At work, physicists 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, ueberconfident Leslie Winkler reduces mere men to spineless jellyfish. Twenty-three 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 I.Q.s show why Big Bang is such a big hit.
Early in the second season of The Big Bang Theory, Sheldon (Emmy nominee Jim Parsons) asks Penny (Kaley Cuoco), "When did we become friends?" For a smart guy, Sheldon misses a lot. But for the record, season 1 answered the question of whether or not an adorkable group of geniuses can become friends with the hot girl next door (yes!). Season 2 shows us what that friendship looks like, and it's awesome, especially when it includes a rousing game of "Rock, Paper, Scissors, Lizard, Spock." Sheldon's roommate Leonard (Johnny Galecki) wants to be more than friends with Penny, but the richest relationship of the show is that of Penny and Sheldon. He uses the "covenant of friendship" to get Penny to give him rides, he engages in an over-caffeinated business venture with her, and in the excellent Christmas episode, they exchange gifts and share a surprisingly touching moment. (Sheldon's midseason efforts to befriend a colleague can't compare.) Penny is forever changed by the guys, even telling a date about Schrodinger's cat and delving into online gaming. The extras, including a gag reel and interviews with the cast and crew, reveal the stars to be as appealing and connected to each other as their characters. --Stephanie Reid-Simons
