Summary

Although oneYoung Sheldoncameo found a way to bring back a member ofThe Big Bang Theory’s cast, the spinoff never repeated this feat.The Big Bang Theory’s cast of characterswere beloved by the show’s viewers, so it was somewhat frustrating whenYoung Sheldonwas announced as the hit sitcom’s first spinoff. A prequel that focused on Sheldon’s childhood necessarily needed to recast Sheldon himself and, as a result of its ‘90s setting,Young Sheldoncouldn’t bring back any other major stars fromThe Big Bang Theory. ByYoung Sheldon’s series finale, the show had found a workaround.

The Big Bang Theory’s older Sheldon narrated the events ofYoung Sheldon, which allowed the series to bring back both Howard and Amy in voice-only cameos.Young Sheldon’s finale also included an on-screen appearance fromThe Big Bang Theory’s versions of Sheldon and Amy, but this was a one-off trick the show couldn’t have pulled off earlier. However, much earlier in its run,Young Sheldon’s cast of charactersexpanded to include another cameo from one ofThe Big Bang Theory’s main stars. The prequel could have repeated the clever trick that facilitated the actor’s return, but inexplicably never did.

Young Sheldon’s Recast Georgie & Mandy Spinoff Character Makes A Big Bang Theory Feud Worse

The news that Young Sheldon’s spinoff Georgie & Mandy’s First Marriage is recasting an existing character could make a Big Bang Theory feud worse.

Penny’s Actor Played A Pool In Sheldon’s Nightmare

Young Sheldonfeatured a voice-only cameo from Penny’s actor Kaley Cuoco, but never repeated this trick in later episodes.Young Sheldonseason 3, episode 10, “Teenager Soup and a Little Ball of Fib,” saw Sheldon try to avoid a swimming test since he was paranoid about public pools proving to be a breeding ground for bacteria. In his nightmare, a seductive pool tried to tempt him into taking a dip by reassuring him of its cleanliness. Here, Cuoco’s talking pool fulfilled the same role as Penny inThe Big Bang Theory, tempting Sheldon out of his comfort zone.

Penny’s familiar dynamic with Sheldon was immediately recognizable when Cuoco made an uncredited cameo appearance.

WhileThe Big Bang Theory’s next spinoffmight bring back the actor’s version of Penny,Young Sheldon’s talking pool was a clever way to get Cuoco back without relying on her character from the original show. Penny was one of the best memorable characters fromThe Big Bang Theoryand her familiar dynamic with Sheldon was immediately recognizable when Cuoco made an uncredited cameo appearance. This makes it clear thatYoung Sheldon’s later seasons could have done the same with the actors who played Raj, Howard, Leonard, Bernadette, and Amy. After all, all of them had unique relationships with Sheldon.

The Big Bang Theory’s Heroes Couldn’t Appear In The Spinoff Series

Obviously, Leonard, Penny, Raj, Howard, Bernadette, and Amy’s adult selves couldn’t show up in a series set decades earlier. However,Young Sheldonprovedthat it could successfully recastThe Big Bang Theory’s heroeswith Cuoco’s cameo. The spinoff had already done the opposite whenYoung Sheldoncast Lance Barber as Sheldon’s father, George Sr., despite the fact that Barber had previously played Leonard’s high school bully Jimmy Speckerman inThe Big Bang Theoryseason 5, episode 11, “The Speckerman Recurrence.” Thus,The Big Bang Theory’s cast members could have played roles akin to Cuoco’s inventive part as a sentient swimming pool.

Howard’s actor, Simon Helberg, could have been the voice of one of Sheldon’s insecurities.

Young Sheldonwasn’t the most experimental sitcom on the airwaves, but the series was prone to some flights of fancy from time to time. Penn and Teller played Sheldon’s zit in a surreal interlude from season 5, so there is no reasonThe Big Bang Theory’s actors couldn’t have cropped up in similar bit parts. Howard’s actor, Simon Helberg, could have been the voice of one of Sheldon’s insecurities, given how often Sheldon dismissed Howard’s credentials. Similarly, Leonard’s actor John Galecki could have voiced his future friend’s conscience, since Leonard was so often a voice of reason for Sheldon.

Young Sheldon Never Revisited Its Clever Big Bang Theory Cameo Workaround

Even Raj’s actor Kunal Nayyar could have returned in a role related to Sheldon’s earliest romantic misadventures. This would have made sense thanks to Raj’s storied inability to win over his love interests.Young Sheldon’s Georgie and Mandy spinoffis unlikely to have a major role for Sheldon since this would make the series little more than a direct continuation ofYoung Sheldon. As such, it is unlikely that this show will bring back any ofThe Big Bang Theory’s stars for similar minor roles. Cuoco’s cameo opened the door for this recurring gag, butYoung Sheldonnever capitalized on its potential.

Sheldon’s memories of his childhood were evidently colored by his future friendship with Penny.

SinceYoung Sheldonwasted some supporting characterswho were unique to the spinoff, it shouldn’t be too surprising that the series didn’t utilizeThe Big Bang Theory’s stars perfectly. Still, it is a shame to look back on Cuoco’s cameo and see how much potential this recurring bit had.Cuoco’s role inYoung Sheldonblurred the lines between the spinoff andThe Big Bang Theory, as Sheldon’s memories of his childhood were evidently colored by his future friendship with Penny.Young Sheldonnever clarified how much Sheldon’s retelling altered the events of the prequel, which could have been interesting.

Young Sheldon’s Best Cameo Proves The Prequel Needed The Big Bang Theory

Sheldon’s narration often saw him refer to events that he wasn’t present for and didn’t know about at the time, lending him some level of omniscience. However,Young Sheldondidn’t explain whether Sheldon was filling in these blanks from research or if his adult personality bled into his memories. For example, although viewers know that Sheldon’s father, George Sr., never cheated on Mary, it is not clear whether Sheldon himself knows that he walked in on some role-play between his parents and not an extra-marital affair. This issue complicatesYoung Sheldon’s bestThe Big Bang Theorycharacter cameos.

In season 2, episode 22, “A Swedish Science Thing and the Equation for Toast,” Sheldon is heartbroken when no one can attend his celebration party for Dr. Sturgis’ presumed Nobel nomination. Sturgis suffers a period of ill mental health when he fails to secure the nomination, leaving Sheldon alone at his canceled celebration. Sheldon cries in a rare moment of emotional vulnerability and wonders if he will ever have close friends, prompting a montage ofThe Big Bang Theorygang’s younger selves. This sweet cameo provesYoung Sheldonalways neededThe Big Bang Theory, despite the limited overlap between their casts.
