1. Penny Wasn't In The Original Pilot


Kaley Cuoco wasn’t in the first pilot for the show because Penny had not yet been created. Instead, there was a character called Katie played by actress Amanda Walsh.

The original pilot was not picked up by any network, but the second one, shot with Kaley, was very well-received. Producer Chuck Lorre only has good things to say about his starring actress. It may very well have been that one character change that sealed the deal.

2. Jim Parsons Failed A Science Class In College

In an interview with Time, Jim admitted that when in college, he actually failed a class on meteorology. He’s always been interested in the topic, but, unlike his character Sheldon, he’s not much of a science whiz in real life.

3. Kaley Cuoco And Johnny Galecki Once Secretly Dated

At the beginning of the show, the two secretly dated for a little bit. Once they split in 2010, they remained very close friends and amicable coworkers. In 2016, they were rumored to be dating again as they were being very touchy during the People’s Choice Awards, but they claimed that nothing was going on.

4. We Have No Idea What Penny's Last Name Is

Mayim, the former Blossom star who plays Amy Farrah Fowler, took a break from acting to casually earn a PhD in neuroscience from UCLA. On top of acting, she still contributes to the science world by keeping students informed about many scientific topics.

She is the only cast member who actually has a career in science.

7. There Is A Bee Named After Sheldon's Catchphrase


“Bazinga,” Sheldon’s catchphrase, inspired the name of a species of bee discovered in 2013. It’s a Brazilian orchid bee named Euglossa bazinga.
