Meemaw: Thank you, Moon Pie.
Amy: Uh, I'm curious. Why do you call Sheldon "Moon Pie?"
Meemaw: 'Cause he's so nummy-nummy.
Leonard and Penny: She could just eat him up.

Amy: That's great. And look at you, sitting in Sheldon's spot. You know, I don't even get to sit there.
Sheldon: Yeah. And you never will.

Amy: You have an engagement ring?
Sheldon: Yes.
Amy: Penny, did you know about this?
Penny: All right, let's go.

Meemaw: Moonpie!
Sheldon: Meemaw! I'm so happy to see you!
Meemaw: I'm happy to see you, too!
Sheldon: Oh, you got even smaller. I love it!
