Ms. MacElroy: Mr. Cooper, you're late.
Sheldon: I know I'm late. My training wheels broke.
Derek: Training wheels?
Sheldon: Yes, Derek! I have training wheels like a child! I also have a job like an adult. I'm a very complicated person!
Ms. MacElroy: Sure. Let's go with complicated.

Ms. MacElroy: Tell you what I do. I send him on little errands. Like the other day, I told him, "Go to the supply room and get me a framastan."
Coach Wilkins: What's a framastan?
Ms. MacElroy: No such thing. I made it up. He was gone the whole period.
Ms. Ingram: [laughs] I'm using that.
Ms. MacElroy: Don't use framastan. That's mine.

Ms. MacElroy: Georgie Cooper?
George Jr.: Here.
Ms. MacElroy: Sheldon Cooper? Georgie, where's your brother?
George Jr.: I don't know.
Ms. MacElroy: Good enough for me.

Ms. MacElroy: That's sweet of you for asking, but I'd rather stick my finger in a pencil sharpener and crank away.

Adult Sheldon: Ignoring things that irritate me isn't my strong suit. Obsessively fixating on them, now that's what gets me out of bed in the morning.

Adult Sheldon: My father's wisdom touched me deeply. Which is why, to this day, no matter what I'm going through, I am never irritating or abusive to any of my friends or loved ones. Ask them. They'll tell you.

Billy Sparks: Hey, Sheldon.
Sheldon: Hello, Billy.
Billy Sparks: Are you our new paperboy?
Sheldon: Yes, I'm joining the work-a-day world.
Billy Sparks: I work, too! I take care of our chickens.
Sheldon: Don't get the wrong idea. When I grow up, I plan on being a theoretical physicist.
Billy Sparks: Cool. I'm sticking with chickens.
Sheldon: All righty then. Have a nice day.
Billy Sparks: You, too. [looking at the newspaper] Oh, cool, it's Monday.
