Mandy: Hi.
Mary: Oh, come to Nana.
Mandy: There you go.
Mary: Oh, you got so big.
Georgie: I said that to her when she was pregnant. No bueno.

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

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.

Georgie: Okay, in my defense...
Meemaw: You have no defense. You're an idiot.
Georgie: That was a big part of my defense.

Adult Sheldon: I always believed my extraordinary life would be chronicled in numerous biographies. I even used to make up my own titles. My favorites were: "From Texas to Success: the Sheldon Cooper Journey", and "Cooper for Kids", a pre-school introduction to quantum gravity in superstrings. The point is, I knew my formative years would be well-documented, which meant I needed to polish up some of my early academic credentials, especially East Texas Tech.

Sheldon: If W is the Kähler metric on the algebraic variety X, and the canonical bundle KX is trivial, then X is what?
Dr. John Sturgis: A Zariski space.
Sheldon: Wrong. [slaps Dr. Sturgis's hand with his pencil]
Dr. John Sturgis: Hey!
Dr. Linkletter: Obviously, it's an elliptic curve.
Sheldon: Wrong. [slaps Dr. Linkletter's hand with the pencil]
Dr. Linkletter: Hey!

Dr. John Sturgis: Why are you hitting us?
[flashback:]
Mei-Tung: Wrong.
Sheldon: Ow! Why'd you hit me?
Mei-Tung: Pain is the best teacher.
[present:]
Sheldon: I'm teaching you.
Dr. Linkletter: Well, it feels like you're hitting us.
Sheldon: Like you, I struggled with these concepts, but eventually, I mastered them, through hard work, resilience and a healthy dose of knuckle whacking.
