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: 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.

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: My point is, while you're spending all this time on your own, building computers or practicing your cello, what you're really doing is becoming interesting. When people finally do notice you, they're gonna find someone a lot cooler than they thought. And for those of you that were popular in high school, it's over, sorry. Thank you. Congratulations.

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.
