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, Entertainment Weekly).
