The Big Bang Theory

Leonard and Sheldon are brilliant physicists—wizards in the laboratory but socially challenged everywhere else. Despite their on-again, off-again relationship, Leonard believes he's found true love with beautiful, street-smart neighbor Penny, and they finally got engaged. Even Sheldon has found a female companion, entering into a "Relationship Agreement" with neurobiologist Amy Farrah Fowler.
