This release from the sitcom Big Bang Theory includes all 23 episodes of the show's second season, following the daily misadventures of a group of socially awkward and terminally endearing scientists.

This release includes all 24 episodes of the brainy sitcom The Big Bang Theory, following the romantic and practical misadventures of two genius physicists, who are at the top of their fields in science, but at the bottom of the totem in playing the field. The two continually attempt to bring their social skills into par with their laboratory skills, and living across the hall from a charming blonde actress gives them plenty of motivation.

Physicists Leonard Hofstadter (Johnny Galecki) and Sheldon Cooper (Jim Parsons) continue to contemplate the mysteries of time and space with considerable more ease than the intricacies of sex and dating in the fifth season of The Big Bang Theory.
