It doesn’t take a genius like Sheldon Cooper to figure out that some members of The Big Bang Theory just weren’t all that outgoing, but they did go through their own journeys throughout the show’s run that arguably made them more sociable.
Penny’s arrival certainly had a huge effect on those around her such as Leonard and Amy amongst others. But, out of the main cast, who would rank the highest in a social stand-off? Raj, who needs a drink in his hand to speak to 50% of the population? Or perhaps Howard, whose attempts to talk to women have just come across creepy at the best of times? Regardless, there’s a sure-fire hierarchy of social skills amongst the show’s core group.
Sheldon ends up as the member of the group with the lowest social status. Throughout the show’s run, the audience was made perfectly aware that Sheldon’s social circle didn’t extend much further than Leonard, Howard, Raj, Stuart, and their girlfriends.
In the seventeenth episode of season four, titled ‘The Toast Derivation,’ Sheldon hosts a karaoke night which he had to extend his reach further to invite some guests who included Penny’s ex Zack, Barry Kripke, and Levar Burton. Even though they attended, calling them Sheldon’s friends would have been a stretch, to say the least.
Ranking just above Sheldon is Stuart, every fan’s favorite comic book store owner. Even though his social life is almost as non-existent as Sheldon’s, working at the comic book store does mean that Stuart gets to meet a lot of people every day.
Granted, not all of these people will be his friends, but at least he has had positive interactions with Captain Sweatpants and Will Wheaton, which is more than Sheldon can say. However, it is important to keep in mind that Stuart used his comic book store Halloween parties to meet women, and, in his own words, “ninth times the charm.”
Thanks to Penny and Bernadette, Amy went from the socially awkward microbiologist to the much more confident and carefree Amy that fans saw at the end of the show’s run. The show never went into too much detail on Amy’s old relationships before Sheldon.
Once Amy met the other girls, they regularly attended girls’ nights, and she even explores a few new relationships of her own while she and Sheldon took breaks from their relationship. This included a date with Stuart, a sympathy date with Bert from Caltech, and Dave Gibbs.
