Raj: None of our gods have abs like that.
Howard: Yep, that's the last Jew who did sit-ups. Look where it got him.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?

Mary Cooper: I bet your mom is really proud of you.

Mary Cooper: Lord, Mary Cooper here, coming to you from Gomorrah, California.
