TV Show Fan
It's no secret that Dr. Sheldon Cooper, played by Jim Parsons, is a huge "Star Trek" fan. He often refers to the legendary science fiction program on the show. In real life, however, Parsons has never seen a single episode. Parsons has never seen "Dr. Who," either, which is another of Sheldon's favorite television programs.
Actress Mayim Bialik mentioned in an interview that the school where the major characters work is based on the California Institute of Technology (Caltech). As a matter of fact, real-life Caltech students and staff are often in attendance when the cast and crew films the show.
When actor Wil Wheaton appeared on the show, he sneaked a picture of one of the most infamous props on the show: the coffee table in Leonard and Sheldon's apartment. He posted the photo on his blog and pointed out that set designers paid close attention to detail when constructing the atmosphere. Magazines, such as Mental Floss, and several snacks, including Red Vines licorice, cover the table's surface.
