The Big Bang Theory Season 4

THE BIG BANG THEORY clued the viewer in on what to expect right from the get-go by naming its two main characters "Sheldon" and "Leonard". Both brilliant physicists, living together in a technology-cluttered apartment, and spending their free time with a circle of fellow geeks from Cal Tech but despite their hyper-intelligence they are hopelessly "backward" on a social level. Our heroes were thrown for a mobius strip when the incredibly beautiful and voluptuous Penny (Kaley Cuoco), a recent divorcee, moved into the apartment next door. Includes all the episodes from series four.
