The ideal comedy experiment continues as The Big Bang Theory continues in its seventh season. Television's number one series follows six of TV's funniest scientists and their street smart neighbor as they discover life, love and laughs in everything from comic-books to cosmonauts aboard the International Space Station.

Creator/producers Chuck Lorre ("Two and a Half Men") and Bill Prady ("Dharma & Greg") make comedy a science with the second big season of THE BIG BANG THEORY that makes room for new series regular Sara Gilbert (who starred on "Roseanne" with series star Galecki). Check out the physics of funny!

Leonard and Sheldon are brilliant physicists, socially inept outside of the lab. It's up to free-spirited neighbor Penny to teach them a thing or two about life. While Leonard spends his days looking for love, Sheldon is quite content with their ever-expanding universe of friends, including fellow scientists Raj, Howard and Howard's new fiancée, Bernadette and Penny's "bestie" Amy Farrah Fowler.
