He's baaack! Sheldon is rescued 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.

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 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.

Leonard and Penny went from next-door neighbors to next-door newlyweds with a nuptial excursion to Vegas. 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.

Socially challenged they remain, but the scientific geniuses of 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 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...

Avery's sister has been kidnapped and ransomed for $2,000,000. Desperate, he and his buddies abduct a retired mob boss to try to force him to use his contacts to find the girl.
