The Big Bang Theory
In Season One physicists Leonard and Sheldon get their lives shaken up when an attractive young woman named Penny moves in to the apartment across from theirs. Leonard begins to develop a love for Penny, while she puts up with his friends Sheldon Cooper - who has a combination of Obsessive Compulsive Disorder and Neurosis, Howard Wolowitz - a sex craved maniac, and Rajesh - who will not speak to her, as he is too shy to talk with girls. Throughout the season: Sheldon loses his job for insulting his new boss, finds his ego bruised by a child prodigy, and finds himself unable to bear being part of a lie that Leonard has told--always attacking the world with a relentless need to assert his supremacy; Rajesh learns that he can talk to girls when he's drunk; and Penny and Leonard go out (in the final episode).
Season Two begins to deal with character development, including Sheldon becoming more and more obsessive, with a characteristic lack of understanding of irony and sarcasm reminiscent of Asperger syndrome. Leonard and Penny's relationship takes a turn for the nasty when they break up, but quickly is resolved and progresses into a stronger friendship than before. In the season finale Penny hints at her true feelings for Leonard. Meanwhile Howard's character remains relatively static. Rajesh manages to briefly apologize to Penny without having consumed alcohol and also attempts to remedy his situation though the use of medications.
