The original The Big Bang Theory pilot was meant to premiere in 2006-2007. It didn't get picked up by the network, though, and never aired. In the pilot, Sheldon was especially different. According to Fandom's wiki for the unaired pilot

Sheldon is significantly different from his series counterpart: he is sexually active, he frequently masturbates (as opposed to his later counterpart Sheldon) and has multiple fetishes, likes dancing and is a bit more social than his counterpart.

And continuing the theme of a more sexualized version of the character, the wiki says Sheldon's proclivities got further explored:

In the episode, it was revealed early that he had slept with Gilda and has a fetish for women with large hind quarters (butts). He has also seen seven women naked, some of whom aren't even his relatives.

Though Sheldon Cooper speaks fluent Klingon and references the Star Trek universe frequently, actor Jim Parsons has never actually seen an episode of the famous sci-fi series.

Another surprise? Though Sheldon frequently references Doctor Who, the actor has never seen that show either. “I have never seen Doctor Who,” Parsons admitted. “I know what it is of course,” he continued, “but I have never watched an episode.”

Stuart always finds himself in an awkward situation, including in the episode “The Hot Tub Contamination,” when he and Raj end up in a hot tub together. The actor who plays Stuart, Kevin Sussman, had a hard time filming the episode, and not because he had to get so close to his costar. 

Sussman has a deep anxiety about being underwater. The crew had to coach and encourage Sussman through the scene on the set. Sussman said, “I don’t like putting my head underwater ever... a bunch of people had to coach me, you know, ‘it’s going to be okay, we have a lot of people around.’

The opening theme song for The Big Bang Theory is so engrained in fans' heads now, it's hard to imagine the show without it. "The History of Everything," composed and performed by the Barenaked Ladies, is played after the cold open of each episode - and it's undeniably catchy. But the first ever episode featured Thomas Dolby's 1982 hit "She Blinded Me With Science" as its theme instead.
