Raj: I don't care! And why don't you think I can find a woman for myself?
Mrs. Koothrappali: Because you're twenty-seven, and the closest thing we have to a daughter-in-law is that Jewish boy Howard.

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.

Sheldon: Stop it both of you! All this fighting, I might as well be back with my parents!
*Imitating his Mom* Dammit, George! I told you if you didn't quit drinking I would leave you!
*Imitating his Dad* Well, I guess that makes you a liar, because I'm drunk as hell and you are still here!
*Imitating his Mom* Stop yelling, you're making Sheldon cry!
*Imitating his Dad* I'll tell you what is making Sheldon cry, that I let you name him SHELDON!

Sheldon: You can't make a half sandwich. If it's not half of a whole sandwich, it's just a small sandwich.

Sheldon: Leonard, when that woman moved in three years ago I told you not to talk to her, and now look. We're going to be late for the movies.
