Mr. Givens: All right, everyone, we'll pick it up here tomorrow. If we're lucky, we may find a fossil as old as lunch lady Phyllis. You people don't know what's funny.

George: Hey, Hubert. Was Sheldon in class today?
Mr. Givens: Nope. Haven't seen him all week.
George: Weren't you gonna say anything?
Mr. Givens: I didn't want to jinx it.

Mr. Givens: Caltech? Fantastic.
Sheldon: For Caltech? I know.
Mr. Givens: Mm. Well, I'm sure you're gonna do great things.
Sheldon: I hope so. I intend to. I'm being modest. I will.
Mr. Givens: You're taller, but you're still the same.
Sheldon: It's fun, isn't it?
Mr. Givens: Okay. Good luck at Caltech, Sheldon.
Sheldon: I don't believe in luck.
Mr. Givens: Well, here's hoping that a random universe works out in your favor.
Sheldon: Thank you. Bye.
Mr. Givens: Hmm. [to his class] That young man might change the world someday. Or blow it up. Who's to say?

Sheldon: Mr. Givens, I just wanted you to know that I'm still working hard on my campaign to get more funding for the science department.
Mr. Givens: Oh, great, 'cause I've got to dig up tomorrow's worms myself.

Tam: Look at this, my mother left me a note. "You can do better. Mom." Not "Love, Mom," not "XO, Mom," just "Mom."

Sheldon: Excuse me, sir. When you're done urinating, I'd like to ask you some questions about social dynamics, intimidation, threats, et cetera. Finish up, no hurry.

Sheldon: Good news, I just spoke to Tommy Clarkson.
Georgie: What? Are you crazy?
Sheldon: Nope, Mom had me tested.
