Mary: Something wrong?
Missy: How come math is easy for Sheldon and hard for me?
Mary: I don't know, honey, but you have your own gifts.
Missy: Like what?
Mary: Well, like you have very pretty hair.
Missy: True.

Adult Sheldon: Jean-Paul Sartre said, "Hell is other people." That's humorous because it's true.

Adult Sheldon: My mother never understood that I actually enjoyed being alone.
Solitude allowed me to think about important things, like the effect of gravitational forces as you approach an event horizon, as opposed to less important things, like how many grapes my brother can fit in his mouth.

Mary: I'm gonna keep him company.
George Sr.: Hey, hey, hey, Mary. Mary, think this through. Right now the kids are just ignoring Sheldon. What happens if he's sitting with his mommy?
Mary: They could mistake me for a senior. ... Well, I look younger than you.

Mary: Look at him. Breaks my heart.
George Sr.: Poor little guy, all alone.
Mary: I don't see why - his brother can't sit with him.
George Sr.: Come on, Mary. When you were in high school, would you have lunch with a nine-year-old?
Mary: Yes, I would've.
George Sr.: Well, there's something wrong with you.

Sheldon: You know what I find comforting?
Mary: What's that, baby?
Sheldon: In a world filled with uncertainty, this place will be here forever.

Sheldon: Dad, are you sad that you got fired?
George Sr.: Mostly angry. But, yeah, maybe a little sad.

Sheldon: Hey, he was about to power a clock with a potato.
George Sr.: Not possible.

George Sr.: Missy, go somewhere else. I need to talk to your brother.
Missy: Why don't you go somewhere else and I can watch Duck-
George Sr.: Go!
Missy: I hate everybody.

Professor Proton: Can a clock be powered by an ordinary potato? I hope so, boys and girls, or this is going to be a really boring episode.

George Jr.: I can't be in the same school as him!
George Sr.: Well, I don't see what choice you have.
George Jr.: Right. Ever since he could talk, I quit having any choices.
George Sr.: I know it's hard. I'm telling you, as your coach, quit your whining, get your uniform on and you get your ass back out there.
George Jr.: But what about as my dad?
George Sr.: Your dad is having a bad day. Listen to your coach.

George Sr.: You mean Sheldon? You can't let that bother you.
George Jr.: It doesn't bother you? You got called to the principal's office.
George Sr.: Yeah, that wasn't so great.

Ms. Fenley: You have perfect pitch.
Sheldon: Okay.
Ms. Fenley: Sweetheart, you should really pursue music.
Sheldon: No, thank you. Musicians take drugs. Is there a faculty restroom I could use?

Mary: All I care about is that my son gets the education he deserves, so you all are gonna have to figure this out.
Principal Petersen: Coach, can you help me out here, please? 'Cause I'm dyin'.
George Sr.: I'd rather not.

Principal Petersen: George, you got any thoughts here?
George Sr.: I certainly do. Mary, tell him.
Mary: It's simple. We don't have a choice.
Principal Petersen: Well, you gave it a shot. We wish you luck with Sheldon elsewhere-
Mary: No, no, no. We don't have a choice. He's got to stay here. We can't afford private school. I sure can't homeschool him. He's doing calculus and Euclidean something or other.
Ms. Ingram: Euclidean geometry. Guess where I learned that.
Mary: Yeah, yeah, we know.

Ms. Fenley: Do you know this sonata?
Sheldon: No.
Ms. Fenley: How long have you played the piano?
Sheldon: I don't play piano.

Ms. MacElroy: This is a stupid idea. This boy does not belong in our school.
Principal Petersen: Come on Vicky, it's just the first day. Why don't we all just take a deep breath here?
Ms. MacElroy: The hell with that.

Ms. MacElroy: What?
Sheldon: Also in violation of the grooming code on page 48, article five, subsection B, you have a bit of a mustache.

Ms. MacElroy: All right, everybody, my name is Ms. MacElroy. In addition to being your homeroom teacher, I'll be seeing some of you in my English class, and some of you on the volleyball court. Just to give you a little history, I've been here at Medford for 29 years I taught some of your older brothers and sisters, and sadly, some of your parents. Not much I haven't seen. Until today. I'm sure you're well aware we have a student with us, who, despite his young age, is remarkably gifted. And I expect y'all to make him feel welcome.

Sheldon: Okay. Let the learning begin.
