On this week's episode of CBS's THE BIG BANG THEORY, Leonard (Johnny Galecki), Sheldon (Jim Parsons), Howard (Simon Helberg), and Raj (Kunal Nayyar) head out to a comic-book convention in Bakersfield, CA dressed as their favorite characters from Star Trek: The Next Generation. The episode entitled "The Bakersfield Expedition" airs Thursday, Jan. 10 (8:00 - 8:31 PM, ET/PT) on the CBS Television Network. Check out a first look below!

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' new wife, the adorable microbiologist Bernadette.
