When Leonard's mother arrives at the apartment building for a visit, she meets Penny in the lobby. Dr. Hofstadter and Penny engage in small talk while climbing the stairs to Leonard's apartment, but by the time they get there Penny is in tears after a psychological grilling from Beverly. Leonard is unsurprised by the effect his mother had on Penny. Although Leonard is annoyed by his mother's nature, Sheldon is fascinated by her analytical mind.
When Leonard takes his mother to work, she manages to offend Howard and Raj by suggesting they're in an ersatz homosexual relationship. After trying and failing to get his mother interested in his work, Leonard goes to Penny's apartment to drown his sorrows with her. Meanwhile, Sheldon and Leonard's mother bond over their shared mental brilliance as they return from the hospital with a scan of Sheldon's brain.
While Leonard and Penny start kissing, Sheldon and Dr. Hofstadter have fun of their own with a karaoke game. After Leonard and Penny had progressed to the bedroom, Leonard says the wrong thing and causes Penny to throw him out.
The next day, as Beverly gets ready to leave, Leonard tries to apologize to Penny, who understands and tells him never to speak of it again. As she leaves the apartment, Dr. Hofstadter once again delves into Penny's mind and suggests she travel to New Jersey to have a brain scan.
