Mr. Givens: Remember, tomorrow we'll be dissecting worms! [class groan] Ah, your sadness makes me happy.

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

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.

George Sr.: What do you want, Sheldon?
Sheldon: I want to know why no one told me about this recruitment letter from Caltech.
George Sr.: Let me see that.
Mr. Givens: All right, let's get me drunk.
Sheldon: Hi, Mr. Givens.
Mr. Givens: Aw, come on!

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.

Adult Sheldon: Not all science is created equal. There's physics, the undisputed king of science.
There's chemistry. It's no physics, but it's not a bad way to pass a rainy afternoon. And then there's biology, the squishiest of the sciences.

Principal Petersen: [screams]
Sheldon: [screams]
Principal Petersen: What are you doing, standing there?
Sheldon: I wrote a formal complaint letter to the school board on how much money is spent on football. I was hoping you could deliver it to them.
Principal Petersen: You do realize your father's a coach here.
Sheldon: Yes, sir, I do.
Principal Petersen: Maybe you ought to talk to him about this first.
Sheldon: I did. He didn't care for the idea at all.
Principal Petersen: Well, there you go.
Sheldon: There I go what?
Principal Petersen: Let me see that. "Barbaric sport encourages bloodlust similar to Roman gladiator games Christians, lions money better spent on science and learning." You're joking, right?
Sheldon: Did you see the word "bazinga" anywhere in that letter?
Principal Petersen: Out.
