Season 12
The Big Bang Theory is an American situation comedy created and executive produced by Chuck Lorre and Bill Prady and centered on five characters living in Pasadena, California: roommates Leonard Hofstadter and Sheldon Cooper, both physicists; Penny, a waitress and aspiring actress who lives across the hall; and Leonard and Sheldon's equally geeky and socially awkward friends and co-workers, mechanical engineer Howard Wolowitz and astrophysicist Raj Koothrappali.
Leonard (Johnny Galecki) and Sheldon (Jim Parsons) are brilliant physicists, the kind of "beautiful minds" that understand how the universe works. Wizards in the laboratory, but socially inept outside of it, none of their genius helps them interact with people, especially women.
All this begins to change when a beautiful, free-spirited beauty named Penny (Kaley Cuoco) moves in next door, who aims to teach them a thing or two about life.
Sheldon, Leonard's roommate, is quite content playing Star Trek 3D chess or Klingon Boggle with their ever-expanding universe of socially dysfunctional friends, including fellow Caltech scientists Howard Wolowitz (Simon Helberg), Rajesh Koothrappali (Kunal Nayyar) and more.
However, Leonard sees in Penny a whole new universe of possibilities... including love.
In the Season 12 premiere: "The Conjugal Configuration" - Sheldon and Amy's honeymoon runs aground in New York, while Penny and Leonard discover they are uncomfortably similar to Amy's parents, Mr. and Mrs. Fowler (Teller and Kathy Bates).
Also, Koothrappali insults physicist Neil deGrasse Tyson and starts a Twitter war.
Created by Chuck Lorre (Two and a Half Men) and Bill Prady (Dharma & Greg), who also serve as executive producers along with Steven Molaro (The Class) and Eddie Gorodetsky (Two and a Half Men), The Big Bang Theory stars Johnny Galecki, Jim Parsons, Kaley Cuoco, Simon Helberg, Kunal Nayyar, Mayim Bialik and Melissa Rauch.
The series is from Chuck Lorre Productions, Inc. in association with Warner Bros. Television.
