Leonard: So, how are you guys doing with all the new events in your womb?

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Leonard: Penny, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. You know maybe I don't need to understand it, I just need to be grateful. I love you, Penny.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

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.
