STAGE TUBE: Sneak Peek - Bernadette Reconsiders Marriage on THE BIG BANG THEORY

On Thursday night's episode of the CBS comedy THE BIG BANG THEORY entitled "The Stag Convergence", Bernadette reconsiders marrying Howard after learning about his sexual history. Wil Wheaton returns as a party guest. The episode airs Thursday, April 26 (8:00 - 8:31 PM, ET/PT) on the CBS Television Network. 

On THE BIG BANG THEORY, Leonard and Sheldon are brilliant physicists - wizards in the laboratory, but socially inept outside of it. Enter beautiful, free-spirited neighbor, Penny, who aims to teach them a thing or two about life. While Leonard spends his days looking for love, Sheldon is quite content video-chatting with platonic partner Amy Farrah Fowler, or playing Star Trek 3D Chess with their ever-expanding universe of friends, including fellow scientists Koothrappali and Wolowitz, and Wolowitz' fiancée, the adorable microbiologist, Bernadette.
