  • Quotes (10)

    • Sheldon: What are the odds that two individuals as unique as ourselves would be connected by someone as comparatively workaday as your son? Beverly: Is that a rhetorical point, or would you like to do the math? Sheldon: I'd like to do the math.

    • Sheldon: I've always hated how my right frontal lobe looks in pictures. Beverly: Common complaint among men—nothing's ever big enough. Except when they get a tumor—then you don't hear the end of it.

    • Penny: What was Leonard like when he was little? Beverly: Oh, I think you mean young. He's always been little.

    • Penny: Wait, wait, [Beverly] is not going to come here looking for you, is she? Leonard: Relax, she took Sheldon into a hospital to get a brain scan. Penny: Oh, my God, what happened? Leonard: Nothing. Mother likes looking at brains, and Sheldon likes getting his brain scanned.

    • Leonard: Howard lives with his mother, and Raj can't speak to women unless he's drunk. Go! Beverly: Oh, that's fascinating. Selective mutism is quite rare. On the other hand, an adult Jewish male living with his mother is so common, it borders on sociological cliché. Howard: It's just temporary. I pay rent. Leonard: He lives in the same room where his bassinet was. Beverly: You know, both selective mutism and an inability to separate from one's mother can stem from a pathological fear of women. It might explain why the two of you have created an ersatz homosexual marriage to satisfy your need for intimacy. Howard: Say what?
