STAGE TUBE: Sneak Peek - Leonard Nimoy Guest Voices on THE BIG BANG THEORY, 3/29

On the March 29th episode of the CBS comedy THE BIG BANG THEORY entitled "The Transporter Malfunction", Penny buys Leonard and Sheldon "Star Trek" collectibles as a thank-you, leading Sheldon to be haunted by Mr. Spock. Meanwhile, Raj decides he has met the "Future Mrs. Koothrappali" after his parents set him up on a date. "Star Trek" legend Leonard Nimoy voices Mr. Spock on the episode airing Thursday, March 29 (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.
