[George lumbers into the kitchen, opens the freezer, takes out a bag of frozen peas and applies it to his crotch]
Missy: You don't do that to all the food, do you?
George: I got hurt at practice.
Missy: Blow your whistle too hard?
George: Funny.
Missy: Well, you make it easy.
Mary: George, what happened?
George: Pulled a muscle at practice.
Missy: [o.s.] Also, I'm never eating peas again.

Mary: Missy, if you want a minute with Dad before they close the casket, now's the time. [Missy looks unsure] It's okay if you don't.
Mary: I have to. [Missy stands up and walks up to her father's casket]
[flashback:]
George: Here, let me help you with that. Okay.
Missy: [eats] Holy moly.
George: It's good, huh?
Missy: Unbelievable.
George: I'll leave you to it.
Missy: No, sit with me.
George: Okay.
[present:]
Missy: [crying] Thank you for that. Thank you for everything. [sniffles] I love you.

Sheldon: Is Mom okay?
George: How the heck should I know?
Missy: She left. You can say "hell."

Dr. Sandra Thorpe: Have you always been that way?
Missy: I guess so. I think when you're on your own a lot, you get good at seeing that kind of stuff.
Dr. Sandra Thorpe: Really?
Missy: My dad does football with my older brother, so they're like a team. And my mom and meemaw spend all their time fussing over Sheldon, so they're like a team, too.
Dr. Sandra Thorpe: So no one's on your team?
Missy: Nope. It's just me.

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.
