Missy: "I hope your arm gets better soon. XO, Missy". See? Nothing mean.
Sheldon: Thank you.
Adult Sheldon: My sister could have a big heart. If only that were true of her brain.
Sheldon: That's the wrong "your".
Missy: What are you talking about?
Sheldon: It's supposed to be Y-O-U-R. What you wrote means, "I hope you are arm gets better".
Missy: Oh.
Sheldon: You defaced my body with a grammatical error.
Missy: I guess that's your problem. Y-O-U-R.

Missy: Eat dirt. Eat it.
Meemaw: Kick his ass!
Missy: Does it taste good? Huh?
Dale: Yeah, listen to your meemaw. Kick his ass!
Missy: You gonna cry? Huh? Do it. Cry.
Mary: Do something. Break it up.
George Sr.: H-Hang on. She's winning.
Mary: Missy! Missy Cooper, you stop beating up that boy!
Meemaw: Punch him in the nuts!

Missy: Someone's Underoos are in a knot.
Sheldon: My Underoos are fitting just fine, thank you.
Missy: Then why is there a stick up your butt?
Sheldon: Stop making inquiries about my bottom.
Missy: But I enjoy it.

[Sheldon sits on the top of the couch with his feet on the cushion]
Missy: What are you doing?
Sheldon: I'm practicing the philosophy of cynicism... The ancient Greek view that the rules of society should be ignored.
Missy: If you're gonna break rules, you can do better than that.
Sheldon: How?
[Missy pushes Sheldon off the couch]

Meemaw: Look, you haven't even gotten to the worst part of it yet. They're gonna leave home. They're gonna move to another city.
Mary: Oh, Lord.
Meemaw: They're gonna tell you their loser boyfriend has knocked them up. Just to be clear, that would be you.
Mary: Sorry.
Meemaw: Turned my hair gray overnight.
Mary: I said sorry. Clearly, you're not in the mood to help.
Meemaw: Listen, it's hard being a parent, but if you do it right, they don't need you anymore.
Mary: Well, I don't like that. I get it, but I just don't like it.
Meemaw: Well, I'd point out, you'll always have your husband, but you want me to be "helpful".

Sheldon: Well, that's what I heard. And if Hawking doesn't let it stop him, then I can't let this cast stop me.
Missy: Great. Go back to sleep.
Sheldon: I will, and I'll do it all by myself. [sings] Soft kitty, warm kitty
Missy: Oh, my God.
Sheldon: Little ball of fur Happy kitty, sleepy kitty, purr Purr, purr.

George Jr.: "Have a great summer. Georgie". Normally I'd write, "Have a bitchin' summer", but I figured you wouldn't like that.
Sheldon: I wouldn't.
