much the main characters transform and grow over the years, they’re still incredibly similar to the people whom viewers’ first met in season 1. Characters like Amy and Bernadette have shifted personality-wise since their first episode, but they’re consistent in morals and logic.
However, there were rare moments when the main characters said things that didn’t align with their personalities. Everyone from Howard to Penny reacted in ways that seemed odd when looking at their overall character.
Updated on May 13th, 2022, by Lynn Gibbs: The Big Bang Theory had some of the smartest and funniest quotes shown on TV. With the core four being scientists, their witty responses to situations made for entertaining episodes. The Big Bang Theory only got better when Penny, Bernadette, and Amy hung out with the group more consistently. But with 12 seasons to Big Bang Theory’s name, the main characters were bound to have moments or quotes that didn’t match their characters.
Beverly Hofstadter was not the warmest of mothers to Leonard. As a neuroscientist and psychiatrist, Beverly studied her children and ran experiments while producing parenting books on her research. Leonard always hated that he didn’t have the warm, affectionate childhood that so many children deserved.
However, in ‘The Conference Valuation,’ Beverly said something that was out of character. She said the time she spent with Leonard was some of her fondest memories. Considering Leonard thought his mother disapproved of him, this was a shock. Maybe TBBT’s Beverly wasn’t that bad?
In ‘The Rhinitis Revelation,’ Sheldon’s religious mother came to visit him and his friends. Mary had some outlandish quotes throughout TBBT because they were often judgemental, out of touch, and stereotypical. But as a die-hard Christian, Mary said something to Penny that was out of character.
While doing laundry with Penny, Mary questioned a piece of lingerie Penny had. She assured Mary that not every man she brought him got far enough to see her lingerie, which led Mary to say this quote about strawberry wine and a joyride. It’s hard to imagine Mary being so free-spirited with both alcohol and men. It was a side of her that fans never saw before.
When viewers first met Stuart, it was Penny’s first time meeting him as well. After a quick meeting, Stuart appeared cool, calm, and confident as the owner of the comic book store that the guys frequented. While Leonard had a hard time flirting with Penny in season 2, Stuart had no issues.
When Penny asked Stuart if a picture he was drawing was her, Stuart said all the right things that kept Penny flattered and interested. Compared to the Stuart fans got to know in later episodes, this entire exchange was out of character. It didn’t make sense that Stuart went from a smooth ladies’ man to someone so down on his luck.
When Penny and Leonard began dating, Penny wanted to understand what Leonard did for work. With physics outside the realm of Penny’s understanding, Sheldon promised to teach her a thing or two. Penny didn’t care what opinions others had of her dating Leonard, but she wanted to at least understand what he did for work.
After a long and tiring lesson from Sheldon, Penny learned two long-winded sentences that she recited in front of the group. What she said was true but completely out of character, which was why the group had their tongues hanging out of their mouths as she spoke.
It was a smart career decision for Leonard to go away at sea to work with Professor Stephen Hawking’s scientific group as he would be a part of history if their experiment went well. But the trip seemed to be more play than work for Leonard.
When Leonard came back from sea and was about to walk down the aisle with Penny, he admitted that he had cheated on her while he was on the ship. Everything he was saying was completely out of character because he had fought to be with Penny for years. Why would he throw it away for a kiss at sea? Penny (and fans) were disappointed with Leonard because that decision was out of character.
It took Sheldon years to be comfortable enough with Amy to call her his girlfriend. It took him even longer to ask her to marry him. But somewhere along their rollercoaster of a relationship, Sheldon and Amy did an experiment on the combination of their genes. Seeing how brilliant the results were, Amy couldn’t wait to replicate the results. Sheldon, on the other hand, had another idea: he wanted to make a baby.
The realization that they could produce a genius made Sheldon excited. But hearing him say, “We lock that door, lower our underpants a little, and make a baby” was one of the best, albeit, shocking quotes Sheldon has ever said. Sheldon is not fond of personal intimacy, so for him to want to procreate was uncharacteristic of him.
When Howard and Bernadette first started dating, Howard slowly stopped answering her calls. The ups and downs of their relationship were relatable for viewers, but fans couldn’t help but wonder if Howard realized how good he had it with Bernadette.
Howard was always trying to land himself a girlfriend, and when he finally had one that was as beautiful and smart as Bernadette, it was odd that he was suddenly not fond of “commitment.” Out of all the men, Howard was the most desperate for affection.
“Koothrappali Out. God Bless That Boy, I Don’t Know What I’d Do Without Him.”
If there’s one thing that fans would change about Raj’s storyline in TBBT, it would be that he got the happy ending he desperately wanted since season 1. He wanted a wife and kids more than his friends.
In an episode where Raj won an award from People Magazine, his personality shifted. He suddenly thought he was better than his friends and could get any woman he wanted. In one scene, he was on the phone talking to his assistant and sounded cocky, making his friends watch in disgust. It was rare for viewers to hear Raj say “Koothrappali out” on the phone, or even rely so heavily on an assistant he had for one day.
Amy is one character who changed the most throughout the series. She transformed from a robotic and shy woman to someone who was outwardly sexual and spoke her mind.
At the start, Amy told Sheldon that “all forms of physical contact” were off the table. This is incredibly out of character for the Amy fans knew in season 12 because Amy practically begged Sheldon for hugs and forms of intimacy. It’s hard to picture her not wanting to sleep with Sheldon when she asked him to get physical with her for years.
When Bernadette and Howard go on their first date, the only thing the two have in common is their overbearing mothers. The two shared stories of how dominating their mothers were, with Bernadette claiming her mom still picked out her clothes.
This was incredibly strange because as fans get to know Bernadette, they saw how independent she was. Her mother was rarely in her life and she judged Howard for how close he was to his mother. The inconsistent quote from Bernadette was out of character for her because it didn’t match her reality.
