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! See how your comedy IQ measures up. less
