Sheldon: Oh, Meemaw got a new set of teeth. Oh, but then she found her old ones. Oh, so now the new ones are just gonna be her church teeth.
Leonard: Fun. Like your Comic-Con Spock ears and your around the house Spock ears.

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?

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: 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.
