Leonard and Sheldon are brilliant physicists -- geniuses in the laboratory but socially-challenged everywhere else. Enter beautiful, street-smart neighbor Penny, who aims to teach them a thing or two about life. Despite their on-again, off-again relationship in the past, Leonard and Penny have finally gotten married. Even Sheldon has found a female companion, entering into a "relationship agreement" with neurobiologist Amy Farrah Fowler, and he recently took their relationship to the next level by proposing marriage. In their free time, Leonard and Sheldon enjoy fantasy role-playing games with their ever-expanding universe of friends, including fellow scientists Raj, Howard and Howard's adorable microbiologist wife, Bernadette, who is adjusting to life with their new baby girl.

He's baaack! Sheldon is retrieved from his soul-searching cross-country train trip (older but no wiser) and that means the gang's all here to spread another year's cheer as TV's most attended laugh seminar. Enroll in this comic curriculum to explore Leonard's minor surgery becoming a major catastrophe from his roommate, Howard's obsession over his mom's relationship with retailer-turned-caretaker Stuart, and the peculiar results of Penny's technique as a pharmaceutical sales rep.

This season the Big Bang gang's romantic universe expands. On the rebound from Penny, Leonard falls into the arms of Raj's sister Priya. Sheldon gets a girlfriend, or rather a friend who is a girl: Amy, a dour neurobiologist who declares herself besties with Penny. Howard and Bernadette heat up. And so do Raj and Bernadette (at least in Raj's Bollywood daydream). All in the furtherance of award-winning genius comedy.

This season, they find themselves in a repeating paradigm as they re-create their wedding, this time with family including Penny's mother and brother and Leonard's parents. Meanwhile, the Relationship Agreement between Sheldon and Amy added an entirely new subsection with their annual coitus clause.

Prepare to enter phase nine of television's perpetual laughter experiment as the show 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.

• Disc 2. The Thanksgiving decoupling ; The discovery dissipation ; The Cooper extraction ; The hesitation ramification ; The occupation recalibration ; The convention conundrum ; The locomotive manipulation ; The table polarization
• Disc 3. The friendhship turbulence ; The mommy observation ; The indecision amalgamation ; The relationship diremption ; The anything can happen recurrence ; The Proton transmogrification ; The gorilla dissolution ; The status quo combustion.

Socially challenged they remain, but the scientific geniuses of the show 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 lives, even when they're sitting in a marathon role-playing game.
