Dr. John Sturgis: So wait a minute. Are you saying that the particle should be understood as a sequence of functions executed in a manifold?
Dr. Linkletter: He said it, not me.
Sheldon: Actually, that's correct.
Dr. Linkletter: We were both thinking it. That's what's important.
Sheldon: So that would mean...
Dr. Linkletter: Gravity is just the residue of forces within manifolds?
Sheldon: Are you asking me or telling me?
Dr. Linkletter: Telling?
Sheldon: You're right.
Dr. Linkletter: Oh. [John and Linkletter high-five]

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Are we in my office?
Sheldon: No.
Dr. Linkletter: Then these are not my office hours.
Sheldon: Are you using my love of schedules against me?
Dr. Linkletter: [chuckles] Oh, yes.
Sheldon: Well done.

Dr. Linkletter: Sheldon, thank you for coming in. I want to apologize for our little tiff earlier.
Sheldon: You're forgiven.
Dr. Linkletter: Oh. Great. I found something that might be of interest to you. An authentic signature from Richard Feynman.
Sheldon: Where did you get this?
Dr. Linkletter: Details aren't important.
Sheldon: Is this a restraining order?
Dr. Linkletter: Not important.
Sheldon: That's actually a really good way to get autographs. I'll have to keep that in mind.

Jim: Here we are. Grab a shovel and dig in. There you go.
Dr. Linkletter: I spent the summer in Italy once.
Georgie: Bringing back memories?
Dr. Linkletter: No.

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.
