The Big Bang Theory

The Big Bang Theory boldly crosses the frontiers of science and comedy in the twelfth season of television's perpetual laughter continuum. Drs. Hofstadter and Cooper remain socially challenged, but the two genius roommates and their friends Penny, Howard, Raj, Amy and Bernadette always produce hilarious results.
