Random Trivia For This Title:
- One of the shows that survived the 2007 and 2008 writers strike. The show started in 2007, and the strike started in late 2007. This resulted in season one only being seventeen episodes.
- Bernadette did not originally have such a high pitched voice. When she first appeared, she had a rather normal pitch voice and as her character began to take shape, she adopted the quirky high pitched voice which Melissa Rauch says she based off her mother's voice "without the Jersey".
- Penny (Kaley Cuoco) has never had her maiden name disclosed on-screen before. An interview with one of the writers of the show revealed that the writers are aware of this, and due to superstitious reasons are intent on not revealing it ever on-camera.
- Raj (Kunal Nayyar) is Hindu. However, Raj always wears a steel bangle, which would indicate that he's Sikh. In fact, Kunal Nayyar is Sikh.

- Melissa Rauch, who plays the role of Bernadette, a Catholic, in the series, is Jewish in real-life.
