Dr. Koothrappali: Well, if you're not coming out, why did you call us during the cricket semi-finals?
Raj: 'Cause I, I'm tired of trying to meet someone and, I think I'd like you to help me find uh, a wife.
Mrs. Koothrappali: And just to clarify, a female wife?

Mrs. Koothrappali: Please tell me you're not dating an American. I knew this would happen. Rajesh, are you letting your sister date that little Howard boy?

Raj: Hello, mommy.
Mrs.Koothrappali: Hello, Rajesh. What a nice surprise.
Raj: Well, I've been thinking about you. Are you happy, mommy?
Mrs.Koothrappali: Such a sweet boy for asking. I can't believe you come from the poison seed of your father.

Raj: Hello, Mummy. Hello, Daddy. How are you?
Mrs. Koothrappali: We're very rich in a very poor country. So, all in all, can't complain.

Leonard: Once you open the box it loses its value.
Penny: Yeah, yeah. My mom gave me the same lecture about my virginity. I gotta tell you, it was a lot more fun taking it out and playing with it.

Leonard: You went to the comic book store by yourself?
Penny: Yeah, it was fun. I walked in and two different guys got asthma attacks. It felt pretty good.

Raj: No, I'm not gay. If anything, I'm metrosexual.
Dr. Koothrappali: What's that?
Raj: It means that I like women, as well as their skin-care products.
