Sheldon: I've been working on a theory about the wave-particle duality of light.
Billy Sparks: I have a nightlight that looks like Spider-Man, but I don't turn it on. [Sheldon looks at George]
George Sr.: Go ahead.
Sheldon: Why don't you turn it on?
Billy Sparks: I'm afraid of spiders.
George Sr.: Yeah, seems like a good place to stop.
Billy Sparks: Now what happens?
Sheldon: You go home.
Billy Sparks: Thank you for your hospitality.

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?

George Jr.: See? They ain't allowed to dance, either.
Missy: It's like I'm watching my life.
George Jr.: That's how I feel when I'm watching Top Gun.

George Sr.: Come on, Sheldon, think of it as a free dinner.
Sheldon: I'm a kid. All my dinners are free.

Dale: Now, what do you think young people talk about on their dates?
Meemaw: I don't know. But my knee's telling me it's gonna rain this weekend.
