Ms. Ingram: I'm sorry, why would I want to live next door to you?
Sheldon: Ask Mr. Givens. Apparently, I'm hilarious.

Mary: Sheldon, you need to stop involving yourself in this. You upset Mr. Lundy, and you were rude to the people at the open house.
George Sr.: And he was bugging his teachers at school all day.
Sheldon: But Mr. Lundy said I could help him.
Mary: I don't care. Even Pastor Jeff is talking about buying that house now.
Sheldon: That could work out. His wife's a police officer, so built-in security. And whenever I have a theological zinger, I can call it right over the fence.

George Sr.: You want your boss living next door?
Mary: Not exactly.
Sheldon: You don't have to worry about your boss. There's a district rule that says that Principal Petersen cannot live next door to me.
Missy: That sounds made-up.
Sheldon: A principal who tells lies. What are we gonna do with this one?

Mary: So, Sheldon, little bit of dental news. You have a baby tooth that never fell out.
Sheldon: Neat. Even my teeth are stubborn.

Richard Feynman: [v.o.] All right, hang on. Where is the fun in finding things out if some joker with a bird head just tells you the answer?
Sheldon: But a grand unified field theory would explain the universe.
Richard Feynman: Answers are all well and good, but a real scientist loves the thrill of the chase. Am I right, Hawking?
Stephen Hawking: [v.o.] I would agree. I do also enjoy the thrill of rolling over bubble wrap with my chair.
Professor Proton: It-it is fun to pop that stuff, isn't it?
Stephen Hawking: So fun.

Sheldon: But what if I never figure it out?
Albert Einstein: I never did and my scientific career is nothing to sneeze at.
Richard Feynman: Same here.
Stephen Hawking: Agreed.
Professor Proton: Uh, don't-don't look at me. I-I drive a Yugo.

Sheldon: I also found this letter from Caltech. I wonder why she was hiding it.
Missy: So read it.
Sheldon: I'm not allowed to. It's not addressed to me.
Missy: Who cares?
Sheldon: The U.S. Postal Service is a government agency. Mail is protected by federal law.
Missy: I'll read it.
Sheldon: Don't. If you do, I'll be an accessory to the crime.

Adult Sheldon: I never understood why kids didn't like being sent to the principal's office. I thought it was great.
Principal Petersen: Sheldon, you are a remarkable young man.
Sheldon: Thanks, and you're a remarkable old man.
Mary: Sheldon.
George Sr.: So you sure he's got all the credits he needs?
Principal Petersen: Yeah, between his coursework and his AP tests, he's met all of his academic requirements. He even managed to get a good grade in P.E.
Sheldon: I earned extra credit snitching on kids who were smoking behind the equipment shed.
Principal Petersen: I don't have to buy cigarettes for a year.

Principal Petersen: One other bit of business. Since you're graduating early, and you're top of the class, that makes you our valedictorian.
George Sr.: Way to go, buddy!
Mary: I'm so proud of you, baby.
Sheldon: You seem surprised.
Mary: Well, it's quite an accomplishment.
Sheldon: Being top of the class in this school? I don't think so.
Principal Petersen: We're really gonna miss you.

Sheldon: I imagine my leaving will be hard for you.
Tam: Oh, yeah, being best friends with a little kid really boosted my game with the ladies.
Sheldon: Makes sense. I'm a conversation starter.

Sheldon: Dad, you need to take me home.
George Sr.: Why? What's the matter?
Sheldon: I don't have my safety goggles. Let's go.
George Sr.: Sheldon, I'm busy.
Sheldon: You're just watching TV.
George Sr.: I'm reviewing game tape.
Sheldon: So you know how it ends. I'll meet you at the car.

Kimberly: We're here with the Cooper family. Mary, George and eleven-year-old Sheldon, who's going to be Medford High School's valedictorian. Mom and Dad, you must be so proud.
George Sr.: Oh, very proud.
Mary: But we're proud of all of our children.
Sheldon: She has to say that.

Sheldon: I was a little worried about missing Professor Proton, but I'm going to tape it and watch it at night. Once I'm in college, can we push my bedtime to 8:30?
Mary: Let's talk bedtime when we're not on the news, honey.
Sheldon: I'm sure it'll work out since I have all summer to recalibrate my bathroom schedule.
Mary: Let's not talk about that, either.

Kimberly: Sheldon, tell us what you're gonna miss the most about high school.
Sheldon: Nothing.
Kimberly: Really? Not your teachers, your friends?
Sheldon: I only have one friend. And I don't think he's gonna miss me because he already found other people to have lunch with.
Mary: Oh, I'm sure he'll miss you.
Sheldon: And I said I'm okay with watching Professor Proton at night, but that'll never work. I get overtired... everybody knows that!
George Sr.: Maybe we could turn the camera off.
Sheldon: And the other day, I couldn't find my safety goggles and I freaked out in school, and my dad asked is this how I plan on acting when I get to college, and I said no, but it probably is because even though I'm smart, I'm just a little boy!
Kimberly: I think we have enough.
George Sr.: Cut.

Sheldon: The train museum's looking for a docent.
Mary: What's a docent?
Sheldon: It's a person in a museum who gives information on the exhibits.
Mary: Do you think they'd let someone your age do that?
Sheldon: Why not? I have a high school diploma.
Mary: True.
Sheldon: I know more about trains than anybody.
Mary: True.
Sheldon: And I have the unique ability to wear people down until I get my way.
Mary: So true.

Sheldon: [on the phone] Hello. I understand you're looking for a docent. I'm 11 years old, but you should know I have a high school diploma and I know more about trains than anybody. You still sound on the fence.
Adult Sheldon: It was time to break out my unique ability.
Sheldon: Let me tell you about every model train I own and what each of them means to me. The first locomotive I ever received...
Adult Sheldon: Wouldn't you know it, 47 short minutes later, I got the job.

Mary: Sheldon, you sure about this?
Sheldon: Yes, leave the crusts on. I'm a docent now.

Lawrence: I like your conductor's uniform.
Sheldon: You know what they say. Dress for the job you want. Do I get an "ask me" button, too?
Lawrence: Well, thank you for asking, and yes, you do. I'll be right back. [exits]
Sheldon: Do you see that bell? That's from Texas and New Orleans locomotive number 701. I'd tell you more, but you haven't contributed the suggested donation.
[Sheldon stares at Meemaw until she puts some money in the donation box]
Sheldon: Number 701 was built in 1930 by the Baldwin Locomotive Works. It was a superheated 44 class GS-1 with ...
Meemaw: I want my money back.
Lawrence: Here you go.
Sheldon: Thank you. [to Meemaw] I know you're supposed to pick me up at 4:00, but I may live here now.
Meemaw: Send me a Christmas card.

Lawrence: Just let me know if you have any questions.
Sheldon: This is a very nice builder's plate. How can you be sure it's not a replica?
Lawrence: Now, that is a great question.
Sheldon: Thank you. I also know the answer. Do you?
Lawrence: Well, there's, uh, rust and soot on the back of it from when it was mounted to the engine's smokebox.
Sheldon: Very good. Ah, the 1947 Santa Fe diesel. I've always loved that paint scheme. I wonder if they had a name for it.
Lawrence: Cat's Whiskers.
Sheldon: Correct.
Lawrence: Ha! Two for two.
Sheldon: Did you know that the word "train" comes from the French verb traîner, which means to draw or drag?
Lawrence: [chuckles] Well, I just learned something.
Sheldon: Well, if you enjoy learning things, then you and I are on the "fast track" to friendship. Speaking of fast tracks, the Japanese bullet train, or Shinkansen...

Sheldon: It's almost opening time. Can I flip the sign?
Lawrence: Have at it.
Sheldon: [pulls out stopwatch] Five, four, three, two, one. [flips sign] We're officially open for business. [Sheldon peeks outside to see nobody waiting for the store] Anticlimactic.
