‘The Big Bang Theory’ Episode Guide (Oct. 23): Sheldon and Koothrappali Confide in Bernadette

“The Collaboration Contamination” (10/23/17) – Sheldon and Koothrappali confide in Bernadette when they can’t handle Amy and Wolowitz working together. Also, Penny and Leonard learn new tactics for how to deal Sheldon from an unlikely source, on “The Big Bang Theory,” Monday, Oct. 23 (8:00-8:31 PM, ET/PT) on the CBS Television Network.

Efrain Gomez guest stars as an Employee.

The teleplay for “The Collaboration Contamination” was written by Dave Goetsch, Maria Ferrari, and Jeremy Howe. This episode was directed by Nikki Lorre.

“The Big Bang Theory” centers around brilliant physicists Leonard and Sheldon – geniuses in the laboratory but socially challenged everywhere else. Enter beautiful, street-smart neighbor Penny, who aims to teach them a thing or two about life.

Despite their on-again, off-again relationship in the past, Leonard and Penny have finally gotten married. Even Sheldon has found a female companion, entering into a “relationship agreement” with neurobiologist Amy Farrah Fowler, and he recently took their relationship to the next level by proposing marriage.

In their free time, Leonard and Sheldon enjoy fantasy role-playing games with their ever-expanding universe of friends, including fellow scientists Koothrappali, Wolowitz and Wolowitz’s adorable microbiologist wife, Bernadette, who is adjusting to life with their new baby girl.

“The Big Bang Theory” stars Jim Parsons (Sheldon Cooper), Johnny Galecki (Leonard Hofstadter), Kaley Cuoco (Penny), Simon Helberg (Howard Wolowitz), Kunal Nayyar (Rajesh Koothrappali), Mayim Bialik (Amy Farrah Fowler), and Melissa Rauch (Bernadette Rostenkowski).

“The Big Bang Theory” is co-created by Chuck Lorre and Bill Prady. It’s produced by Chuck Lorre Productions, Inc., in association with Warner Bros. Television. Chuck Lorre, Bill Prady and Steven Molaro serve as executive producers.
