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?

Sheldon: I'm no stanger to mimetic epidemiology. At Johnson Elementary school, the phrase Shelly Cooper's a smelly pooper spread like wildfire.

Dr. Koothrappali: Now, hold on. If she is dating an American, that's not a bad way to go. He's Jewish. Those chaps are very successful, and they don't drink a lot.

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.
