Professor Boucher: So, let me guess. You think I'm being too hard on him and you want me to lighten up?
George Sr.: He is having a tough time.
Professor Boucher: It's a tough class.
George Sr.: Look, I get it. I was in the Army, too, I-I'm all for being strict, but... he doesn't even know where he's going wrong. You know, maybe you could just point him in the right direction?
Professor Boucher: You mean, give him the answer?
George Sr.: No, no. Would you?
Professor Boucher: What do you think?
George Sr.: No.
Professor Boucher: See? I didn't give you the answer and you figured it out.

George Sr.: And Sheldon's fine. You know what he's like. If someone took him, I'm sure they'll bring him right back.

Sheldon: There's going to be a lecture on carbon dating at the Natural Science Museum on Saturday. Who would like to take me?
George Sr.: You know what? I'd be happy to.
Meemaw: What happened to helping me at my yard sale?
George Sr.: Ooh, is that this Saturday? I'm sorry. I'm taking him to a lecture on, uh what is it? Carbonation?
Sheldon: Carbon dating. A method of determining the age of artifacts and fossils.
George Sr.: Hey, we could use that to figure out how old your grandma is.
Sheldon: That won't work. You can't carbon-date something that's alive.
George Sr.: Well, then, we'll just chop her down and count the rings.
Meemaw: Oh, George, did my "lump of clay" remark strike a nerve?
George Sr.: A little.

Meemaw: I bowled a new high score last night.
George Sr.: Nice.
Meemaw: I got two turkeys.
Missy: What's a turkey?
Meemaw: It's three strikes in a row.
Missy: Why do they call it a turkey?
Meemaw: Well, when they first invented bowling, they used to just throw frozen turkeys at the pins. Eventually, they switched to balls to cut down on the smell.
George Sr.: Why you lying to her?
Meemaw: I find it keeps my mind sharp.

George Sr.: What are you doing?
Missy: Watching Sheldon struggle with homework. It's so great.

Adult Sheldon: Engineering has a rich and storied history, dating back to ancient times. Some consider it the single most important field of study... Okay, w-wha... no. Stop. I'm sorry. Howard, I can't do this.
Howard Wolowitz: You asked me to write you an introduction to engineering.
Adult Sheldon: Yes, and if I wanted a comedy routine, I'd have gone to Billy Crystal.
Howard Wolowitz: Just let me read it. [clears throat] Engineering has a rich and storied history dating back to ancient times. Some consider it the single most important field of study known to man, from the wheel to the International Space Station, which I went to.
Adult Sheldon: Honestly, this again?
Howard Wolowitz: Like we don't hear about your Nobel Prize all the time.
Adult Sheldon: It's not my fault people ask about it.
Howard Wolowitz: Because you're always wearing it! You have it on right now.
Adult Sheldon: Look how shiny it is.
Howard Wolowitz: [sighs] Just tell your story.

June: I got to admit, I'm a little jealous.
Meemaw: Of what?
June: You.
Meemaw: Why?
June: You have the Dale I never got. I spent a lot of time polishing that turd, and you get all the benefits.
Meemaw: Hey, I put my time in on that, too.
June: Not as much as me.
Meemaw: When I met him, he was a mess.
June: [laughs] You should've seen where I started.
Meemaw: Well, I think we can both agree, he is one lucky turd.
June: Amen, sister.
