Sheldon: Fine, the cat's name is Mittens.
Georgie: Because he has little white feet?
Sheldon: Sure.
George: So, in this thought experiment, do you think Mittens is dead or alive?
Sheldon: There's no way of saying until you open the box.
Georgie: Oh, come on.
Sheldon: Optimistically, I would choose to believe he's alive.
Georgie: Yes!
George: Oh, thank goodness.

George: 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: You know what? I'd be happy to.
Meemaw: What happened to helping me at my yard sale?
George: 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: 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: 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: A little.

Georgie: A bill? Really?
George: Room and board, buddy.
Georgie: $50 a month for food?
George: The way you eat, I should've gone $50 a week.
Georgie: Laundry services?
George: Your poor mother has to touch your underwear.
Georgie: What's the $10 a month "peema" charge?
George: Oh, P-I-M-A, that's a "Pain in My Ass" tax. My way of getting compensated for you taking years off my life.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Mary: Wait, Georgie. Where's your bag?
Georgie: Don't need one. Got my toothbrush right here.
Mary: What about clothes? A change of underwear?
Georgie: Got it.
Mary: Georgie, you're gonna be gone for two days.
Georgie: I'll turn them inside out.

Adult Sheldon: I never did get to see a launch in person, but that was the best trip I ever had. I wish I had told my father while he was alive.
