Howard: Well, congratulations. I'm so happy for you two. Hold on, I have to tell Bernadette. Hey, Bernie, guess what? Sheldon and Amy got engaged. Can you believe it?
Bernadette: (In the bathroom with a pregnancy test) Oh, my God. I cannot believe it.
Howard: She's so happy I think she's crying.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Josh: So, I have to ask, was the robot sexy?
Howard: It was actually just a mechanical hand.
Josh: 'Cause that's all you need, right?
Howard: You are my brother.

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Sheldon: Wait, oh, and I just I want to let you know right now that we are not getting married in a church.
Mary Cooper: That's all right, Sheldon. Anywhere Jesus is is a church.
Sheldon: Well, he won't be at our wedding.
Mary Cooper: He's in my heart, so if I'm there, he'll be there.
Sheldon: Okay, well, then, he's your plus-one. You don't get to bring anyone else.

Mary Cooper: Lord, thank You. Even though You can do anything, that was mighty impressive.

Mary Cooper: I am so happy for you two, but I'm not surprised. I've been praying for this.
Sheldon: Well, God had nothing to do with it. It happened because I was kissing another woman, and it made me realize I wanted to be with Amy.
Mary Cooper: More than one woman was interested in you? I might have prayed a little too hard.
