But there are some memes in particular that simply sum up the show, and its main characters and their personalities, beautifully. It doesn't hurt that there are quite funny as well.

Lots Of Friends

As fans know, Young Sheldon serves as a prequel of sorts to The Big Bang Theory, telling the childhood stories of fan-favorite character, Sheldon Cooper, one of the smartest child geniuses on TV. In Young Sheldon, fans get a glimpse of how Sheldon had trouble connecting with peers and didn't have many friends growing up.

While his mom reassures him that she's confident he will one day have a great group of friends in the top half of the image, the lower half is a screenshot from an episode of The Big Bang Theory with Sheldon smiling and laughing with his tight-knit group. It's one of the few heartwarming memes that sums up the show.

Dresses Like An Adult Vs. Child

It's an obvious fact but so many people didn't notice until it was put together visually in this meme. As a child, Sheldon opted for button-down shirts, slacks, and his iconic bowtie to go to school. He event went with a briefcase in tow.

Completely contrary to that, as a grown man, Sheldon instead chose to dress much more casually, similar to how a child might dress. That almost always consisted of his uniform: a T-shirt featuring a quirky science-themed image or characters from a comic book series or other popular sci-fi movie or TV show franchise. Under it, he always had a long-sleeve shirt of a contrasting color.

Nope, Don't Care

Missy is one of the scene-stealing characters on Young Sheldon, always there with a witty, sassy, or sarcastic remark, even from a very young age. She always felt she was living in Sheldon's shadow given that his quirks and intelligence required a lot more attention.

But Missy found her way to be heard, like when she made comments like this one. She was wise beyond her years and full of don't-care humor. It's no wonder she's one of the most likable characters on Young Sheldon.

Sweet Revenge

This meme perfectly captures the playful and mischievous personalities of both Georgie and Connie, along with how close the grandson and grandmother were. Connie wasn't a typical grandma: she was a rebel much like Georgie, which is why they meshed so well. Connie was sometimes the only person Georgie could confide in.

In this scene, after Dale – one of the best characters introduced late in Young Sheldon - fired Georgie from his sporting goods store for making a critical error that cost him tons of money, Connie ed her grandson in getting revenge on the man who was also her boyfriend at the time.

Every Type Of Sheldon

The meme exaggerates things, of course, since Young Sheldon is the only spin-off of The Big Bang Theory to date while many other shows have several spin-offs. But Young Sheldon is central to this meme that uses Sheldon's name in a variety of other show titles.

Some are inspired by real shows, like Last Sheldon Standing (Last Man Standing) and America's Got Sheldon (America's Got Talent), while others are just plain funny, like Old Sheldon. Arguably the funniest is CSI Sheldon, poking fun at both Young Sheldon and the fact that there have been countless CSI spin-offs.

Not Obnoxious

Sheldon went beyond the realm of precocious into the territory of obnoxious at times. He didn't just showcase his intelligence, he often undermined others, even people of authority, and criticized those who didn't know what they were talking about.

Some of his other behaviors could have been considered obnoxious as well, including incessantly trying to impart knowledge on others who had no interest in hearing what he had to say, and encouraging his family to do things no one wanted to do.

Stealing Glitter

One of Sheldon's defining traits is his inflated sense of self-importance and his ego. Sheldon is not just overly confident, he can often come across as arrogant. And that is perfectly encapsulated in this meme where he explains to Paige and Missy that he could not have possibly stolen their glitter because his personality is sparkling enough as it is.

What's captured in Sheldon's expression as well is his complete commitment to the words. He didn't mean them as a joke, he truly meant it to be fact. It's one of the many quotes that prove Sheldon is the worst on Young Sheldon.

Not So Smart Anymore

Even the smartest person is taken down a few pegs after watching Young Sheldon and hearing the young lead character recite a variety of scientific facts, using jargon that many don't recognize nor understand. So, this meme showing a primate, representing a lower level of intelligence, is indicative of how even a very intelligent person might feel after watching the show.

The meme also pokes fun at how many people like to soak in the dialogue and information they learn from the show, believing to understand it, only to realize they didn't actually learn anything when they try to use the supposed knowledge in a real-world setting.

Eating For Free

One of the tensest but also hilarious relationships on the show is between Connie and George, two of the funniest characters on Young Sheldon. Connie never thought George was good enough for her daughter, and thus she uses any opportunity she can to poke fun at him. Her jokes often target George's abilities as a father, but mainly focus on his weight.

The ribbing that exists between these two is captured perfectly in this meme along with Connie's keen ability to always retort with a witty comeback. Indeed, while George tries to sling mud as well, Connie always seems to get the last word.

That Overused Meme

It's the meme that keeps coming back, used for every TV show, movie, joke, pop culture moment, and scenario. And Young Sheldon is no exception. In this interpretation, the beautiful young woman walking by is the smart science stuff, while the guy turning his head and ogling at her is Sheldon.

Meanwhile, his visibly annoyed girlfriend giving him an angry stare, is dubbed the "activities typical of a child his age." Indeed, central to Young Sheldon is that, while he's a kid, he is not interested in any typical "kid" stuff. He prefers instead to study scientific principles, watch intelligent programming, and soak up as much knowledge as he can.
