Mary Cooper: When I was your age you could have me for a car ride and a bottle of strawberry wine.

Mary Cooper: When your mom gets back, I'm gonna need to apologize for the way I spoke to her.
Penny: Well, come on, she did kinda start it.
Mary Cooper: Doesn't matter. A good Christian would have turned the other cheek. On the other hand, a good Texan would have shot her, so I'll just split the difference.

Mary: He gets his temper from his daddy.
Leonard: Ah.
Mary: He's got my eyes.
Leonard: I see.
Mary: All that science stuff, that comes from Jesus.

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.

(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.

Leonard: You're talking like a crazy person.
Mary: Actually, I had him tested as a child. Doctor says he's fine.
Sheldon: Told ya.
Mary Cooper: Although, I do regret not following up with that specialist in Houston.

Mary: Back home, there's a woman works at the Walmart. Tall, tall girl. Woman could hunt geese with a rake.
