Overview
The science of funny is back! At work, physicist Leonard and Sheldon and their geek pals conquer the cosmos. At home, real life - from dating to driving - conquers them. This season, Leonard gets a girl. So does Sheldon. (Sheldon?!) Howard drives the Mars Rover into a ditch. Raj woos a terminator. Gorgeous girl-next-door Penny falls under the spell of Age of Conan. And super-smart, überconfident Leslie Winkler reduces mere men to spineless jellyfish. Twenty-two laugh-filled episodes from series creators Chuck Lorre (Two and a Half Men) and Bill Prady (Gilmore Girls) and a talented cast with astronomical comedy IQs shows why Big Bang is such a big hit.
