1. Penny agreed to date Leonard when Leonard and Penny first met in the pilot episode, and in episode 100 of the show titled “The Recombination Hypothesis” Penny was wearing the t-shirt she wore that day.
Perhaps, their excellent use of such small details made this series loved by millions.
2. Laurie Metcalf, who played the mother of Sheldon in an episode of the series, is also the mother of Zoe Perry, who plays the mother of young Sheldon in the spin off of the show “Young Sheldon.”
This is how they provide the credibility and similarity in the series.
3. Jim Parsons (Sheldon) can really play the terem (theremin), Sheldon’s favorite instrument. This is really interesting, because this instrument, invented by Soviet inventor Leon Theremin in 1920 and named after him, is really hard to play.
Meanwhile Johhny Galecki (Leonard) plays the cello, Mayim Bialik (Amy) Harp and Simon Helberg (Howard) play the piano.
4. There is a theory among TBBT fans that the color of Sheldon’s t-shirts reflects his feelings.
According to this theory, red means: anger, purple: love and passion, green: calmness and self-confidence, yellow: fear, blue: compassion, light blue: hope and orange: greed.
5. The lyrics of the famous “Soft Kitty” lullaby, which we had the opportunity to listen to a lot in the series, belong to an Australian teacher named Edith Newlin who lived in the 1930s.
Newlin’s daughter filed lawsuits against various companies linked to TBBT for copyright infringement. The reason why this song was used in the drama is that Bill Prady’s daughter, one of the producers of the show, sang this song in class when she was in kindergarten.
6. Leonard’s glasses have no glass. According to Johnny Galecki, who plays the role of Leonard, this is because Jim Parsons (Sheldon) has to keep his head up to look after him because he is quite taller than himself.
At these moments, the lights from the projectors reflect off the glass of the glasses and glare.
7. The Sheldon and Leonard characters are named after actor and producer Sheldon Leonard.
8. We watched Penny with the same bag in many episodes.
Even when the bag was changed it looked almost the same as before, it was made of the same brown leather and was exactly the same type.
9. Wolowitz and Koothrappali were absent in the unpublished pilot episode of the series, while the roles of Penny and Leslie Winkle were played by other actors.
Also, Penny was Katie in this unpublished first episode.
10. Sheldon often wears one of his favorite characters, “Flash” printed T-shirts, and Cisco Ramon, one of the characters in the TV series “The Flash,” wore a T-shirt with Sheldon’s famous phrase “this is my spot” to refer to this.
11. The house where Sheldon and Leonard live is a one-story house with one staircase.
For this reason, whenever a scene where the characters descend or exit the stairs is to be shot, the set crews change the appearance of the doors to create a different floor perception.
12. Raj’s apartment and Howard and Bernadette’s house were never seen together in the same episode, because these two flats are set up in the same set, it is impossible to find both at the same time.
13. Each episode of the series is named after a true scientific rule, theory, and experiment, except the pilot episode.
The name of that episode was pilot.
14. Originally it was thought that the name of the drama would be “Penny, Lenny and Kenny.”
15. Although Sheldon knows everything about Star Trek to the finest detail, Jim Parsons never actually watched the show.
16. After the series, a bee species was named “Euglossa Bazinga”.
