Mary Cooper: Now, when you said on the phone he broke up with a girl, you meant an actual girl? Not something you kids whipped up in a lab?

Leonard: No, she's real.
Mary Cooper: Did they sin?

Leonard: But there is something I should prepare you for.
Mary Cooper: Oh, relax, Leonard. I have raised that boy. I have seen him at his best and I've seen him at his worst. There's nothing he can do that will surprise me.

Mary Cooper: Well, well. That's a powerful smell.

Sheldon: That's preposterous. I'm not pining for anybody.
Mary Cooper: Oh, lamb chop. We can quibble what to call it, but I think we can both agree it's creepy.

Mary Cooper: You should have called sooner.

Mary Cooper: Shelly, dinner's ready.
Sheldon: Coming.
Mary Cooper: No cats!
Sheldon: Aww.

Mary Cooper: Now, the reason I called Amy over was to find out what kind of person she is. Now, after chatting a bit, I have to say that while she is a perfectly ... unique ... young woman, you two are definitely not suited for each other.

Mary Cooper: Well, putting aside the pig Latin. It's a good a thing you two decided to end the relationship so I didn't have to end it for you.

Leonard: I saw what you did there.
Mary Cooper: He thinks he's such a smarty pants. He's no different from any man. You tell him not to do something, that's all they want to do. If I hadn't told my brother Stumpy not to clear out the woodchipper by hand, we'd still be calling him Edward.

Mary Cooper: Now, don't you move. I'll bring over all the food.
Leonard: No, I can do it.
Mary Cooper: Well, isn't that sweet.

Sheldon: What are they doing here?
Leonard: We came to apologize again and bring you home. So why don't you pack up your stuff, and we'll head back?
Sheldon: No, this is my home now. Thanks to you, my career is over, and I will spend the rest of my life here in Texas trying to teach evolution to creationists.
Mrs. Cooper: You watch your mouth, Shelly. Everyone's entitled to their opinion.
Sheldon: But evolution is not opinion, it's a fact.
Sheldon's mom: And that is your opinion.

Mrs. Cooper: By His hand we are all
Sheldon: Fed.
Mrs. Cooper: Give us, Lord, our daily
Sheldon: Bread.
Mrs. Cooper: Please know that we are truly
Sheldon: Grateful.
Mrs .Cooper: For every cup and every
Sheldon: Plateful.
Mrs. Cooper: Amen.

Mary Cooper: Hold your horses, young man. Here in Texas we pray before we eat.
Sheldon: Aw, mom.
Mary Cooper: This is not California, land of the heathen.

Mary Cooper: Whatever. Jesus still loves you.
