As Raj gets into the song, Penny enters and his singing turns into a squawk. Beverley: If you want to have intercourse with that girl, find out what kind of cologne her father wore. But she didn't. Ever. Howard: I understand that unlike Leonard, they're at the top of their respective fields. Howard: Just for the record, we're not in an ersatz homosexual relationship. Howard: We'll talk about this later. It's unpleasant and needs to be repeated. Leonard's Mother: Oh, Dr. Beverley Hofstadter. Leonard: Hey, you want to talk about not getting love from a parent. Leonard: Howard lives with his mother and Raj can't speak to women unless he's drunk. Leonard: Oh, yeah, there she is. My mother's coming to visit. Okee-day? On the other hand, an adult Jewish male living with his mother is so common it borders on sociological cliché. Penny (coming out of her apartment): Oh, good morning. Penny and Leonard are in bed. Penny: Look, I was just coming over to talk to you. Scene: Penny's apartment. Sheldon: I have the same problem with him. What was Leonard like when he was little?

Summary: Leonard becomes worried when he learns his mother, accomplished psychiatrist and neuroscientist Dr. Beverly Hofstadter, is coming to visit. On arriving, Beverly meets Penny; by the time they have climbed the stairs to Leonard's apartment, Penny is in tears after being psychoanalyzed over her childhood issues with her father. Sheldon, on the other hand, immediately develops a comfortable relationship with Beverly, who turns out to be as strict and logical as himself. Howard and Raj meet Beverly too, but after learning that Howard still lives with his mother and Raj cannot talk to women, she is quick to declare that they are in an "ersatz homosexual marriage". Leonard later goes to talk to Penny and they comfort each other by discussing their respective childhood issues with their parents. After becoming drunk, Penny and Leonard end up in bed together, but Leonard ruins the moment by invoking psychiatric theory, implying that he is effectively having sex with his mom and she with her dad. Horrified about this, Penny throws Leonard out of her apartment. She wants to talk about it the next day, but Leonard assures her she never has to talk to him ever again.
