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.

Billy Sparks: Hello.
Herschel Sparks: Hey.
George Sr.: Hey, Billy.
Billy Sparks: Was this fence window always here?
Herschel Sparks: No, son, that's a new fence window.
Billy Sparks: Anybody else getting dizzy?

Sheldon: How do we love our neighbors when our moms hate each other?
Billy Sparks: Who does your mom hate?
Sheldon: Your mom.
Billy Sparks: Hey, my mom hates your mom. Small world.

Billy Sparks: Who's Melissa?
Missy: Me.
Billy Sparks: Then who's Missy?
Missy: "Missy" is short for "Melissa." Like how "Billy" is short for "William."
Billy Sparks: I don't understand.
Missy: You know how your real name is William?
Billy Sparks: I'm Billy.
Sheldon: No, we call you Billy, but your real name is William.
Billy Sparks: But my underpants say "Billy" in them. Mom, is my name William?
Brenda Sparks: [sighs] Yeah.
Billy Sparks: Then whose underpants am I wearing?

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.

Sheldon: When does the truck bring the papers?
George Jr.: When it does.
Sheldon: That's a tautology.
George Jr.: What?
Sheldon: A tautology. A statement that's true, but uninformative. Hey, you're supposed to be the one teaching me. That's funny.
