George: Hey, here's a funny prank you can try tonight. When Tam falls asleep, put some shaving cream in his hand and then tickle his nose.
Sheldon: Why?
George: 'Cause then he'll go to, you know, scratch his nose, and he gets shaving cream on his face.
Sheldon: And then what?
George: Well that - that's it.
Sheldon: But I'm a guest in their home, and that doesn't seem like a very good way to repay their kindness.
George: Never mind.
Sheldon: And what if the shaving cream gets in his eyes? That would sting.
George: Sorry I mentioned it.
Sheldon: Also, I didn't bring my own shaving cream. I'd have to use his dad's, and that-
George: Forget it!

Ms. MacElroy: Now, can anyone tell me why Melville shifts the narrative voice from Ishmael to Ahab? [Ms. MacElroy waits for somebody else to raise their hand] Sheldon.
Sheldon: I have a tummyache. I'd like to see the nurse.
Derek: A "tummyache"?
Sheldon: Yes, Derek, I have a tummy and it aches. Ergo, tummyache.
Derek: "Ergo"?
Sheldon: It's Latin, Derek.
Ms. MacElroy: Go to the nurse.
Sheldon: And to answer your question, the shifting point of view grants the reader a broader perspective of events than typically allowed by first-person narration.
Ms. MacElroy: Where were we?
Sheldon: And "ergo" is Latin for "hence," Derek.

Pastor Jeff: Come on up here, Sheldon. Let's hear what you got.
Sheldon: I've spent the last week studying what people believe, and I've come to a conclusion.
Pastor Jeff: And what's that?
Sheldon: I'm starting my own religion.
Pastor Jeff: I'm sorry, what?
Sheldon: I'm calling it Mathology. It's based on a universal binary system.
Pastor Jeff: That's terrific, Sheldon, but this is a Baptist Sunday school.
Sheldon: I know, I'm here to convert everybody. Any takers?
Pastor Jeff: Okay. Let's go have a talk with your mom.
Sheldon: The only sin in Mathology is being stupid.

Mary: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster. For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that. However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that. Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that. But before every meal, it's common for everyone to wash their hands and face. I did like that. Forks are not customary in a Vietnamese household. I did not like that. And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

Georgie: Mornin'.
Mary: Mornin'.
Georgie: I slept in the nude last night. Felt every little breeze.
[Sheldon slides his food away]
Mary: Thank you for sharing that.
Georgie: You're welcome.

George: Sheldon, all you got to do is be cool.
Adult Sheldon: "Be cool." He might as well have asked me to fly around the backyard.
