Meemaw: Let her go. And under no circumstance will you give her that engagement ring.
Amy: What ring?
Leonard: Maybe we should give them some privacy.
Penny: Yeah, yeah, yeah. You go ahead. I'll catch up with you.

Sheldon: Woman, you are playing with forces beyond your ken.
Penny: Yeah, well your Ken can kiss my Barbie.

Leonard: What am I supposed to do?
Penny: Err, keep your mouth off other women.

Leonard: If I take it off, Sheldon wins.
Penny: Sweetie, every night you don't kill him in his sleep, he wins.

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.

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