Worlds collide in Season 3! A love affair with Penny has opened a big, wide, wonderful world of romance for Leonard. But Sheldon likes the world just the way it was, thank you. All of which makes for a zany comic triangle with brainy, clueless Sheldon and practical, grounded Penny hilariously vying for the role of hypotenuse. This complete 3-Disc, 23-episode Season 3 set also features Raj, Howard, tattoos, football, awkward dates, jail time, Stan Lee, a The Lord of the Rings ring, and all the fun of a series that only gets better. The Big Bang Theory "has transformed from a cute comedy about eggheads and their hottie neighbor into an addictive ensemble piece that could be this decade’s answer to Friends," Lynette Rice wrote in Entertainment Weekly. Bonus features include a tour of the set with Simon Helberg and Kunal Nayyar (Howard and Raj).This release includes all 23 episodes from the third season 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 on par with their laboratory skills, and living across the hall from a charming blonde actress gives them plenty of motivation.
