Adult Sheldon: I've always felt the world of subatomic particles would make an excellent video game. Uh, fortunately, thanks to my brain, I've been playing it for years.
Sheldon: You cheeky little muon, you know you don't belong there.
[As Mary turns to missy]
Missy: Don't look at me. He's your kid.

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: How?
[Missy pushes Sheldon off the couch]

Mary: I was just letting you know that if you were having any problems you could come to me with them.
Sheldon: You think I have mental problems?
Mary: Well, not problems. I'm just worried about your future, and when I see you moving subatomic particles around in the air, that makes-
Sheldon: Subatomic particles are real! You talk to an invisible man in the sky who grants wishes. If anyone's mental, it's you.

Sheldon: [to Mary] I am behaving no differently than I ever have. Why are you suddenly so worried about me?
Dr. Goetsch: That is a valid question. Has anything changed recently?
Sheldon: Maybe it's hormonal. When does menopause typically begin?
Mary: It is not my hormones.
Sheldon: Well, it certainly isn't mine. I'm showing no signs of puberty.

Sheldon: Mother?
Mary: Yes?
Sheldon: Is it okay if I use a knife to butter my toast, or are you worried I'll do something crazy with it?
Mary: You can butter your own toast.
Sheldon: Oh, good. You see the toast, too. I was afraid I was imagining it.
