Stephen Hawking: Are you sitting in a bathroom?
Sheldon: Yes. I needed a place to storm off to and it was all that was available.
Stephen Hawking: Fine. But if I hear a flush, this conversation is over.

Sheldon: I've thought about it, and I really want to spend the rest of my life with Amy. Do I have your blessing?
Stephen Hawking: Well, Sheldon, I think you should make her finger like Saturn and put a ring on it.

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.
