List of The Big Bang Theory episodes

The third season of the American sitcom The Big Bang Theory was originally aired on CBS from September 21, 2009, to May 24, 2010, with 23 episodes. It has received higher ratings than the previous two seasons with over 15 million viewers. Season three starts three months after the end of season two when the guys left for the North Pole.

The third season saw the first appearances of future main cast members Melissa Rauch as Dr. Bernadette Rostenkowski in "The Creepy Candy Coating Corollary", and Mayim Bialik as Dr. Amy Farrah Fowler in the season finale "The Lunar Excitation". Christine Baranski submitted the episode "The Maternal Congruence" for consideration due to her nomination for the Primetime Emmy Award for Outstanding Guest Actress in a Comedy Series at the 62nd Primetime Emmy Awards. Jim Parsons won the Primetime Emmy Award for Outstanding Lead Actor in a Comedy Series at the 62nd Primetime Emmy Awards for the episode "The Pants Alternative".

Penny throws herself at Leonard after he returns from three months at the North Pole and they begin a relationship that lasts most of the season, Penny and Sheldon start a quirky friendship though she can still annoy him, Wil Wheaton begins appearing as Sheldon's arch enemy, Howard begins to date Bernadette Rostenkowski and at the end of the season Sheldon meets Amy Farrah Fowler.

The men return home from their three-month expedition at the Magnetic North Pole (from the Season 2 finale), and Penny finally reveals her feelings for Leonard by kissing him as soon as he visits her. Meanwhile, Howard and Raj reveal to Sheldon that they and Leonard tampered with his experiment on magnetic monopoles by using an electric can opener. Sheldon is angry as he had already submitted his results to the university, and is forced to make an apology, making him the butt of jokes from everyone at the university, particularly Kripke. Feeling betrayed, Sheldon returns to his home in Galveston, Texas. On Penny's advice, Leonard, Howard and Raj reluctantly go to Galveston to bring him back. At his home, Sheldon becomes increasingly annoyed with his mother's strict Christian lifestyle. When the guys come over and plead with Sheldon to come back to Pasadena, he initially refuses, but following an argument with his mother about evolution, he forgives them and returns to Pasadena. Penny and Leonard then finally have sex, but both of them now feel their relationship got weird.
