Sheldon: How does the future not concern you?
Missy: I guess there's stuff I'm looking forward to.
Sheldon: Like what?
Missy: Going on dates?
Sheldon: Boring.
Missy: Driving.
Sheldon: Scary.
Missy: Getting married. Hopefully to Vanilla Ice.
Sheldon: You want to marry a snow cone?

George Sr.: What are you doing?
Missy: Watching Sheldon struggle with homework. It's so great.

Missy: So, this Dr. Lee is turning your friends against you?
Sheldon: Essentially.
Missy: Classic move. Most girls you find crying in the school bathroom, that was it.
Sheldon: What do I do?
Missy: Well, you're in a tough spot 'cause your personality is ugh.
Sheldon: There's enough people being mean to me right now.
Missy: Sorry.
Sheldon: Can you help me or not?
Missy: It's you against a bunch of college professors. I don't think you can win this one. [Sheldon starts to walk away] Oh. Do any of them have pimples?
Sheldon: No.
Missy: Too bad, I've done a lot of damage with "pizza face."

Mary: Bless us, Lord, for the food we are about to receive and bless the hands that prepared it.
Missy: And bless Mom.
Mary: Thank you. Amen.
Missy: Amen.
George Jr.: Amen.
Sheldon: She's the hands that prepared it. Your blessing is redundant.
Mary: Let's eat.

Adult Sheldon: [hushed] This is why the only bar I frequent is the Genius Bar at the Apple Store.

President Hagemeyer: Okay, so, what's the problem?
Sheldon: I wanted to talk with Dr. Linkletter about puberty.
Dr. Linkletter: And I wanted to avoid litigation.

Missy: Sheldon, there has to be stuff you're excited to do.
Sheldon: Of course. Getting my PhD, winning the Nobel Prize, getting to meet Professor Proton, working with Stephen Hawking.
Missy: Okay, so, when you start to get upset, focus on that stuff.
Sheldon: But... what if I grow up and none of those things ever happen?
Missy: All you can do is try and find out.
Sheldon: Those are the fundamentals of the scientific method.
Missy: No doy.
