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.

Georgie: What are you doing?
George: Separating the whites from the colors.
Georgie: Whoa, that's racist.

Mary: Mom, can you make the salad?
Meemaw: Sure.
George: Hey, don't put in any of those little tomatoes.
Meemaw: Hey, I don't tell you how to impersonate a lump of clay. You don't tell me how to make a salad.

Georgie: Maybe you should go across the street and apologize.
George: I can't do that.
Georgie: Why not?
George: 'Cause if I do, it sets a bad precedent.
Georgie: What's Nixon got to do with it?
George: What?
Georgie: You said "bad president," like Nixon. You know, this guy.

Adult Sheldon: Ignoring things that irritate me isn't my strong suit. Obsessively fixating on them, now that's what gets me out of bed in the morning.

Dr. John Sturgis: Did you know that there's a type of vanilla flavoring derived from the anal glands of the North American beaver?
Meemaw: That seems like a fact you could have shared before we started eating.
Dr. John Sturgis: It isn't used very often. I understand it's difficult to, uh, milk the little sacs.
Meemaw: Cool. Okay, new topic.

Georgie: Mornin'.
Mary: Mornin'.
Georgie: I slept in the nude last night. Felt every little breeze.
[Sheldon slides his food away]
Mary: Thank you for sharing that.
Georgie: You're welcome.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George: Talked to Billy.
Missy: Why would you do that?
George: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Georgie: Hey, now that you're treating him like an adult, can I have his allowance?
George: That allowance is for chores, which you already don't do.
Georgie: Come on. We all know I'm your favorite.
Meemaw: You're not even his third favorite.

Billy Sparks: Hello.
Herschel Sparks: Hey.
George: Hey, Billy.
Billy Sparks: Was this fence window always here?
Herschel Sparks: No, son, that's a new fence window.
Billy Sparks: Anybody else getting dizzy?

Dr. John Sturgis: See, this is why we're great together. You teach me about social etiquette, and I teach you about beaver anuses.
Meemaw: [CHUCKLES] It is magical.
Dr. John Sturgis: Did you know "ani" is also acceptable as the plural of "anus"?
Meemaw: And the magic continues.

Adult Sheldon: Even while sleeping, my quest to save the princess continued, which was quite a departure from my usual dreams, such as determining the coolest prime number. Which, by the way, is 73.

Adult Sheldon: Dr. Sturgis was a wise man. It was a learning opportunity. And when the day comes that I'm wrong, I fully plan to admit it.

Billy Sparks: Who's Melissa?
Missy: Me.
Billy Sparks: Then who's Missy?
Missy: "Missy" is short for "Melissa." Like how "Billy" is short for "William."
Billy Sparks: I don't understand.
Missy: You know how your real name is William?
Billy Sparks: I'm Billy.
Sheldon: No, we call you Billy, but your real name is William.
Billy Sparks: But my underpants say "Billy" in them. Mom, is my name William?
Brenda Sparks: [sighs] Yeah.
Billy Sparks: Then whose underpants am I wearing?

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