TV/American

Prepare to enter phase nine of television's perpetual laughter experiment as The Big Bang Theory successfully fuses the elements of science and sitcom. Our two genius roommates - Leonard and Sheldon - and their friends are back once again (smarter, but no wiser). Last season, Sheldon went soul-searching (on a train, of course) and was prepared to make some substantial revisions on his Relationship Agreement with Amy, when everything changed. Leonard, meanwhile, was off to Vegas with Penny to finally tie the knot in the season finale.

Sheldon is rescued from his soul-searching cross-country train trip (older but no wiser), and that means The Big Bang Theory gang's all here to spread another year's cheer as TV's most attended laugh seminar. Enroll in the comic curriculum to observe Leonard's minor surgery, which signals a major catastrophe for Sheldon, Howard's obsession over his mom's relationship with friend-turned-freeloader Stuart, and the unexpected results of Penny's technique as a pharmaceutical sales rep.

Socially challenged they remain, but the scientific geniuses of The Big Bang Theory always deliver hilarious results. Leonard returns from his North Sea expedition to find that his relationship with Penny involves more beta-testing than he's ever done in a lab. Howard's attachment issues with the women in his life in particular and Raj's social breakthrough with women in general provide more laughs. Bernadette and Amy stand staunchly by the men in their life, even when they're sitting in marathon role-playing games.

Whether on Earth or above it, hilarity is outrageously universal in TV's most popular comedy featuring four forward-thinking but socially backward geniuses. Fun discoveries multiply: Leonard learns jealousy is bad for a relationship (with Penny) but science is good for seduction (of Penny). Howard finds life on the International Space Station is no escape from terrestrial turmoil between his overbearing mom and his new wife Bernadette. Raj meets someone special who may be a good match, if only he can keep her from fleeing mid-date.

The geniuses of The Big Bang Theory get thrown for a bell curve in all 24 episodes of the phenomenally funny fifth season of the hit show. In "TV's top-rated comedy" (New York Post), Penny and Leonard's relationship is relaunched in full "Beta Test" mode, while Sheldon, Howard and Raj discover the feminine mystique is something that cannot be easily graphed or calculated.

"Four seasons in, it is still laugh-out-loud funny. Every episode, every week," says USA Today's Robert Bianco about the hit series The Big Bang Theory. Subject his conclusion to empirical analysis by watching all 24 episodes of season four on 3 discs. This season, the Big Bang gang's romantic universe expands. On the rebound from Penny, Leonard falls for Raj's sister Priya. Sheldon gets a girlfriend - Amy, a dour neurobiologist who declares herself Penny's BFF. Howard and Bernadette heat up; meanwhile, Raj is romancing her in Bollywood daydreams.

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 science of funny is back! 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, überconfident Leslie Winkler reduces mere men to spineless jellyfish.

Physicists Leonard and Sheldon understand everything from the inescapable gravitational pull of a black hole to the intricate structure of the atom. But take those atoms and assemble them into a woman, and their comprehension comes to a grinding halt. And when Penny, a woman with all those atoms in all the right places, moves in across the hall, Leonard and Sheldon's universe begins to expand in ways they never could have imagined.

Inspired by the real-life experiences of creators Joe Connelly and Bob Mosher's own children, Leave It To Beaver follows the hilarious everyday adventures of young Theodore "Beaver" Cleaver and his older brother Wally. Whether at home, at school or playing around their suburban neighborhood, Beaver always manages to get himself into some kind of trouble, comically learning each valuable lesson life has to offer along the way. Alongside baseball and apple pie, Leave It To Beaver reigns supreme in the pantheon of Americana.
