Ep 8. The Ornithophobia Diffusion

Sheldon is having a difficult time coping with the fact that a bird flew into his apartment and is now living inside of his bedroom. As a result, he develops a fear of birds, known as ornithophobia. In an effort to conquer his fear, Sheldon visits a psychiatrist and undergoes a series of exposure therapy sessions.

Meanwhile, Penny convinces Leonard to take her to a psychics' convention after she discovers that he has a strong interest in the paranormal. While at the convention, they run into Raj, who is busy trying to impress a girl by pretending to be a spiritual healer. The three of them end up attending a seminar on astral projection, where they attempt to project their spirits out of their bodies.

As the episode progresses, Sheldon's fear of birds worsens, causing him to be completely unable to enter his bedroom. In a hilarious turn of events, Howard and Raj cheerfully offer to help Sheldon conquer his fear by bringing a series of birds into his apartment. The situation quickly spirals out of control, however, as the birds escape their cages and terrorize the apartment.

In the end, Sheldon is able to overcome his fear with the help of his friends, but not before the apartment is left in a state of chaos and disarray. The episode concludes with the group coming together to clean up the mess, and Sheldon reflecting on the importance of facing one's fears in order to overcome them.
