George: Okay. Mare, this is where you hand the baby back and let them leave.
Mary: I'm just soaking her up.
George: They don't live in Kansas. [chuckles] You can see 'em whenever you want.
Mary: Okay, well, Nana loves you. Nana's the best. Nana. Nana, Nana, Nana.
George: All right, Nana, take it down a notch.
Mary: Okay. Bring her back anytime. I mean it, anytime.
George: I think they got it.
Georgie: We got it.
Mary: Bye.

Pastor Jeff: And now George's loving wife Mary would like to say a few words. Mary.
Mary: Thank you, Pastor Jeff. Um... [clears throat] I met George in high school. Well, I was in high school. He was an older man with a motorcycle. [light laughter] I'd like to tell you he caught my eye, but actually it was the motorcycle. [laughter] [voice breaking] I'm sorry, I can't... do this. I am... so angry. [sighs] George and I had our ups and downs, but we were finally in such a good place, and then he... left. [crying] He left all of us. I- How could you do that? [Meemaw stands up] I am so mad at him. I'm mad at God, I'm mad at myself for not trying harder while he was here. [Meemaw goes up to Mary] This wasn't supposed to happen. [Mary sobs] [Meemaw hugs Mary] [Georgie hugs a crying Missy]

Sheldon: Mom, when should I be expecting my testicles?
Woman: [turns around] What is wrong with him?
Mary: Nothing is wrong with him. Now turn around before I knock your lights out.
Sheldon: Hello.

Sheldon: Regardless, I'm not interested in making any more friends.
Mary: Oh, I don't think that's how you really feel.
Sheldon: It is. From now on, it's a hermit's life for me.
Mary: I bet, when you grow up, you will be surrounded by lots of smart, wonderful friends.
Sheldon: I can't see that happening.

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.
