Stacker has ranked the top 50 episodes of “The Big Bang Theory” according to IMDb user ratings.
When Leonard’s difficult-to-please psychoanalyst mother comes for a visit, he goes out of his way to earn her praise. To cause him further grief, she and Sheldon bond easily. Her overly analytic nature puts the other guys on edge, but her incessant criticism ultimately benefits Leonard and Penny’s relationship by causing a bonding moment.
In the season 11 finale, Sheldon and Amy finally tie the knot. In the lead-up to their big day, Leonard, Raj, Wolowitz, Bernadette, and Penny are tasked with finalizing details and dealing with the bride and groom’s extended family. Tensions reach an all-time high when Sheldon is late to the ceremony, but his reason, and Amy’s response, proves once and for all that they’re a perfect match for each other.
