Leonard: Kung Fu letters might not be politically correct.
Mary Cooper: Oh, I thought the one we couldn't say was Ching-Chong.
Leonard: Yeah, that too.

Mary Cooper: Raj is it? Still having trouble talking to the ladies? Because you know at our church we have a woman who's an amazing healer. Mainly she does crutch and wheelchair people. But I bet she'd be willing to take a shot at whatever third-world demon is running around inside of you.

Sheldon: Well, this is confusing for me. But I don't want to stand in the way of your happiness. So, I will condemn you internally while maintaining an outward appearance of acceptance.
Mary: That is very Christian of you.

Mary Cooper: So who else is coming to this shindig?
Amy: Oh, well, the usual gang. Penny's family is coming tomorrow.
Sheldon: Yeah, and Leonards mother's already here.
Mary Cooper: Oh. Beverly. How nice.
Amy: You've met her, right?
Mary Cooper: Yes, I have. (reveals her cross necklace)
Sheldon: Mother, she's an atheist, not a vampire.
Mary Cooper: Either way, let's stop and get some garlic.

(Howard has just told Mary about his upcoming trip to the International Space Station.)
Mary Cooper: I bet your mom is really proud of you.
Howard: Nope. She says if I don't back out, she's gonna go on a hunger strike. It'd take years before she'd be in any kind of danger, but still.

Mary Cooper: It's all themed. There's Jonah and the Whale Watching. All-you-can-eat Last Supper Buffet. And my personal favorite, Gunning with God.

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