The physics of funny is back for year three! At work, CalTech doctors Sheldon Cooper and Leonard Hofstadter and their uber-geek pals Howard Wolowitz and Rajesh Koothrapali rule over the rules of the cosmos. At home, however, on the mean streets of Pasadena – whether it’s dating or day-to-day survival – the real world conquers them. And with one of the universe’s greatest mysteries living next door – an attractive neighbor named Penny – they’ve got their work cut out from them. Emmy® nominee Jim Parsons stars alongside Johnny Galecki, Kaley Cuoco and more in the third laugh-filled season from creator/producers Chuck Lorre (Two and a Half Men) and Bill Prady (Dharma & Greg) that proves the hypothesis that comedy is both an art and a science!
