Sheldon: Well, I may never get another chance to see him in person.
Missy: Suck it up. You always get everything you want.
Sheldon: That's not true.
Missy: You got a computer. I'm reading a booger book.

Mary: Georgie is my son I have the right to know who he's spending time with.
Meemaw: You talking about Jana?
Mary: You know her?
Meemaw: Well, I don't really know her. I've seen them hanging out together at Dale's store a couple of times. She's cute.
Mary: Great. So you know even more than I do.
Meemaw: Always have.

Missy: Dad. You missed everything.
George: What happened?
Missy: Georgie lied to Mom to be alone at Jana's house, but Mom knew 'cause she listened in on his phone call.
George: Oh, boy.
Missy: Now he's grounded and everyone's mad. Not me. I'm super happy.
George: Well... bye.

Mary: Let me get a picture of my boys before their big trip.
Sheldon: It's smart to document this. Next time you see me, I'll have been in the presence of Stephen Hawking.
Mary: Smile.
Sheldon: I'd prefer to look serious. This may appear in a textbook someday.
Mary: Say, "Stephen Hawking."
Both: Stephen Hawking.
Sheldon: Aw, you made me smile.

George: All right, 34A and B this is us. All right, you want the aisle or the window?
Sheldon: Which one is assigned to me?
George: It doesn't matter, just pick one.
Sheldon: Well, if I sit by the window, I can watch the takeoff and landing, but if I sit on the aisle, I'm closer to the bathroom.
George: Here we go.
Sheldon: Although if I'm by the window, you'll have to get up when I use the bathroom. But if I'm not, I'll have to get up when you use the bathroom. Just pick one.
Sheldon: It's a tricky decision. My bladder's smaller than yours-
Meredith: Everything okay here?
George: About to be. [picks up Sheldon and puts him in a seat] Here! Aisle it is! We're good.

Georgie: If the point is you made some bad decisions and turned out fine, then why you being so hard on me?
Mary: Because some decisions you cannot walk away from and they will affect the rest of your life.
Georgie: If you're talkin' about Jana getting pregnant, she ain't gonna.
Mary: That is what I thought, and the next thing I know, I'm at the courthouse gettin' married.
Georgie: You got married because you were pregnant?
Mary: Yes.
Georgie: So, I was a mistake?
Mary: No! No! You are a blessin'. The mistake was lyin' to my parents, so that I could spend the night at your dad's house. And, you know, tequila.

Meredith: Take a minute to locate the exit closest to you. The nearest exit could be behind you. Should the cabin experience sudden pressure loss, oxygen masks will drop down from above your seat...
Sheldon: Why would the cabin lose pressure?
George: It won't.
Meredith: Place the mask over your mouth and nose, like this, pull the strap to tighten it. If you are traveling with children, make sure that your own mask is on first before helping your child.
Sheldon: I don't like this at all.
George: It's just a precaution. You know perfectly safe.
Meredith: In the unlikely event of a water landing and evacuation. [echoes] Water landing, water landing, water landing.
Sheldon: I can't do this.

George: If you want to see Stephen Hawking, we have to sit down right now.
Sheldon: It's too dangerous. I can't!
George: It's okay to be scared. Th- That's when you got to dig deep and be brave. So, what do you say?
Sheldon: No, I'm your terrified little boy!

George: You okay, Mr. Spock?
Sheldon: Doing my best, sir. The captain and Mr. Spock don't hold hands.
George: Sorry.
Sheldon: Okay, maybe just this once.
