Meemaw: What's going on here?
Sheldon: Wesley Crusher was just accepted into Starfleet Academy, and for his final mission, he's accompanying Picard on a shuttle mission to Pentarus Five.
Meemaw: No. I mean who's your friend?
Sheldon: Oh, he's not a friend. He's a stranger. I met him on a Star Trek bulletin board. He had a copy of the episode Georgie taped over and brought it here.

Mary: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

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.

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

Adult Sheldon: None of my friends had recorded the episode. I called Tam. I called Dr. Sturgis. Those were all my friends.

Adult Sheldon: Fortunately, having a modem granted me access to an even better kind of friend: the kind you don't have to see or talk to.

Adult Sheldon: Many inventions changed people's lives for the better: the light bulb, the polio vaccine, and one that doesn't get enough credit, the home video cassette recorder. It didn't help keep people out of wheelchairs, but it did keep me from missing Star Trek.
