Although Young Sheldon has countless unforgettable one-liners, The Big Bang Theory spinoff had at least one quote every season that truly defined the show and its characters. By Young Sheldon’s finale, The Big Bang Theory’s spinoff had outgrown its origins as an extension of the hit sitcom. Characters like Sheldon’s father, George Sr., and his mentor, Dr. Sturgis, had become as popular among viewers as The Big Bang Theory’s Stuart or Leslie Winkle. Meanwhile, the family sitcom had proven just as quotable as its hang-out show predecessor. Young Sheldon’s spinoff Georgie & Mandy’s First Marriage has big shoes to fill.
Young Sheldon’s spinoff Georgie & Mandy’s First Marriage has a chance to explain why The Big Bang Theory’s Meemaw is nothing like her younger self.
Fortunately, if Young Sheldon’s success is any metric, the upcoming sitcom will be able to win over viewers. Even though Young Sheldon was set decades before The Big Bang Theory, transplanted its action from California to Texas, and switched formats, the sitcom’s characters still soon won over viewers. Young Sheldon’s cast of characters was what made the series work, from the rebellious Meemaw to Sheldon’s well-meaning but impulsive brother Georgie. A look back on each season’s best quote proves how much character comedy was the foundation that underpinned all of Young Sheldon’s success from its pilot to the series finale.
7“I’m ahead of my time? Alright, call me when you catch up.”
Season 1, Episode 6, “A Patch, a Modem, and a Zantac”
Season 1, episode 6, “A Patch, a Modem, and a Zantac,” saw Sheldon dismissed by a visiting NASA scientist who refused to take his suggestions seriously. Undeterred, the ever-confident Sheldon visited the Johnson Space Center with his supportive father George Sr. in tow. There, he was informed that his plans were theoretically valid, but the technology required to put his ideas into action did not exist yet. His confidence renewed, Sheldon uttered the unforgettable quote that set his over-sized ego in stone for future outings of the show.
Self-centered egotism eventually became Sheldon’s biggest Big Bang Theory character flaw but, in this early Young Sheldon outing, it was entirely justified.
Although Young Sheldon’s title character was always pretty self-assured, he also struggled with confidence like any other kid. What made this quote from “A Patch, a Modem, and a Zantac,” so great was its glimpse of Sheldon’s future self, a character whose brazen self-certainty often got him into trouble. Self-centered egotism eventually became Sheldon’s biggest Big Bang Theory character flaw but, in this early Young Sheldon outing, it was entirely justified. Sheldon’s discovery that he was right, but the world simply wasn’t ready for him was a major reassurance for a character so often isolated and mocked.
6“They’re not temper tantrums! He just has strong opinions.”
Season 2. Episode 5, “A Research Study and Czechoslovakian Wedding Pastries”
Although Sheldon got a hard time from his classmates, teachers, his community, and even his own family members at times, that does not mean the show’s hero had no one in his corner. Young Sheldon’s Mary was fiercely protective of her child-prodigy son, defending Sheldon both when he needed her help and when he was entirely in the wrong. Mary remained Sheldon’s greatest support throughout The Big Bang Theory, putting aside their differing beliefs to coddle her son even as he entered his thirties. This was contextualized in season 2, episode 5, “A Research Study and Czechoslovakian Wedding Pastries.”
When Missy and Sheldon partake in a scientific study of twins, Mary is quick to dismiss George Sr.’s mention of Sheldon’s frequent tantrums. According to Mary, these are merely “Strong opinions,” a euphemism that highlights just how much Sheldon’s mother strains to defend him even from his own family. Mary’s role in Georgie and Mandy’s spinoff will be interesting as it is the first time viewers have seen her without Sheldon, and defending her son was a full-time job in both earlier shows.
5“That’s okay. You’re still my dad, and I’m genetically obligated to love you.”
Season 3, Episode 7, “Pongo Pygmaeus and a Culture that Encourages Spitting”
In “Pongo Pygmaeus and a Culture that Encourages Spitting,” Sheldon starts an online flame war on the early internet with the support of his colleague and mentor, Dr. Sturgis. Sheldon and Sturgis’s exchanges regarding highly scientific, terminology-heavy insults to lob at other academics almost warrant a mention here, but it is his response to George Sr. in conversation that perfectly encapsulates their fraught dynamic. When George Sr. admits to Sheldon that he doesn’t understand a word of his technical jargon, Sheldon tells him he loves him regardless during one of the pair’s sweeter exchanges.
What makes this scene so important is that this unsuspecting moment from “Pongo Pygmaeus and a Culture that Encourages Spitting” captures a pivotal element of Sheldon and George Sr.’s relationship. George Sr. never fully understands his son and, as a result, struggles to see eye to eye with him. However, the pair still put in an effort to bridge the gap between their intellects, and George Sr. still cares for his son. In his own strange way, via quotes like this, Sheldon proves that he cares for his father, too.
4“I checked. We’ve been taking the same ones all year.”
Season 4, Episode 12, “A Box of Treasure and the Meemaw of Science”
In “A Box of Treasure and the Meemaw of Science,” Georgie begins photocopying tests and selling them to his fellow students to help them cheat. He is eventually busted but, thanks to some handy knowledge of a teacher’s questionable extracurricular activities, he gets off scott-free. Early on in this subplot, Georgie informs Tam that he can cheat on his chemistry test by using Sheldon’s completed test, as he saw the teachers recycle the same exams. This is a notable moment of ingenuity from Sheldon’s brother and viewers get a glimpse of The Big Bang Theory’s version of Georgie at this moment.
While Sheldon is a genius, Missy is still a bright, traditionally smart kid. In contrast, Georgie is a figure of fun in his family due to his dim wit. However, by the time viewers meet him in The Big Bang Theory, he has matured into a successful business owner. This is thanks in part to hard work, but it is also the result of characters consistently underestimating him. Georgie isn’t Young Sheldon’s smartest character, but he is smart enough to make money off old chemistry tests, and this quick thinking shapes his success later in life.
3“But you already have two jobs: Church, and Mom.”
Season 5, Episode 12, “A Pink Cadillac and a Glorious Tribal Dance”
In “A Pink Cadillac and a Glorious Tribal Dance,” Sheldon admonishes his mother for even considering the option of taking on another job. He reminds her that she already has two occupations, “Church and Mom,” and illustrates an underrated aspect of his character in the process. Sheldon is still a kid beneath all his intelligence and his affection for his mother shines through when he acknowledges the work involved in her parenting. However, he is also cautious and self-centered, so he can’t imagine a world where his mother isn’t constantly on call.
Throughout The Big Bang Theory and Young Sheldon, Sheldon often struggles to think of other people’s feelings. One of The Big Bang Theory’s worst Penny plots saw him turn down acting lessons from his friend since he didn’t think much of her skills as a thespian. This arrogant attitude has its roots as far back as Young Sheldon season 5, episode 12, with Sheldon telling his mother her purpose in life and seeming surprised when she pushes back. Sheldon struggles with change and, even as a child, likes people to remain in their pre-ordained roles.
2“Probably having a party. Then Sheldon will complain about them having a party, and they’ll stop, because he gets everything he wants.”
Season 6, Episode 16, “A Stolen Truck and Going on the Lam”
In season 6, episode 16, “A Stolen Truck and Going on the Lam,” Missy steals George Sr.’s truck and goes on an ill-advised road trip with McKenna Grace’s troubled child prodigy Paige. Although the pair share a lot of fun exchanges during this trip, one throwaway line from Missy illustrates the great tragedy of her entire character arc. When Paige asks how Missy imagines her family is reacting to her disappearance, she bitterly says they will most likely be delighted by her absence.
By “A Stolen Truck and Going on the Lam,” Missy’s frustration with Sheldon’s preferential treatment has calcified into teenage rage.
She then complains that any party the family might throw would, even in her imagination, be subject to Sheldon’s whims. Missy and Sheldon’s troubled relationship dates back to Young Sheldon’s earliest episodes, when Sheldon was lavished with attention due to his intellect. By “A Stolen Truck and Going on the Lam,” Missy’s frustration with Sheldon’s preferential treatment has calcified into teenage rage, and she sees her family as Sheldon’s entourage of enthusiastic cheerleaders. This is a belief that The Big Bang Theory’s Georgie shares and one that sadly alienates Sheldon from his siblings later in life.
1“I have been and always shall be your friend.”
Season 7, Episode 13, “Funeral”
In season 7, episode 13, “Funeral,” Sheldon finds that he can’t stop replying to the last conversation he had with his father during the preparations for George Sr.’s funeral. Sheldon imagines countless things he could have said to George Sr. as he left for work, some funny, some sincere, and some completely out of character. However, it is Sheldon’s imagined Star Trek reference that bridges the gap between reality and imagination and allows him to acknowledge his unique love for his father. Sheldon imagines himself quoting the seminal sci-fi series to his father, and George Sr. replying with “Live long and prosper.”
9.15 million viewers tuned in to watch Young Sheldon season 7, episode 13, “Funeral,” when it originally aired in May 2024.
The quote is vital to understanding Sheldon’s character as, although it is itself a quote from a sci-fi series set in a far-fetched future, the line allows Sheldon to access his real feelings through a medium he comprehends. “Funeral” is Young Sheldon’s most ambitious episode, and Sheldon’s imagined exchange with his father is the closest the show comes to capturing the essence of their imperfect bond. Young Sheldon’s protagonist lives in his head while George Sr. occupies inthe real world but, in this brief scene, The Big Bang Theory’s hero imagines connecting with his late father in a language they both understand.
