Missy: Ooh, maybe you have a crush on her.
Sheldon: That's ridiculous.
Missy: I don't know.
Sheldon: I don't.
Missy: You care what she thinks, you can't stop talking about her.
Sheldon: I don't have a crush on her!
Missy: Are you sure?
Sheldon: I don't know!

Mary: Missy, if you want a minute with Dad before they close the casket, now's the time. [Missy looks unsure] It's okay if you don't.
Mary: I have to. [Missy stands up and walks up to her father's casket]
[flashback:]
George: Here, let me help you with that. Okay.
Missy: [eats] Holy moly.
George: It's good, huh?
Missy: Unbelievable.
George: I'll leave you to it.
Missy: No, sit with me.
George: Okay.
[present:]
Missy: [crying] Thank you for that. Thank you for everything. [sniffles] I love you.

Sheldon: Is Mom okay?
George: How the heck should I know?
Missy: She left. You can say "hell."

Sheldon: While Dad's gone, I'm the man of the house, and the man of the house has to enforce the rules.
Missy: The man of the house is about to get his teeth knocked out.
Sheldon: Puberty's made you mean.
Missy: I need to know what happened on my show.
Sheldon: And you'll find out when your privileges are restored.
Missy: I can't wait that long, each episode builds on the last. Imagine a Star Trek that ends with "to be continued," and you don't get to continue.
Sheldon: That would never happen, because I follow the rules.
Missy: You are this close to a purple nurple.
Sheldon: [covers nipples] You leave my nurples alone.

President Hagemeyer: I must tell you that Sheldon was very excited to hear that you might be joining us.
Linda: Well, isn't he sweet?
Paige: He's a peach.
Sheldon: All right, I'm here. [to Hagemeyer] Hello. [to Linda] Hello. [coldly to Paige] Hello.
Paige: Hi, Sheldon. I'm so excited for you to show me around campus today.
Sheldon: The only reason I'm doing it is because...
President Hagemeyer: He's excited to do it, I'm excited he's doing it. Are you excited?
Linda: Sure.
President Hagemeyer: Everyone's excited. Yay.
Sheldon: [sighs] Come on, let's go.
Paige: You and me, together again. It just feels right, doesn't it? [Sheldon grumbles]

Adult Sheldon: I wasn't getting the help I needed, so I turned to the smartest resource I knew.
Dr. John Sturgis: [on the phone] Love is a funny thing. They say, "The heart wants what the heart wants," but I think it should be, "The limbic system wants what the limbic system wants."
Sheldon: Finally, someone's making sense.
Dr. John Sturgis: Well, not to brag, but when it comes to unrequited love, I'm kind of an expert.
Sheldon: Well, when I talk to Paige, all she does is drive me crazy.
Dr. John Sturgis: There's a thin line between affection and aggravation. The Roman poet Catullus said, "I hate and I love and I know not why."
Sheldon: I'm not sure what to make of that.
Dr. John Sturgis: Perhaps it'd be more useful in Latin. "Odi et amo..."

Mary: Okay, have a great day. Love you.
Missy: [covers mouth] Love you, too.
Mary: What are you doing?
Missy: I learned it in baseball. When you don't want the other team to see what you're saying.
Mary: It's okay to love your mom.
Missy: At home. Here, you get the hand.
