Mary: So, you okay?
Sheldon: Why wouldn't I be okay?
Mary: Well, there's a lot of change going on. I know that's not your favorite.
Sheldon: Where is that railroad crossing?
Mary: Would you like to eat in here? I'll make you a plate.
Sheldon: I have to find that sign. It should be in this box. Where is it?

Sheldon: [enters] I can't find my railroad crossing sign.
Georgie: Hey, how about knocking?
Sheldon: Sorry, I've never had to knock on that door before.
Georgie: Well, now you do.
Sheldon: [grunts] I need the crossing sign for my train set. Have you seen it?
Georgie: No, and I've got company coming soon.
Sheldon: Perfect. An extra set of eyes will be helpful.
Georgie: It's a girl, and you need to get out of here.
Sheldon: I'm not leaving until I find it.
Georgie: Is this really about some dumb sign, or is about you being scared to have a room to yourself?
Sheldon: That sign has been there for as long as I've had that railroad set. It may seem insignificant to you, but I need it. Everyone only cares about themselves. You're happy because you got the garage, Missy's happy because she has her own room, but no one cares about my problems.
Georgie: I'll help you look.
Sheldon: Just forget it.

Adult Sheldon: As I struggled, my meemaw began to realize the problem with running a gambling den in the back of a Laundromat was it's still connected to a Laundromat.
Harriet: I put five pairs of undies in here, and now there are four. Your machine ate my undies.
Meemaw: There's a lost and found box right over there in the corner. Just take all you want.
Harriet: I don't want a stranger's undies.
Meemaw: Then let's find your precious undies.

[fantasy:]
Conductor: Next stop, Medford.
Sheldon: That won't be necessary. Keep going.
Conductor: But, sir, your family's waiting to board.
Sheldon: I'm aware. Drive on.
Conductor: But, sir...
Sheldon: I don't need them. I'm fine on my own. Do not stop this train. [whistles blowing]

Dale: So you gonna sell the place?
Meemaw: No.
Dale: Instead of crime boss, you're gonna be a laundry boss. Well, I guess that's just as cool.

Meemaw: I'm gonna open my game room.
Dale: How?
Meemaw: I don't know.
Dale: Move to a new location?
Meemaw: I don't know!
Dale: What about the Laundromat?
Meemaw: Keep asking questions, see what happens.
Dale: Last one.
Meemaw: What?
Dale: How'd you get so pretty?
Meemaw: I hate you.
Dale: I like you.

Adult Sheldon: There were plenty of reasons to be happy my sister moved out. She snored, she teased me. She left her dirty clothes everywhere. Clearly, I was better off without her.
[After Sheldon lays awake looking at the boxes where Missy's bed used to be, he goes and knocks on her bedroom door. Missy opens the door:]
Sheldon: Can I sleep on your floor?
Missy: Come on.

George: Let's just put this down for a few days.
Missy: Why? 'Cause you don't want to hear him complain?
George: Bingo.
